Tell whether the equation represents a linear function.

5y = 20 − x
a. The equation is a linear equation.
b. The equation is not a linear equation.

A. The equation is a linear equation

Step-by-step explanation: It can be arranged in the form of y = mx + c, which means that this is a linear equation.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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.
