At royston's favorite clothing store, the cost of a pair of jeans is $4 more than twice the cost of a shirt. the cost of a pair of dress pants is $2 less than 2.5 times the cost of a shirt. if the cost of a shirt is s dollars and royston purchased 1 pair of jeans and 1 pair of dress pants, which expression represents the total amount he spent in terms of s? 5s − 2 4.5s − 2 (2s + 4)(2.5s − 2) 4.5s + 2

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
