52+4y=12

We move all terms to the left:

52+4y-(12)=0

We add all the numbers together, and all the variables

4y+40=0

We move all terms containing y to the left, all other terms to the right

4y=-40

y=-40/4

y=-10

_______________________________________________________

3.1-3y=18

We move all terms to the left:

3.1-3y-(18)=0

We add all the numbers together, and all the variables

-3y-14.9=0

We move all terms containing y to the left, all other terms to the right

-3y=14.9

y=14.9/-3

y=-4+2.9/3

If f(x) = integral of 1/ (sqrt of t^3 +2)dt, then f'1 = ?
mihalych1998 [28]
Differentiating an integral removes the integral.

f(x) = integral of dt/sqrt(t^3 + 2)
f'(x) = 1/sqrt(x^3 + 2)
f'(1) = 1/sqrt(1^3 + 2)
f'(1) = 1/sqrt(3) = sqrt(3)/3.

Solve 80% of x = 100 or 0.8x = 100
suter [353]

Answer:

125

Step-by-step explanation:

divide both sides of the equation by 0.8

0.8÷0.8=0.8÷100

any expression divided by 1 is itself

x=100÷0.8

divide the numbers

100÷0.8=125

lapo4ka [179]
Most likely B because one pound is equal to 6 dollars. So i think it would be x= 1 and y= 6

So put the x as the dom and 6 as the num?
