In the below system, solve for y in the first equation. x − 3y = −6 2x − 7y = 10

Step-by-step explanation:

The given system of equation is;

and

To solve for y in the first equation; we add to both sides.

We now divide through by -3;

This implies that;

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.
