7). Equation incomplete

8). y=3x+23

Step-by-step explanation:

1).

3x-y=5

Subtract 3x from both sides

-y=5-3x

Multiply both sides by -1

y= -5+3x

2).

y+7= -2(x+3)

y+7= -2x-6

Subtract 7 from both sides

y= -2x-13

3).

y= -10-6(x-2)

y=  -10-6x+12

y= -6x+2

4).

3x=12-3y

Add 3y to both sides

3x+3y=12

Subtract 3x from both sides

3y=12-3x

Divide both sides by 3

y= -x+4

5).

-4x-7y=0

Add 4x to both sides

-7y= -4x+0

Multiply both sides by -1

7y= 4x

Divide both sides by 7

y≈ 0.57x

6).

4x-2y=18

Subtract 4x from both sides

-2y= -4x+18

Multiply both sides by -1

2y=4x-18

Divide both sides by 2

y=2x-9

7).

y= 5-

Equation is incomplete.

8).

y-2=3(x+7)

y-2=3x+21

Add 2 to both sides

y=3x+23

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
