Answer:

Luke is wrong because 4r + 5 + 2r = 6r+5.

You can only add numbers with the same variable, 4r and 2r have the same variable so they can be added while 5 does not have a variable, this means it cannot be added to 4r and 2r.

Step-by-step explanation:

4r + 5 + 2r

4<u>r</u> + 2<u>r</u> + 5

6r + 5

Solve the following equation. –4y + 8 = 4(2y – 2) – 2(–16 + 8y) A. y = –4 B. y = 4 C. y = –2 D. y = –6 I need Help I am utterly
leonid [27]
The answer is B. (y = 4)


Further explanation:

–4y + 8 = 4(2y – 2) – 2(–16 + 8y)
= -4y + 8 = 4 * (2y -2) - 2 * (-16 + 8y)
= -4y + 8 = ( 4 * 2y - 4 *2 ) - (2 * -16 - 2 * 8y )
= -4y + 8 = 8y - 8 - ( -32 - 16y)
= -4y + 8 = 8y - 8 + 32 + 16y
Move y’s to the left & numbers to the right
= -4y - 8y - 16y = -8 + 32 - 8
= 12y - 16y = -16 + 32
Y = 16 / 28
Y = 4 = (B choice)

Wayne is solving a system of linear equations.
Ulleksa [173]

Answer:

(-2, 6.5)

Step-by-step explanation:

Wayne can follow the line from (-2, 0) up to where it crosses the graphed line. The crossing point is approximately halfway between 6 and 7 on the graph, so can be considered to be 6.5.

If we put x=-2 into the equation and evaluate, we get ...

... y = (-3/4)(-2) +5 = 6/4 +5 = (1 1/2) +5 = 6 1/2

Thus the solution is (-2, 6 1/2).
