Hey There
Correct answer: 13
Why? To find this out you need to add 4 to 9 to figure it out
have a good day
Answer:
x = 50
Step-by-step explanation:
the angle next to x is 65 so the angle on the oposite side will also be 65.
a straight line = 180
so 180 - 65 -65 = 50
x = 50
The answer should be a total of 3
Answer: 4
Step-by-step explanation:8 + 9 = 17 you take what he paid 13 and subtract 13 from 17 and you get 4. 4 is how many dollars off he got.
Rate of change is like slope. Change in y/ change in x
First we have to solve for the y.
x^2 -3x -4 when x = 7
7^2 -3(7)-4= 24 (7,24)
x^2-3x-4 when x=10
10^2-3(10)-4= 66 (10,66)
(66-24)/(10-7)
42/3 = 14
