What is the average rate of change from x = 0 to x = 5?
-80
-40
-8
-2
what is the average rate of change from x = 10 to x = 15?
-8
-4
-3
-2
the first question is -8.
the second question is -2.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

i dont know if you cant find a way its best to actually add all of them start from 105 tho
