Answer:

-11

Step-by-step explanation:

There is enough information to put the equation in point slope form.

[tex]y-y_1=m(x-x_1)[/tex]

We are given the point of (-5,4) and the slope of -3.

[tex]y-y_1=m(x-x_1)\rightarrow \boxed{y-4=-3(x+5)}[/tex]

Now, we can take the point slope equation and convert it into slope intercept form.

[tex]y-4=-3(x+5)\\\\\left \{ {{-3*x=-3x} \atop {-3*5=-15}} \right.\\\\ y-4=-3x-15\\\\y-4+4=-3x-15+4\\\\\boxed{y=-3x-11}[/tex]

The y-intercept should be -11.

Answer:

B

Step-by-step explanation:

2 should be distributed as 2y + 12; y = 6

Step-by-step explanation:

The equation is...

[tex]2(y+6)=4y[/tex]

First, we need to distribute the 2 to the numbers in the parentheses. We will multiply them both by 2.

[tex]2y+12=4y[/tex]

Now we can subtract 2y from both sides. On the left it will cancel and on the right we will be left with 2y.

[tex]12=2y[/tex]

Now we can just divide and...

y = 6

Answer:

22.5

Step-by-step explanation:

Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:

13.5 / 0.6 = 22.5

22.5 x 0.6 = 13.5

Answer:

In the problem, 60% of 22.5 is 13.5.

Step-by-step explanation:

The first thing we have to do is know what the problem is asking us to find. In the problem, we are asked to find the number that 13.5 is 60% of. In order to find this number, we have to divide. We are going to divide 13.5 by 60%. 60% can be turned into decimal form which is 0.6.

13.5 ÷ 0.6 = 22.5

So, the number that 13.5 is 60% of is 22.5.

Answer:

x = 3/4

Step-by-step explanation:

Simply add 1/4 to both sides of the equation to isolate x and to get your answer.

x = 1/4 + 1/2

x = 1/4 + 2/4

x = 3/4 or 0.75

Answer:

x = 3/4

Step-by-step explanation:

Answer:

x=-2

y=-10

Step-by-step explanation:

x+y=-12

x-y=8

x=y+8

(y+8)+y=-12

2y+8=-12

2y=-20

y=-10

x+10=8

x=-2

Answer:

[tex]x = - 2 \\ y = - 10[/tex]

Step-by-step explanation:

[tex]x + y = - 12 \\ x - y = 8[/tex]

[tex]x + y + (x - y) = - 12 + 8 \\ x + y + x - y = - 4 \\ 2x = - 4 \\ \frac{2x}{2} = \frac{ - 4}{2} \\ x = - 2[/tex]

[tex]x + y = - 12 \\ - 2 + y = - 12 \\ y = - 12 + 2 \\ y = - 10[/tex]

Answer:

Interpreting as: x+3x+2=3+1x

Input:

x + 3 x + 2 = 3 + 1 x

Result:

4 x + 2 = x + 3

We want to find the solution set of the equation:

x + 3x + 2 = 3 + 1/x

The solution set is { (1 + √17)/8, (1 - √17)/8)}

To find this, we just need to solve the equation for x.

We start with:

x + 3x + 2 = 3 + 1/x

We simplify this to:

(x + 3x) + 2 = 3 + 1/x

4x + 2 = 3 + 1/x

4x + 2 - 3 - 1/x = 0

4x - 1 - 1/x = 0

Then we multiply by x in both sides to get:

4x^2 - x - 1 = 0

This is just a quadratic equation, the solutions are given by Bhaskara's equation.

[tex]x = \frac{-(-1) \pm \sqrt{(-1)^2 - 4*4*(-1)} }{2*4} \\\\x = \frac{1 \pm \sqrt{17} }{8}[/tex]

Then the solution set is: { (1 + √17)/8, (1 - √17)/8)}

Answer:

P (X≤1) = 0.000

Step-by-step explanation:

Data given:

p = 79% = 0.79

q = 1 - 0.79 = 0.21

n = 16

P (no more than 1 in 16 adults) = P (X≤1)

P (X≤1) = P (X=0) + P (X=1)

We can find the probability by using binomial functions:

[tex]P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}[/tex]

P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶

Use calculator to solve:

P(X=0) = 0.000000000798

P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵

Use calculator to solve:

P(X=1) = 0.000000034506

P (X≤1) = P (X=0) + P (X=1)

P (X≤1) = 0.000000000798 + 0.000000034506

P (X≤1) = 0.00000003530

P (X≤1) = 0.000

As 1 is a very low number, its probability is very small

[tex]x^2 + (y - 4)^2 = \dfrac{25}{9}[/tex]

Step-by-step explanation:

The equation of a circle with center at (h, k) and radius r is

[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]

You have center (0, 4).

We get:

[tex] (x - 0)^2 + (y - 4)^2 = r^2 [/tex]

[tex] x^2 + (y - 4)^2 = r^2 [/tex]

To find the radius, we use the distance formula to find the distance from the center of the circle to the given point on the circle.

[tex] r = d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] r = \sqrt{(\dfrac{4}{3} - 0)^2 + (5 - 4)^2} [/tex]

[tex] r = \sqrt{(\dfrac{4}{3})^2 + 1^2} [/tex]

[tex] r = \sqrt{\dfrac{16}{9} + \dfrac{9}{9}} [/tex]

[tex] r = \sqrt{\dfrac{25}{9}} [/tex]

We need r^2 in the equation of the circle, so

[tex] r^2 = \dfrac{25}{9} [/tex]

The equation of the circle is

[tex]x^2 + (y - 4)^2 = \dfrac{25}{9}[/tex]

w = 89°

Step-by-step explanation:

For this triangle, we have to get the supplementary angle of 122°. 180° - 122° is 58°. We then take 58° and add it to 33°. That is 91°. To find w, we subtract 91° from 180°. That gives us 89°.

Step-by-step explanation:

Answer: there are 36 tourists.

Step-by-step explanation:

Ok, we have two integer numbers:

T, the number of tourists and S, the number of seats.

Such that, if we divide the tourists into groups of 4 and in groups of 6, we end with no empty seats.

Knowing that the number S must be an integer, and when we divide T into groups of 4 and 6 we end with no empty seats, this means that T can be divided by 4 and by 6.

This means that T is a common multiple of 4 and 6

Now, we also know that 25 < T < 45.

Then let's see which ones are the multiples of 4 between 25 and 45.

4*7 = 28

4*8 = 32

4*9 = 36

4*10 = 40

4*11 = 44.

Now, the multiples of 6 in that range are:

6*5 = 30

6*6 = 36

6*7 = 42.

You can see that 36 is a common multiple, other way to see it is:

4*9 = (2*2)*(3*3) = 2*2*3*3 = (2*3)*(2*3) = 6*6

So the numer of tourist must be 36.

The area of the triangle RST is 3 square units if the triangle RST has points (-3, 2), (3, 2), and (-1, 1). An altitude is drawn from point T to point U at (-1, 2).

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have:

Triangle RST has points (-3, 2), (3, 2), and (-1, 1).

We are assuming the coordinate for point R is (-3, 2)

S(3, 2)

T(-1, 1)

An altitude is drawn from point T to point U at (-1, 2).

From the distance formula, we can find the distance between R and S and distance between TU.

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

h = 1 units

b = 6 units

Area of triangle RST = (1/2)(6×1) = 3 square units

Thus, the area of the triangle RST is 3 square units if the triangle RST has points (-3, 2), (3, 2), and (-1, 1). An altitude is drawn from point T to point U at (-1, 2).
