Irina-Kira [14]

Answer:

24 customers will not use coupons.

Step-by-step explanation:

Number of customers who use coupons = 9

Number of customers who don't use coupons = x

Ratio of customers who use coupons to customers who don't use coupons = 6:16

$=\frac{6}{16}$

$\frac{9}{x}=\frac{6}{16}$

$x=\frac{9\times 16}{6}=24$

If q(x)=7x^2-1 find q(-9)

liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:

$q(x)=7x^{2} -1$

$q(-9)=7(-9)^{2} -1$

$q(-9)=7(81)-1$

$q(-9)=566$

Now we know that q(-9) is equal to 566.
