What is the solution to the system of equations? x+y=6 x=y+4

Solve for x in x + y = 6

x = 6 - y

Substitute x = 6 - y into x = y + 4

6 - y = y + 4

Solve for y in 6 - y = y + 4

y = 1

Substitute y = 1 into x = 6 - y

x = 5

Therefore,

x = 5

y = 1

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

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.
