F(x) = 4x² + 5
f(2) = 4(2)² + 5
f(2) = 4(4) + 5
f(2) = 16 + 5
f(2) = 21

If you rearrange the equation so w is the independent variable, then what is u? -2u+6w=9

Serjik [45]

Answer:

u = - ( 9-6w)/2

Step-by-step explanation:

to evaluate for u in the expression -2u+6w=9 is simply to look for a way such that we would express u in terms of w and other variables.

solution

-2u+6w=9

-2u = 9 - 6w

divide both sides by the coefficient of u which is -2

-2u/u = 9 - 6w/-2

u = - ( 9-6w)/2

therefore the value of u when rearranged in the equation -2u+6w=9 is evaluated to be equals to

u = - ( 9-6w)/2

What is the pattern in the values as the exponents increase?

nirvana33 [79]

Answer:

"Multiply the previous value by 2"

Step-by-step explanation:

Let's check the first 2 terms for all the answer choices.

1. Add $\frac{1}{16}$ to the previous value:

$\frac{1}{32}+\frac{1}{16}=\frac{3}{32}$

Doesn't match.

2. Subtract $\frac{1}{16}$ from the previous value:

$\frac{1}{32}-\frac{1}{16}=-\frac{1}{32}$

Doesn't match.

3. Divide the previous value by 2:

$\frac{\frac{1}{32}}{2}\\=\frac{1}{32}*\frac{1}{2}=\frac{1}{64}$

Doesn't match.

4. Multiply the previous value by 2:

$\frac{1}{32}*2=\frac{2}{32}=\frac{1}{16}$

DOES WORK!

Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
