The solution is x = 4 and y = -1

Step-by-step explanation:

The system of equation is:

  • y = \frac{1}{2} x - 3
  • y = x - 5

To solve it using the elimination method do that

∵ y = \frac{1}{2} x - 3 ⇒ (1)

∵ y = x - 5 ⇒ (2)

- Subtract equation (1) from equation (2) to eliminate y

∵ y - y = (x - \frac{1}{2} x) - 5 - (-3)

- Remember (-)(-) = (+)

∴ 0 = \frac{1}{2} x - 5 + 3

∴ 0 = \frac{1}{2} x - 2

- Add 2 to both sides

∴ 2 = \frac{1}{2} x

- Multiply both sides by 2

∴ 4 = x

∴ x = 4

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 4 - 5

∴ y = -1

The solution is x = 4 and y = -1

Felicia is solving the expression -5(3x+2)+10x. Gregory is solving the expression -12-4x+?+?x. Both students simplified their an
densk [106]

Answer:

see the explanation

Step-by-step explanation:

we have

<em>Felicia</em>

-5(3x+2)+10x

Apply distributive property

-5(3x)-5(2)+10x

-15x-10+10x

Combine like terms

-5x-10

Let

a ----> the missing term with coefficient x in Gregory's expression

b ----> the missing constant  term in Gregory's expression

so

-12-4x+ax+b

equate Gregory's expression to Felicia's expression

-12-4x+ax+b=-5x-10

so

-12+b=-10 ----->b=2

-4x+ax=-5x ------> a=-1

so

Gregory's expression is

-12-4x+2-x

therefore

The missing terms are 2 and -x

The answer is 6 x 3 x 3 = 54.
I found this by finding the surface area with 9 x 6 and then seeing that 6 x 3 x 3 gives the same answer knew that one was correct, but I'm sure there's an easier way, good luck.
