If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.
Let
C-----------------
> charges for the purchases to the credit card
<span>r-------------------
> the interest rate </span>
X------------------
> total cost of the purchase
we know that
C=4120
r= 22.45%=0.2245
X=C*(1+r)
substituting the values in the formula
X=(4120)*(1+0.2245)=
(4120)*(1.2245)=5044.94
the answer is
$5044.94
Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
