Question

Use the equation y + 4 = 3x to fill in the missing values in the table below. (Type in the numbers for your answers, do not spell the number out, or it will count it wrong.)

x y
-7
8
0
-34

Answer 1

To fill in the missing values in the table, we can substitute the given values of x into the equation y + 4 = 3x and solve for y.

For x = -7:
y + 4 = 3(-7)
y + 4 = -21
y = -21 - 4
y = -25

For x = 8:
y + 4 = 3(8)
y + 4 = 24
y = 24 - 4
y = 20

For x = 0:
y + 4 = 3(0)
y + 4 = 0
y = 0 - 4
y = -4

For x = -34:
y + 4 = 3(-34)
y + 4 = -102
y = -102 - 4
y = -106

Complete table:
x y
-7 -25
8 20
0 -4
-34 -106
