y= -10x + 5.5 ....... I might be wrong, sorry
Answer:
y = 0.55x + 5.5
Step-by-step explanation:
Start with y = mx + b. We already know that b = 5.5, so now we have:
y = mx + 5.5. Next, subst. -10 for x and 0 for y, obtaining 0 = m(-10) + 5.5. Then 10 m = 5.5, and m = 5.5/10, or 0.55.
Thus, the equation is y = 0.55x + 5.5.

60 divided by 3 = 20
Domain: x is greater than or equal to 7
Range: y is greater than or equal to 9
You are solving for the height. Use the formula:
c² - b² = a² in which c = hypotenuse
(13)² - (5)² = a²
Simplify
169 - 25 = a²
144 = a²
Isolate the a. Root both sides
√144 = √a²
a = √144
a = √(12 x 12)
a = 12
C) 12 feet is your answer
