Answer:

B

Step-by-step explanation:

To find the slope m use any 2 ordered pairs from the table.

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)

m = \frac{-1-11}{2+4} = \frac{-12}{6} = - 2 → B

Y = 3x + 15<br> 3x + 3y = 9
Zina [86]

Answer:

\Large\boxed{x=-3}\Large\boxed{y=6}

Step-by-step explanation:

<u>Given the system of equations</u>

1)~y=3x+15

2)~3x+3y=9

<u>Divide 3 on both sides of the 2) equation</u>

3x+3y=9

3x\div3+3y\div3=9\div3

x+y=3

<u>Current system</u>

1)~y=3x+15

2)~x+y=3

<u>Substitute 1) equation into the 2) equation</u>

x+(3x+15)=3

<u>Combine like terms</u>

x+3x+15=3

4x+15=3

<u>Subtract 15 on both sides</u>

4x+15-15=3-15

4x=-12

<u>Divide 4 on both sides</u>

4x\div4=-12\div4

\Large\boxed{x=-3}

<u>Substitute the x value into one of the equations to find the y value</u>

y=3x+15

y=3(-3)+15

y=-9+15

\Large\boxed{y=6}

Hope this helps!! :)

Pls help find x in both
RUDIKE [14]

Answer:

Step-by-step explanation:

In similar triangles, corresponding sides are in same ratio

\frac{28}{24} = \frac{3x-9}{x +8}\\\\\frac{7}{6}=\frac{3x-9}{x+8}\\

Cross multiply,

7*(x + 8) = 6*(3x -9 )

7x + 7*8 = 6*3x - 6*9

7x +  56   = 18x - 54

          56 = 18x - 7x -54

          56 = 11x - 54

         11x - 54 = 56

               11x  = 56 +54

                11x = 110

               x = 110 /11

x = 10

PR = 3x -9

     = 30 - 9

PR = 21
