1. Mike is buying a new video graphics card for his computer. If x represents the kost prior to an 8.5% sales tax, which expression represents the total cost of the
graphic card?
a. X+0.085x
b. X- 0.085x
c. X+0.085
d. X-0.085

38 points!! Will give crown

x + 0.085x

Step-by-step explanation:

Because.. in the last sentence it says the total cost which means add so then you eliminate b and d...so after that before 8.5% it says sales tax...so then that is when you add a x at the end. so it isx+0.085x.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
