Answer:

x+4y=-35

-8x-4y=28

Step-by-step explanation:

The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!

Answer:

D. g = $\frac{b}{2}$ + h + 2

Step-by-step explanation:

2 ( g - h ) = b + 4

(Divide both sides by 2)

g - h = $\frac{b+4}{2}$

(Simplify fraction)

g - h = 2 + $\frac{b}{2}$

(Add "h" to both sides)

g = h + 2 + $\frac{b}{2}$

D. g = $\frac{b}{2}$ + h + 2

Answer:

Emanuel did a mistake in her first step.

Step-by-step explanation:

The given expression is

$\left(\dfrac{3}{5}\right)\left(\dfrac{4}{9}\right)\left(-\dfrac{1}{2}\right)$

Emanuel solve this problem but she did a mistake in her first step. She distributes negative sign with 1 and 2 both which is incorrect. We can write negative sign with either 1 or 2 but not both.

Correct steps are:

Step 1:

$\dfrac{(3)(4)(-1)}{(5)(9)(2)}$
