Answer:

f(x) = 15

Step-by-step explanation:

"If f(x)= 5x + 40, what is f(x) when x = -5?"

Substitute x for -5:

f(x) = 5x + 40

f(x) = 5(-5) + 40

f(x) = -25 + 40

f(x) = 15

Answer:

\Huge\boxed{131.88}

Step-by-step explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88

So we can conclude that the circumference of the circle is 131.88 inches

Which function in vertex form is equivalent to f(x) = x² + x +1?
mylen [45]

Answer:

\left( x+\frac{1}{2} \right)^{2}  + \frac{3}{4}

Step-by-step explanation:

NOTE :

x^2+ax=\left( x+\frac{a}{2} \right)^{2}  -\left( \frac{a}{2} \right)^{2}

………………………………………

f(x) = x² + x +1

     =x^{2}+2\times \frac{x}{2} +1

     =\left( x+\frac{1}{2} \right)^{2}  -\left( \frac{1}{2} \right)^{2}  +1

     =\left( x+\frac{1}{2} \right)^{2}  - \frac{1}{4}+1

     =\left( x+\frac{1}{2} \right)^{2}  + \frac{3}{4}
