Evaluate the expression for the given value of the variable

1. 8q + 6; q = 2

Plug in 2 for q in the given expression

8(2) + 6= 22

2. 9 + 4g; g = -3

9 + 4(-3) = 9 - 12 = -3

3. 7x - 7 ; x = 4

7(4) - 7 = 28 -7 = 21

4. 10 - 3.2n; n = 2

10 - 3.2(2) = 10 - 6.4 = 3.6

5. 12p + 4; p = 1.5

12(1.5) + 4= 18  + 4 = 22

6. 5w + 10 = 40

Subtract both sides by 10

5w = 30, now divide both sides by 5

w = 6

7. 4y - 12 = 60

Add both sides by 12

4y = 72

Now divide both sides by 4

y = 18

8. 10k + 5 = 65

Subtract both sides by 5

10k = 60, now divide both sides by 10

k = 6

9. 2b - 15 = 33

Add both sides by 15

2b = 48

Now divide both sides by 2

b = 24

10. 3d + 18 = 21

Subtract both sides by 18

3d = 3, now divide both sides by 3

d= 1

i got 86 for this

hope this !

if you need an explanation just ask

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
