Answer: x = -7
Step-by-step explanation:
3x-4=-25
add 4 on each side
3x=-21
both are divisible by 3
x=-7
Y=2/3x+8
Y=1/2x+10
What is x?
Answer:
May you please give me the brainliest answer:
To find the value of x, we can set the two given equations equal to each other, since they both represent the same value of y:
2/3x + 8 = 1/2x + 10
We can simplify this equation by first getting rid of the fractions. To do this, we can multiply both sides of the equation by the least common multiple of the denominators, which is 6:
6(2/3x + 8) = 6(1/2x + 10)
4x + 48 = 3x + 60
Next, we can isolate the x term on one side of the equation by subtracting 3x from both sides:
4x - 3x + 48 = 60
Simplifying this gives:
x + 48 = 60
Finally, we can isolate x by subtracting 48 from both sides:
x = 60 - 48 = 12
Therefore, x = 12.

PQRST is a solid regular pyramid on a square base QRST
where QR = 20 cm and edge PQ = 30 cm.
Find
a the height of P above the base QRST
b the angle that PS makes with the base QRST
c the total surface area of the pyramid including
the base.
Answer: a) To find the height of the pyramid, we can use the Pythagorean theorem. Let H be the height of the pyramid, and let M be the midpoint of QR. Then, PM is half of PQ, which is 15 cm. We can use the Pythagorean theorem to find H:
H^2 = PQ^2 - PM^2
H^2 = 30^2 - 15^2
H^2 = 675
H = sqrt(675) = 5 sqrt(3) cm
b) To find the angle that PS makes with the base QRST, we can use trigonometry. Let A be the foot of the perpendicular from P to the base QRST, and let B be the midpoint of PS. Then, we have:
tan(angle PSB) = AB / PB
Since triangle PAB is a right triangle, we can use the Pythagorean theorem to find AB:
AB^2 = AP^2 - PB^2
AB^2 = H^2 + (PQ/2)^2 - PB^2
AB^2 = (5 sqrt(3))^2 + (15/2)^2 - PB^2
AB^2 = 225/4 + 75 - PB^2
AB^2 = 375/4 - PB^2
Since triangle PBS is also a right triangle, we can use the Pythagorean theorem to find PB:
PB^2 = PS^2 - BS^2
PB^2 = (2 H)^2 - (PQ/2)^2
PB^2 = 4 (5 sqrt(3))^2 - (15/2)^2
PB^2 = 500 - 56.25
PB^2 = 443.75
Substituting these values into the equation for tan(angle PSB), we get:
tan(angle PSB) = sqrt(375/4 - 443.75) / sqrt(443.75)
tan(angle PSB) = -0.4385
Since angle PSB is in the second quadrant, we have:
angle PSB = 180 degrees + arctan(-0.4385) = 152.4 degrees (rounded to one decimal place)
c) To find the total surface area of the pyramid, including the base, we can divide the pyramid into four triangular faces and a square base. The area of each triangular face can be found using the formula:
area = (1/2) base * height
where the base is the length of one edge of the square base, and the height is the height of the pyramid. The area of the base is simply the area of the square QRST, which is (20 cm)^2 = 400 cm^2. Therefore, we have:
area of each triangular face = (1/2) (20 cm) (5 sqrt(3) cm) = 50 sqrt(3) cm^2
total surface area = 4 (50 sqrt(3) cm^2) + 400 cm^2 = 200 sqrt(3) cm^2 + 400 cm^2
total surface area = (200 + 200 sqrt(3)) cm^2 ≈ 532.4 cm^2 (rounded to one decimal place)

1- What is the connection between exponential function and geometric sequence.
Exponential functions and geometric sequences are closely related, as the terms in a geometric sequence can be expressed using an exponential function.
A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant called the common ratio. For example, a geometric sequence starting with 2 and with a common ratio of 3 would be: 2, 6, 18, 54, 162, ...
The general formula for a geometric sequence is:
a_n = a_1 * r^(n-1)Where:
a_n is the nth term of the sequence.a_1 is the first term of the sequence.r is the common ratio.n is the number of terms.Exponential functions have the general form:
f(x) = a * b^xWhere:
a is a constant.b is the base.x is the exponent.If we take the formula for a geometric sequence and rewrite it as an exponential function, we get:
a_n = a_1 * r^(n-1) = a_1 * (1 + (r-1))^(n-1)Using the binomial expansion formula, we can simplify this to:
a_n = a_1 * (1 + (r-1))^(n-1) = a_1 * (1 + (r-1)*(n-1))This is an exponential function with base (1 + (r-1)) and exponent (n-1). Therefore, the terms of a geometric sequence can be expressed using an exponential function.
Conversely, if we have an exponential function of the form f(x) = a * b^x, then we can find a geometric sequence by evaluating the function for a range of values of x. For example, if we take f(x) = 2 * 3^x and evaluate it for x = 1, 2, 3, 4, we get the geometric sequence 6, 18, 54, 162.

