Answer:

{y,x} = {-6,-2}

Step-by-step explanation:

/ Solve equation [2] for the variable y

[2] y = 2x - 2

// Plug this in for variable y in equation [1]

[1] (2x-2) - x = -4

[1] x = -2

// Solve equation [1] for the variable x

[1] x = - 2

// By now we know this much :

y = 2x-2

x = -2

// Use the x value to solve for y

y = 2(-2)-2 = -6

For this you count rise over run aka how many up divided by how many over starting from 0. here it’s 7 up and 3.5 side, 7 divided by 3.5 is 2 and the line is going down so it’s negative 2 (D)

Suppose j varies jointly with g and v, and j=2 when g=4 and v=3. <br> Find j when g=8 and v=9.

vladimir2022 [97]

Answer:

$j=12$

Step-by-step explanation:

we know that

In a join variation, If j varies jointly with respect to g and v, the equation will be of the form $j = kgv$

where k is a constant

step 1

Find the value of k

we have

j=2,g=4,v=3

substitute and solve for k

$2 = k(4)(3)$

$2 = 12k$

$k=\frac{1}{6}$

The equation is equal to

$j=\frac{1}{6}gv$

step 2

Find the value of j when g=8,v=9

substitute the values in the equation and solve for j

$j=\frac{1}{6}(8)(9)$

$j=12$
