Solve by elimination: 5x + 6y = -10; 3x - 2y = -6

Back

(-2, 0)

Front

Solve for a: a = pw; a = p/w; a = w/p; a = w + p

Back

a = w/p

What is a, the starting term, for the function: f(x) = 300(1.16)^x?

Back

300

Front

List the justifications for the first 2 steps used to solve this equation: 8p - 3 + 2(p + 5) = 10p - 17; 8p - 3 + 2p + 10 = 10p - 17; 8p + 2p - 3 + 10 = 10p - 17

Distributive Property & Commutative Property

Front

What is the first step in solving the following equation for v: 7v + 15 = 4(5v + 7)?

Back

Distribute 4: 7v + 15 = 20v + 28

Front

What is the Distributive Property?

Back

a(b + c) = ab + ac

Front

What is the Commutative Property of Addition?

Back

a + b = b + a

Front

What is the Associative Property of Addition?

Back

(a + b) + c = a + (b + c)

Front

What is the Zero Product Property?

Back

If ab = 0, then a = 0 or b = 0.
