Solve the following system by the substitution method. 4x−14=−y
3x−y=0

(,)

4x−14=−y equation 1

3x−y=0 equation 2

Multiply equ 1 with -1

14-4x=y

Subsitute equ 1 in 2

3x-(14-4x)=0

3x-14+4x =0

7x-14=0

7x=14

X=2

3x-y=0

3(2)-y=0

6-y=0

Y=6

(2,6)

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.
