Which of the following is the solution to the system of equations?

drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

$\frac{5}{4} = 2 - \frac{3}{4}$

y = 3x - 1

$\frac{5}{4} = 3 \times \frac{3}{4} - 1$

$\frac{5}{4} = \frac{9}{4} - \frac{4}{4}$

Hope this helps ^-^

If y varies directly with x and y = 5 when x = 4, find the value of y when x = -8

Ket [755]

Answer:

-10

Step-by-step explanation:

y : x

= 5 : 4

4z = -8

= -8 / 4 = -2 = z

y : x

= 5 * -2 : 4 * -2

Combine like terms to simplify the expression: 2a+3b-4c-b+2a+2c

Ulleksa [173]

Hey there! I'm happy to help!

First let's combine all of the terms with a.

2a+2a=4a

Now the ones with b.

3b-b=2b

And the ones with c.

-4c+2c=-2c

So, our simplified expression is 4a+2b-2c.

Have a wonderful day! :D
