Leannie bought 5 of Dr. Mumin’s book and 3 of Dan Moyer’s book
Answer: 2d
Step-by-step explanation:
You multiply the cost by the amount d, to find the total cost. Since it wants an expression, there is no equal sign.
Answer:
One solution
Step-by-step explanation:
We know there is only one solution because the lines do not have the same slope, nor are they the exact same line.
So we know they must have just one solution.
Best of luck

Derivative Property [Multiplied Constant]:
Basic Power Rule:
- f(x) = cxⁿ
- f’(x) = c·nxⁿ⁻¹
Derivative Rule [Product Rule]: ![\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Bd%7D%7Bdx%7D%20%5Bf%28x%29g%28x%29%5D%3Df%27%28x%29g%28x%29%20%2B%20g%27%28x%29f%28x%29)

Topic: AP Calculus AB/BC (Calculus I/I + II)
Unit: Differentiation
I believe that the last one is true
because the linear equations are
y=ax+b
which means that the point of y-axis is on one side and the slope, point on x-axis and y-intercept are on the other side
good luck
