Answer:
I=V/R
Step-by-step explanation:
In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.

Step-by-step explanation:
Answer:
A. Dividing both sides by 4 isolates the variable.
Step-by-step explanation:
In order to solve for x, you need to get it all by itself. Dividing both sides of the equation by 4 gives you 8 on the right side and only x on the left side , therefore the variable is isolated. (This uses the Division Property of Equality.)
The inverse of the function given will be:
f(x)=(x-7)^(1/3)
to get the inverse we make x the subject
let f(x)=y=(x-7)^(1/3)
y=(x-7)^(1/3)
getting the cube of both sides we have:
y³=[(x-7)^(1/3)]³
y³=x-7
thus
x=y³+7
next we replace y by x and x with f^-1(x)
thus the inverse will be:
f^-1(x)=x³+7
Answer:
Step-by-step explanation:
Okay, so you need to create an equation which shows that twice the sum of a number (n) and 7 is 3 times that number. So you need twice the sum of n + 7 and that will equal 3 times n.
2(n + 7) = 3n
Now, multiply
2n + 14 = 3n
2n + 14 -2n = 3n - 2n
14 = n
So the number is 14. Now you can check your answer
2(14 + 7) = 3(14)
2x21 = 42
42 = 42
