What is the value of x in the equation 3x-4y=65, when y=4? x=134
O x=21 / 3
O x=23
X=27

Step-by-step explanation:

Given, value of y = 4

To find : Value of x

plug the value of y

Multiply the numbers : 4 and 4

Move 16 to right hand side and change it's sign

Add the numbers : 65 and 16

Divide both sides by 3

Calculate

Hope I helped!

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.