What is result of the following expression when x is 125? x %6 a. 0 b. 5 c. 20.5 d. 20.
Option b. 5. The number 125 can be written as 6 times 20 plus 5. Therefore, when x is 125, the expression "x % 6" evaluates to 5.
The adage "x % 6" signifies the rest of x is separated by 6. At the point when x is 125, the rest of 125 is partitioned by 6 can be found by playing out the accompanying whole number division:
125 ÷ 6 = 20 remaining portion 5
This implies that 125 can be composed as multiple times 20 in addition to 5. Consequently, when x is 125, the adage "x % 6" assesses to 5.
So the response is (b) 5.
At the point when we utilize the modulo administrator (%) to track down the rest of x partitioned by 6, the maxim "x % 6" assesses to 5 when x is 125. This is on the grounds that when 125 is separated by 6, the remainder is 20 with a rest of 5. At the end of the day, 125 is equivalent to multiple times 20 in addition to 5. Accordingly, the rest of 125 is partitioned by 6 is 5, and that is the aftereffect of the adage "x % 6" when x is 125.

In 2023 the college tuition at a state university was $8,000. Each year the tuition
rises by 3%. In what year will the tuition reach $10,000?
By using the concept of interest, we can calculate the year in which the tuition will reach $10,000 as 2027
Interest is the extra money you pay for borrowing money or for an investment, and it accumulates over time.
In this case, the interest rate is 3%, so the total tuition increases by 3% each year. To calculate the year in which tuition will reach $10,000, we will need to use the following formula:
Interest = (principal × rate × time) / 100.
The principal is $8,000, the rate is 3%, and the time is the number of years it takes for the tuition to reach $10,000. Thus, the equation becomes:
Interest = (8000 × 0.03 × time) / 100.
We can solve for time by multiplying both sides of the equation by 100 and dividing by 240. This gives us the following result:
Time = ($10,000 - $8,000) / (0.03 × $8,000) = 4.17 years.
Therefore, the tuition will reach $10,000 in

A bicycle store costs $4200 per month to operate. The store pays an average of $55 per bike. The average selling price of each bicycle is $195. How many bicycles must the store sell each month to break even?
The store must sell 30 bicycles each month to break even.
To break even, the total revenue from selling bicycles must be equal to the total cost of operating the store. Let's calculate the revenue and cost of the store for selling x bicycles in a month.
Revenue from selling x bicycles = selling price per bike × number of bikes sold
= $195x
Cost of operating the store = fixed cost + variable cost
= $4200 + (cost per bike × number of bikes sold)
= $4200 + ($55x)
To break even, the revenue must equal the cost. So we can set up the linear equation equation:
$195x = $4200 + $55x
Solving for x, we get:

what quadrant does the terminal ray of the angle drawn in standard position lie in? drag an angle measure to each box to match the quadrant location o
In the coordinate plane, an angle drawn in standard position has its initial side on the positive x-axis and its vertex at the origin (0,0).
What is quadrant?In geometry, a quadrant is one of the four regions of the coordinate plane created by two perpendicular axes, usually the x-axis and y-axis. The coordinate plane is divided into four quadrants, numbered from I to IV in a counterclockwise direction, with the origin (0,0) at their intersection. Each quadrant is defined by the signs of the x- and y-coordinates of points within that quadrant. Specifically:
Quadrant I is where both x and y are positive.
Quadrant II is where x is negative and y is positive.
Quadrant III is where both x and y are negative.
Quadrant IV is where x is positive and y is negative.
Quadrants are commonly used in trigonometry, where they help define the signs of the trigonometric functions sine, cosine, and tangent, which can be used to find the ratios of the lengths of the sides of right triangles. They are also used in the Cartesian coordinate system to locate and plot points on the plane, and to represent various mathematical relationships and models.
Here,
The terminal ray of the angle can lie in one of the four quadrants, depending on the direction of the angle:
If the angle is between 0 and 90 degrees (exclusive), its terminal ray lies in the first quadrant, which is the quadrant to the right and above the origin.
If the angle is between 90 and 180 degrees (exclusive), its terminal ray lies in the second quadrant, which is the quadrant to the left and above the origin.
If the angle is between 180 and 270 degrees (exclusive), its terminal ray lies in the third quadrant, which is the quadrant to the left and below the origin.
If the angle is between 270 and 360 degrees (exclusive), its terminal ray lies in the fourth quadrant, which is the quadrant to the right and below the origin.
To determine the quadrant in which an angle lies, you can either use the degree measure of the angle or the sign of its trigonometric functions (sine, cosine, tangent) in the different quadrants.
