Find the solution of the system of equations.
10x – 2y = 18
-10x + 9y = -46

x=1, y=-4. (1, -4).

Step-by-step explanation:

10x-2y=18

-10x+9y=-46

7y=-28

y=-28/7

y=-4

10x-2(-4)=18

10x+8=18

10x=18-8

10x=10

x=10/10

x=1

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
