Answer:
Step-by-step explanation:
hello :
y= x² + x + 1 ....(*)
and
y= -x - 2....(**)
(**)-(*) : 0 = (x²+x+1) -(-x-2)
x²+2x+3 = 0
(x²+2x+1)+2 = 0
(x+1)² = -2 ...... no solutions in R
To solve this problem you have to do 14.99 x 7 + 58 (starting fee)
the answer should come out to $162.93
Hope this helps :)
D and b maybe... (I’m not super sure though)
10 different pairs. Since there are 5 different brands you simply add 4+3+2+1 to get 10.

f =
= × =
Now we convert this proper fraction to mixed fraction.
=
