22-23 S1 Finals Review #2

What math operation are we doing with a COEFFICIENT and a VARIABLE,

for example, -4h?

• We are dividing h by -4

• We are multiplying -4 and h.

• We are subtracting 4 from h.

SOLVE for the variable:

- 5 = w + 15

• w = - 20

• w = 10

• w = -10

SOLVE for the variable:

- 9x = -63

• x = - 54

• x = 7

• x = -7

• x = -21

• x = 10

• x = 21

SOLVE for the variable:

- 3x - 8 = 10

• x = 21

• x = 15

• x = -6

• x = 16

• x = 40

• x = 14

Like terms have the same _____ and the same _____

or are just numbers (constants).

• variables and numbers

• signs and numbers
• variables and exponents

x² can be combined with x

• True, they are both x's

• False, they do not have the same exponent.

What are the LIKE TERMS?

4x³ - x² + 5 + x - 7

• 4x³, -x², and x

• 5 and -7

• -x² and x

Simplify the expression: 7x + x

• 8x

• 7x

• 7x²
