Answer:
Slope Intercept Form Equation: y = mx + b, or sometimes y = mx + c, m = slope (the amount of rise over run of the line) b= y-axis intercept ( where the line crosses over the y-axis) To calculate the slope intercept form equation from two coordinates.
Step-by-step explanation:
The right answer will be A
FOR THE FIRST PROBLEM:
Differentiating p^2 + 2q^2 = 1100 with respect to time => 2p(dp/dt) + 4q(dq/dt) = 0
<span>dp/dt = -2q/p(dq/dt) </span>
<span>R = pq </span>
<span>dR/dt = p(dq/dt) + q(dp/dt) = -p²/2q(dp/dt) + q(dp/dt) = (2q² - 1100)/2q * (dp/dt) + q(dp/dt) </span>
<span>A = (2q - 550/q)

This line crosses the point (4,5)so we can make an equation to find the slope:

About 38 cars. 300/8= 37.5 cars. There is no such thing as 0.5 of a car so round up to the nearest whole number.
