What’s the rate of change of the table above? A) -1/3 B) 1/2 C) -1/4 D) 1/5

insens350 [35]

answer is option D

because you can divide them like

$\frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5}$

so the option is D

Which of these equations have no solution? Check all that apply.

dlinn [17]

First one simplifies to 2x + 6 = 2x + 7 which can't be true so this one has No Solution.
Same applies to the second equation ( 5x + 15 = 5x - 15) No solution

also the last one has no solution because it simplifies to 4x + 20 = 4x + 19

3y - 21 = 12x Help please

Irina18 [472]

Simply
3Y+-21=12X

Re-order the terms
-21+3Y=12X

(Solving for Y variable)

Move all terms containing y to the left, all other terms to the right.

Add 21 to each side of the equation
-21+21+3Y=21+12X

Combine like terms: -21+21=0
0+3Y=21+12X
3Y=21+12X

Divide each side by 3
Y=7+4X

Simplifying
Y=7+4x
I hope this helps!! :)
