Answer:
B, C
Step-by-step explanation:
Both these intervals are where the graph is increasing.
The amount increased 4% from last year.
Step-by-step explanation:
Given,
Average cost last year = $625
Average cost this year = $650
Increase amount = Average cost last year - Average cost this year
Increase amount = 650 - 625 = $25
Percent increase = 

The amount increased 4% from last year.

Answer:
5(n-4)(n+4)
Step-by-step explanation:
given that
5n²-80
first we take common factor.
5(n²-16)
now we use the sum product pattern
5(n²+4n-4n-16)
We take common factor from pairs
5(n(n+4)-4(n+4))
5(n+4)(n-4).

Solving for A.
STEP 1 ● Add -bx to both sides.
ax^2 + bx + c + -bx = 0 + -bx
ax^2 + c = -bx
STEP 2 ● Add -c to both sides.
ax^2 + c + -c = -bx + -c
ax^2 = -bx -c
STEP 3 ● Divide both sides by x^2
ax^2 / x^2 = -bx -c / x^2
a = -bx -c / x^2
ANSWER ● a = -bx -c / x^2

Answer:
Step-by-step explanation:
Sum of exterior angles of any polygon =360°
Sum of exterior angles of polygon = 360°
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360
m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4 = 360 {Combine like terms}
15m + 15 = 360 {Subtract 15 from both sides}
15m = 360 - 15
15m = 345 {Divide both sides by 15}
m = 345/15
m = 23
m + 5 = 23 + 5 = 28°
2m + 3 = 2*23 + 3 = 46 + 3 = 49°
3m + 2 = 3*23 + 2 = 69 + 2 = 71°
4m + 1 = 4*23 + 1 = 92 + 1 = 93°
5m + 4 = 5*23 + 4 = 115 + 4 = 119°
