Answer:
y=770-55x --- given
y - 770 = 770 - 55x - 770 ----subtraction property of equality
y = -55x + 770 ---Simplification
y-770/-55 = -55x/-55 --- Division property of equality
-y-770/55=x---Simplification
Step-by-step explanation:
Answer: 9 inches.
Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.
