Create a polynomial with zeros: x = {-2,3}<br> I have no idea how to do this
aliya0001 [1]

Standard form of polynomial = ax² + bx + c

Zeros: x = {-2,3}

This gives the factors as, (x + 2) (x - 3)

On expanding this:

(x + 2) (x - 3)

x(x - 3) + 2(x - 3)

x² - 3x + 2x - 3

x² - x - 3

Polynomial = <em>x² - x - 3</em>

Trina is purchasing a new bike the store is having 20% off sale and she as 10% coupon of the sale price if the original price of
marusya05 [52]
20% of 89.75 is 17.95
\frac{20}{100}  =  \frac{x}{89.75}  \\ x =  \frac{89.75 \times 20}{100} =  \frac{1795}{100}  = 17.95
so :
89.75 - 19.95 = 71.8
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
\frac{10}{100}  =  \frac{x}{71.8}  \\ x =  \frac{71.8 \times 10}{100}  =  \frac{718}{100}  = 7.18
so the final answer is:
71.8 - 7.18 = 64.62
she has to pay $64.62
hope this helps

Answer:

The answer is y=-1x+8 or you can write it this way y=-x+8 either way will work fine.

y=mx+b

m=-1

y-y=m(x-x¹)

y-1=-1(x-7)

y-1=-1x+7

+1 +1
