Answer:

15x^4-5x^2+1

Step-by-step explanation:

g(x)=5x^2-1 and f(x)=3x^2-x+2

f(g(x))would mean that g(x) would be x in f(x).

So f(g(x) would be 15x^4-3-5x^2+1+2

simplified would be 15x^4-5x^2+1

Xavier and Ava are employees for a company. Xavier is making a salary of $42,700.

MrMuchimi

$62,342 is the salary earned by Ava.

Step-by-step explanation:

step 1 :

Xavier's salary = $42,700

step 2 :

Ava's salary = 46% higher than Xavier salary.

= 100% of Xavier salary + 46% of Xavier salary

= 146% of Xavier salary

step 3 :

Ava is earning a salary = (146/100) $\times$ 42,700

= 146 $\times$ 427

= 62,342

∴ Ava is earning a salary of $62,342.

Aleksandr [31]

-1 = 3x - 7
Add +7 to each side
6 = 3x
Divide each side by 3
X = 2

f(-1) = 3 * 2 - 7
