Answer:
When there are numbers like that next to the radical it means multiply. like this: 2<u>√9</u>. You would first figure out the square root. <u>Square root of 9</u> is 3. 2 times 3 is 6.
After you figure out those problems, you just need to put the number, x, and y in an equation with 2 unknowns.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x))
= f(x²)
= 2(x²) - 4 = 2x² - 4

When you have this type of problem, you need to combine the like-terms and isolate the variable.
3x + 122 = 22x - 11
Add 11 to both sides to get rid of it
3x + 122 + 11 = 22x - 11 + 11 (-11 + 11=0)
3x + 133 = 22x
Then you would bring the 3x to the other side, so subtract 3x from both sides
3x + 133 = 22x
-3x -3x
133 = 22x - 3x
133 = 19x
Then divide both sides by 19 to isolate x
133/19 = 19x/19
133/19 = 7, so x = 7
Hope this helps!!
