Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b =
= 60
I am torn between B and D because increased means add, but I am going to go with B 1 - 3n. I choose B because in the D option it decreases not increases.
So the answer is B.) 1 - 3n

The equation that represents a proportional relationship is m = -0.5b
<h3>
Proportional relationship</h3>
Two variables are said to be proportional if an increase in one variable leads to an increase in other variable and a decrease in one variable leads to an decrease in other variable.
Given that m ∝ b
m = kb
When m = 3, b = -6, hence:
3 = -6k
k = -0.5
m = -0.5b
