Answer:

Step-by-step ef(x)=-2x+5……i

and f(-3x)=?

let x=-3x so that

-2x+5=-3x

x=5

substitutinx x into… i

f(x)=-10+5=-5

f(5)=-5………ii

now f(–3x)=f(-15)

scrutinizing… ii ,we can propose that

f(-15)=15.

Thus f(-3x)=15xplanation:

f times x would equal to fx=2x+5 and i think we move the x move to the other side which makes it f=3x+5 and then we plug this equal into f(3x) (i think) which makes it f(3x+f=3x+5)

Sixteen scholars have volunteered to stay after school to help set up for the school musical. The musical director plans to orde

lapo4ka [179]

The director would have to pay $40.47.

If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16

8+8=16

If all of them eat another .5 slice, adding up the halves would equal 8

.5 x 16 = 8

In total, the director would have to buy three pizzas which equals up to our total of $40.47
