Consider the following pair of equations: y = −2x + 8 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

{y = -2x + 8, y = x - 1} = (3, 2) OR x:3 and y:2

Step-by-step explanation:

1. We are given the value of y in terms of x (an equation where the variable y is isolated).

2. Since y = x - 1, plug this into the first equation for y to start solving. (this is the value of y in terms of x)

3. x - 1 = - 2x + 8

4. Substitute "x" in for "y" in either equation but since the second is easier we will do that one.

Hope this helps! If you have any questions regarding concepts, please reach out!

d. is the correct answer

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
