the amount of time of the two trips is a proportional relationship
<h3>What is proportional relationship?</h3>
mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.
<u>solution:</u>
Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph
while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph
since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

Step-by-step explanation:
to find the y- intercept substitute x = 0 into f(x)
f(0) = (0 - 11)(0 - 2) = - 11 × - 2 = 22 → (0, 22 )
Hello :
<span>F(x) = x² + 3x - 2
</span><span>F(-1) = (-1)²+3(-1) -2
</span>F(-1) = 1 - 3 -2 =1 - 5
F(-1) = -4
