If 2x+y=8 and x-1=y then what is y? Please be detailed I want to know more then just the answer but how to solve

This is Bridge Algebra 2 stuff. Well you see that 2x+y=8 and x-1=y. To slove for y you have to slove for x first to find y. So 2x+x-1=8 ( the reason I did that is because there is a y in that equation and I placed it on that equation) now lets slove this equation for x. So 3x-1=8( I add 2x with x) 3x=9 ( I made -1 a positive one and add it to 8) x=3 ( I divided 9/3 to get 3). Now that you have slove x we will use x to slove for y. So 3-1=y, 2=y. Your answer is y=2.

Answer:

B. 4

Step-by-step explanation:

If Triangle ABC is congruent to Triangle EFG, then A = E, B = F, and G = C.

In this case, we want to find FG. BC is congruent to FG. Therefore, FG is 4 inches.

7w + 6 + 2w = (w + 2)

Sindrei [870]

Hey there!

The correct answer is $w = \frac{-1}{2}$

$7w + 6 + 2w = w + 2$ ~ Write the equation

$9w + 6 = w + 2$ ~ Simplify

$8w + 6 = 2$ ~ Subtract $w$ from both sides

$8w = -4$ ~ Subtract $6$ from both sides

$w = \frac{-1}{2}$ ~ Divide both sides by 8

Hope it helps and have a great day!

The point (-7,4) is reflected over the line x=-3. Then the resulting point is reflected over the line y=x. Where is the point lo

Ne4ueva [31]

Answer:

(4, 1)

Step-by-step explanation:

Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':

(-3, 4) = (A +A')/2

2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)

The reflection over the line y=x simply interchanges the two coordinate values:

A'' = (4, 1)
