The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
Formula for finding percent change (increase or decrease) is amount of the change divided by the original amount.
Here, the amount of the change is 50 and the original amount is 250.
50/250= 0.2
Multiply by 100 to get percent.
20% decrease (because budget went down)
Graph the line y=5x. Then graph the line y=x. Then look at them and describe in what ways they are the same or different.
Answer:
20 x
Step-by-step explanation:
i hope that is it
Answer:
yes
Step-by-step explanation:
y <= -4x + 12
(2,4) 4 <= -4*2 + 12 4<= 4 is true
