Evaluate the expression 2(x – 3) + 3y when x = 5 and y = 3.

13

Step-by-step explanation:

2(x – 3) + 3y

Let x=5 and y = 3

2(5 – 3) + 3*3

Parentheses first

2(2) +3*3

Multiply

4+9

Add

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.
