5x-40 if yo are trying to simplify it
C(b) = 2.75b + 10
This is based of the f(x) = mx + b formula, where m is the slope, x is the variable (or input) and b is the y intercept. In this circumstance the slope is 2.75, so we change m for 2.75. The variable is the amount of books so we change it for b (like it says in the word problem), and and 10 is the starting cost, so it’s the y intercept, so we change b for 10.
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
Answer:
Two spaces left
Step-by-step explanation:
Basically, you have to plot the points on the graph. The first number in the brackets is the x value and the other one is the y value. You would plot -2 on the x-axis. Since the other value is 0, you have to move left two spaces.
U = <-6,1>
-4u = -4*<-6,1>
-4u = <-4*(-6),-4*1>
-4u = <24,-4>
----------------------
v = <-5,2>
2v = 2*<-5,2>
2v = <2*(-5),2*2>
2v = <-10,4>
----------------------
-4u + 2v = <24,-4> + <-10,4>
-4u + 2v = <24+(-10),-4+4>
-4u + 2v = <24-10,-4+4>
-4u + 2v = <14,0>
----------------------
Answer: B) <14,0>
