OR

correct to 2 decimal places
Answer:
Step-by-step explanation:
Average rate of change within an interval is the slope of the endpoints.
The endpoints are:
The slope is
- (3 - 6)/(0 - (-1)) = - 3/1 = - 3
Correct choice is C
Answer:
Step-by-step explanation:
4^-3
=1/4^3
=1/64
1) 4x + 3(x-9) = 19
or, 4x + 3x - 27 = 19
or, 7x = 19+27
or, 7x = 46
or, x = 46/7
◆ x = 6.57
2) 2(x-4) + 5x = 3
or, 2x - 8 + 5x = 3
or, 7x = 3+8
or, x = 11/7
◆ x = 1.57
3) 60 = 8y - 3(y-10)
or, 60 = 8y - 3y + 30
or, 60 - 30 = 5y
or, y = 30/5
◆ y = 6
4) 40 + 3c = 3 + 9(c-2)
or, 40 + 3c = 3 + 9c - 18
or, 40 + 3c = 9c - 15
or, 9c - 3c = 40 + 15
or, 6c = 55
◆ c = 9.166
I hope you understand..
Thank you...♥♥
