You have to find how many kids are in eighth grade so you would multiply 34x6 and get 204 then you decide that by 1/4 and you get 51

Y = -9x - 2; (4, -37)

Karo-lina-s [1.5K]

Answer:

B. No the ordered pair does not satisfy the equation

Step-by-step explanation:

y = -9x - 2

Substitute the point in and see if it is true

-37 = -9(4) -2

-37 = -36 -2

-37 = -38

This is not true so the point is not a solution

I need with these problems

Answer:

1. $\frac{5}{6}$

3. $\frac{7}{0}$ (undefined slope)

5. $-\frac{7}{4}$

7. $24$

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}$

3. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0}$ (undefined slope)

5. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}$

7. r = $\frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24$

Hope this helps!

What is the equation of a circle with radius 23 and whose center is the intersection of the lines y=2x+1 and 4x+y=13?

Novay_Z [31]

The center is (2,5) and the equation is a(x-2)^2 + (y-5)^2= 23^2
A(x-2)^2 +(y-5)^2=529
