The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).

ivann1987 [24]

Answer:

Step-by-step explanation:

$g(f(-1))$ can be found by first finding $f(-1)$ then taking that result and putting it into the function $g$ .

$f(-1)$ means we are going to take the expression $x-7$ and evaluate it for $x=-1$ :

$-1-7$

$-8$

So $f(-1)=-8$ .

So we have this so far:

$g(f(-1))=g(-8)=(-8)^2=64$ .

$g(-8)$ was found by replacing $x$ in $x^2$ with $-8$ .

What is the slope of these lines? What is the equation of these lines?

Mashcka [7]

For both lines the slope is 5/2 or 2.5.
Since the y-intercept is zero for both, both the equations are:
y=2.5x
Or
y=5/2x

If the original quantity is 15 and the new quantity is 19, estimate the percent change.

eduard

To calculate percent change:
(difference between original and new)/original * 100
(19-15)/15 * 100 =
4/15 * 100 = 26.7 % increase

Simplify the radical expression (5+√3)(5-√3) a. 16 b. 22 c. 25+10√3 d. 16+10√3

Alja [10]

B is the correct answer

$(5 + \sqrt{3} )(5 - \sqrt{3) } \\ = 25 - \sqrt{3 {}^{2} } = 25 - 3 = 22$

good luck
