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

ivann1987 [24]

Answer:

64

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 $-8$ .

Jackie has 10 groups of pennies with 3 pennies in each group. Carlos has 5 groups of pennies with 100 pennies in each group. Who

Tcecarenko [31]

Answer=Carlos

If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.

10*3=30 pennies

If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.

5*100=500 pennies

500 pennies is more than 30 pennies, so Carlos has more pennies

Solve for the indicated variable. Include all of your work in your answer. Submit your solution.

levacccp [35]

Answer:

The answer is $L=\frac{A}{W}$

Step-by-step explanation:

In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.

In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.

$A=LW$

We divide each side by "W":

$\frac{A}{W}=\frac{LW}{W}$

We simplify the "W" in the right side:

$\frac{A}{W}=L$

Finally, the solution for "L" is :

$L=\frac{A}{W}$
