Answer:
Step-by-step explanation:
y - y₁ = m ( x - x₁)
y - 5 = - 3 (x - 12)
y - 5 = -3x + 36
3x + y = 36 + 5
3x + y = 41
y = -3x + 41
Since they are right triangles use Pythagorean Theorem.
a^2 + b^2 = c^2 where c is the hypotenuse.
a. 12^2 + b^2 = 13^2
144 + b^2 = 169
subtract 144 from both sides
b^2 = 25
take the square root of both sides
t = 5 This is also know as a Pythagorean Triple 5-12-13
b. a^2 + 9^2 = 12^2
a^2 + 81 = 144
subtract 81 from both sides
a^2 = 63
take the square root of both sides
a = √63
a = √(9 * 7)
a = 3√7
c. 6^2 + 9^2 = c^2
36 + 81 = c^2
117 = c^2
take the square root of each side
c = √117
c = √(9*13)
x = 3√13
I manage to check the graph from other source. I think the answer will be "<span>The slope is 0.40 and it represents the cost per mile traveled."
