Answer:For a positive value k, the graph of y=kf(x) is obtained from the graph of y=f(x) by scaling in the vertical direction. In coordinates, if (x0,y0) is on the graph of y=f(x), then that point moves to (x0,ky0) on the graph of y=kf(x). Any point on the x-axis remains fixed (as then y=0). When k>1, the graph is stretched vertically (away from the x-axis), while if 0<k<1, the graph is compressed vertically (toward the x-axis).
Another way to think about this: The graph of y=kf(x) is exactly the same as the graph of y=f(x) if the y-axis is scaled so that 1 is relabeled k, 2↦2k, −1↦−k, etc.

Answer:
They sold 67.50 in total
Step-by-step explanation:
If each of them sold 15 boxes for 2.25 then both of them got 33.75 each then you add it and that gives you 67.50
Answer:
Y = 3
X = 2
Step-by-step explanation:
(6x2) = 12
(8x3) = 24
12 + 24 = 36
(6x2) = 12
(5x3) = 15
12 + 15 = 27
Answer:
x = positive or negative
Step-by-step explanation:
Because it is impossible to simplify this with rational numbers, it is needed to use the quadratic formula. When doing this, you will find that x = positive or negative . Hope this helps! :)
