How do you know before graphing, that a system of equations will have exactly one solution?​

Because an equation is a simulation of a variety of numbers and due to the inevitability that all mathematical questions are designed to only have one answer,You can only get one solution

Step-by-step explanation:

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.

y=x+9
