Answer:
Step-by-step explanation:
Try and become familiar with a program like Desmos. It will do wonderful things for you.
I have graphed
Red: y = -2x + 5 (The 5 is the y intercept. For this question it could be anything.
Blue: y = - 4x + 5 Same note as above.
Answer:
7
232
Step-by-step explanation:
First
Normally the average of something is total something over total time. I'll do it that way and see what happens.
The total time is ( 4 - 2) = 2 hours.
f(x) = 2^4 - 2 = 14
Change = 14/2 = 7 per hour.
Second
Average = Increase / time.
10000 (1.02)^10 - 10000 * (1.02)^5
10000*1.22 - 10000*1.104
12,200 - 11040
1160
The average per year = 1160 / 5 = 232
Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
4+28= 32
Think of it as you have 28 apples and someone gave you 4 how many would you have
The answer is D -2x^3-16x^2-10x
