Answer:
Step-by-step explanation:
F(x)=(5 t^2+t )x to x+3
=5((x+3)^2-x^2)+(x+3-x)
=5(x^2+6x+9-x^2)+3
=5 (6x+9)+3
=30x+48
F'(x)=30
Answer:
x = 13
Step-by-step explanation:
Solve for x:
x + 4 = 17
Subtract 4 from both sides:
x + (4 - 4) = 17 - 4
4 - 4 = 0:
x = 17 - 4
17 - 4 = 13:
Answer: x = 13
Answer:
The average rate of change is 1/4
Step-by-step explanation:
As you can see in the chart, for every four units rightward, the line goes up one unit. That means f(x) has an average rate of change of 1/4.
Answer:
8x/3 + 6
Step-by-step explanation:
2/3 ( 4x+9)
Distribute
2/3 *4x + 2/3 *9
8x/3 + 6
