Answer:
The answer is A) (-4/3, -1/2)
Step-by-step explanation:
All you need to do is take the given values of x and y from all the ordered pairs, and plug them into the equation y=3/4x+1/2
The ordered pair A has the values:
x=-4/3, y=-1/2
Now we substitute:
-1/2=3/4×(-4/3)+1/2
-1/2=-1+1/2
-1/2=-1/2
Both sides are equal, so the ordered pair is the solution.
You can repeat the same steps with the other ordered pairs, but they won't be the solution.
Hope this helps!

I believe it's A.
Step-by-step explanation:
The formula for the perimeter of a rectangle: 2(l + w)
Since we have not found x, you would assume it hasn't been doubled yet by the 2. Since the width = 14, it is doubled to 28.
Next, we know from looking at the formula that l and w are added together, so inside the brackets is an addition problem. ( + 28)
Since we know that l = x and l has to be doubled, it will be = (2x +)
If we combine those two equations together it is =
2x + 28 = 48

How do I work this equation and whats the theorem im supposed to use for it?
The length of KH is equal to 7.5 and the length of YB is derived to be 2.05 using the tangent-secant theorem
What is the tangent-secant theoremThis theorem states that if a tangent and a secant are drawn from an external point to a circle, then the square of the length of the tangent segment is equal to the product of the lengths of the secant segment and its external portion.
Given that HN is tangent to the circle, then the triangle HNK is a right triangle and by Pythagoras rule;
KH = √[(4.5)² + 6²]
KH = 7.5
Also, triangle YWM is a right triangle because WY is tangent to the circle so;
YM = √(4² + 9²)
YM = 9.8
WY² = MB × YB {tangent-secant theorem}
4² = (9.8 - YB) × YB {MB = YM - YB}
16 = 9.7YB - YB²
YB² - 9.7YB + 16 = 0
YB = (9.8 ± 5.7)/2 {using the quadratic formula}
YB = 7.75 or YB = 2.05.
In conclusion, the length of KH is equal to 7.5 and the length of YB is derived to be 2.05 using the tangent-secant theorem.

Please help me, I need an answer fast!
Answer:
Equation: m=21(p)
Difference: $5
Step-by-step explanation:
To solve this, we first need to figure out an equation for Company R.
We know that Company S's equation is m=26(p). this means that the amount reimbursed is 26 times the amount of aluminum returned.
210/10=21
Company R's equation is m=21(p). We know this because throughout the table, the amount reimbursed is always 21 times more than the amount of aluminum returned.
Now that we have two equations, we can solve. 26-21=5.
Therefore, the difference between the amount reimbursed per pound is $5. (As long as there is not another variable, this should be the answer for part b)

y=x(3x+1)
Answer:
y = x(3x + 1) is not linear
Step-by-step explanation:
This equation is not linear because it will have an [tex]x^{2}[/tex] which is not linear
y = x(3x + 1)
y = 3[tex]x^{2}[/tex] + x
Helping in the name of Jesus.
Answer:
y=x(3x+1)
Step-by-step explanation:
A nonlinear function is every function whose graph is not a line.
Y=x(3x+1) is a quadratic function, so it's graph is a parabola, not a line.

HELP!! Due in 10 mins
Answer:
The surface area of each half has increased by 60 cm², which is a percentage increase of 31.6% (nearest tenth).
Step-by-step explanation:
The area of a rectangle is the product of its width and length.
If the object is cut in half along the blue line, each piece will increase its surface area by the area of a rectangle that is 6 cm wide and 10 cm long:
[tex]\implies 6 \cdot 10=60\; \sf cm^2[/tex]
Therefore, the surface area of each piece will increase by 60 cm².
If you want to know the increase as a percentage, we first need to calculate the total surface area of the given object by summing the areas of each side.
[tex]\begin{aligned}\implies \textsf{Total\;S.A.}&=(10\cdot 6)+(4 \cdot 6)+4(5\cdot 6)+2(3\cdot 6)+2(10\cdot 5+4 \cdot 5)\\&=60+24+4(30)+2(18)+2(50+20)\\&=60+24+120+36+2(70)\\&=60+24+120+36+140\\&=380\;\sf cm^2\end{aligned}[/tex]
If the total surface area of the object is 380 cm², then the surface area of each half before the object was cut in half is 190 cm².
As we have already determined, the surface area of each half after the object is cut in half increases by 60 cm². Therefore, the total surface area of each piece after the object has been cut in half is:
[tex]\implies 190 + 60 = 250 \; \sf cm^2[/tex]
To calculate how much the surface area of each half has increased, use the percentage increase formula.
[tex]\begin{aligned}\textsf{Percentage increase}&=\sf \dfrac{final\;value-initial\;value}{initial\;value}\\\\&=\dfrac{250-190}{190}\\\\&=0.315789...\\\\&=31.6 \%\; \sf (nearest\;tenth)\end{aligned}[/tex]
Therefore, the surface area of each half has increased by 60 cm², which is a percentage increase of 31.6% (nearest tenth).

The measure of ∠1 is 54 degrees.
Given information:
In a triangle, there are three interior angles 1, 2, and 3.
m∠3 = 55°.
∠2 and 109° are the supplementary angles.
To find ∠1:
The sum of the interior angles of a triangle is always 180 degrees. So we can use this fact to find the measure of ∠1.
m∠2 + m∠3 + m∠1 = 180°
We are given that m∠3 = 55°, and that ∠2 and 109° are supplementary angles, which means that they add up to 180 degrees.
m∠2 + 109° = 180°
Subtracting 109° from both sides, we get:
m∠2 = 71°
Now we can substitute the values we know into the first equation and solve for ∠1:
m∠2 + m∠3 + m∠1 = 180°
71° + 55° + m∠1 = 180°
126° + m∠1 = 180°
Subtracting 126° from both sides, we get:
m∠1 = 54°.

Using the intersecting chords theorem, the value of x in the image given is calculated as: x = 17.1.
What is the Intersecting Chords Theorem?The Intersecting Chords Theorem, states that in a circle, when two chords intersect, the products of the lengths of the line segments of one chord are equal to the products of the lengths of the line segments of the other chord.
Mathematically, it can be represented as (segment of one chord) x (segment of same chord) = (segment of other chord) x (segment of same chord).
Therefore, applying the theorem, we have:
x * 7.5 = 9 * 14.25
7.5x = 128.25
x = 128.25/7.5
x = 17.1
