Answer: x=-6
Step-by-step explanation:
Given
2x + 8 = -4
Subtract 8 on both sides
2x + 8 - 8 = -4 - 8
2x = -12
Divide 2 on both sides
2x / 2 = -12 / 2
x = -6
NOTE: I assume the questions "solve for c" actually means "solve for x"
Hope this helps!! :)
Please let me know if you have any questions
the number is x
4x+3 = 5+x
subtract x from both sides
3x+3 = 5
subtract 3 from both sides
3x = 2
divide both sides by 3
x = 2/3
Answer:

Step-by-step explanation:
Answer:
1) -15/4
2) -15/2
Step-by-step explanation:
1) Let u=4t. Then the limits become u=4(0)=0 and u=4(4)=16. Also du=4 dt upon differentiating the equation.
So the integral can be written as
Integral( 1/4 f(u) , u=0 to u=16)
We are given Integral( f(u) , u=0 to u=16) is -15. So a fourth of that is our answer for the first question.
2) Let u=t^2. Then the limits become u=(0)^2=0 and u=(4)^2=16. Also upon differentiating we obtain equation du =2 t dt.
So the integral becomes
Integral( 1/2 f(u) , u=0 to u=16).
We are given Integral( f(u) , u=0 to u=16) is -15. So a half of that is our answer for the second question.
