x^2 = 16/100
We must solve for x by taking the square root of both sides.
But imagine x^2 = 9. x = 3 is a solution because 3^2 = 9. But x = -3 is also a solution because (-3)^2 = 9. So we need to add the plus and minus sign to account for all of our solutions.
√x^2 = √(16/100)
We square root both sides to remove the exponent 2 on x. Then
x = ±√(16/100)
Then we have to use a Property of Radicals which is √(x/y) = √(x) / √(y).
Then the square root of 16 is 4 and the square root of 100 is 10. 4/10 is 2/5 simplified.
Answer:
(-14,-4)
Step-by-step explanation:
Given the pre-image A=(-7,-2)
If A is dilated with a scale factor of 2
Then the image of A,
A' = (-7,-2) X 2
We multiply each coordinate point by 2
=(-7*2,-2*2)=(-14,-4)
Therefore, the point A' would be: (-14,-4)
Answer:

Step-by-step explanation:
You want x alone on the left side.
x is being multiplied by 3 and by c.
The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.
You must do the same operation to both sides of an equation, so divide both sides by 3c.

Divide both sides by 3c.

Simplify both sides.

8 x 6 = 48 (regularly you’d divide by two but this is on both sides so we’ll leave it)
4 x 10 = 40 / 2 = 20
6 x 4 = 24 / 2 = 12
8 x 4 = 32 / 2 = 16
48 + 20 + 12 + 16 = 96
