G(x) = 2x + 1 and f(x) = g(x) - 3, what is f(2)?

 2

Step-by-step explanation:

We put the g(x) in the f(x) function, we get f(x) = 2x + 1 -3. We simplified it, so we get f(x) = 2x - 2.

And we plug in 2 for x to solve for f(2).

f(x) = 2x - 2

f(2) = 2(2) - 2

f(2) = 4 - 2

f(2) = 2

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
