Solve the equations below. With explanations please.
Sophie [7]

Answer:

Step-by-step explanation:

y=-2x-4

y=5x+5

------------

-2x-4=5x+5

-2x-5x-4=5

-7x-4=5

-7x=5+4

-7x=9

x=9/-7

x=-9/7

y=5(-9/7)+5

y=-45/7+35/7

y=-10/7

Answer: x=-9/7, y=-10/7. (-9/7, -10/7).

----------------------------------------------------

-3x+y=8

2y=6x-10

----------------

6x-2y=10

-3x+y=8

-------------

y=8-(-3x)=8+3x

6x-2(8+3x)=10

6x-16-6x=10

-16=10

no solution

Answer: No Solution

--------------------------------

2y=4(x+3)

y-2x=6

--------------

y=4x+12

y=2x+6

--------------

4x+12=2x+6

4x-2x+12=6

2x+12=6

2x=6-12

2x=-6

x=-6/2

x=-3

y=2(-3)+6=-6+6=0

Answer: x=-3, y=0. (-3, 0).

-------------------------------------

x+2y=4

4x-2y=16

---------------

5x=20

x=20/5

x=4

4+2y=4

2y=4-4

2y=0

y=0/2

y=0

Answer: x=4, y=0. (4, 0).

Need help on this problem
soldier1979 [14.2K]

Hey there!

Let's look at our graph here. It is a 4 x 8 chart, which means there are 32 total squares. 12 of these squares are highlighted in black. This gives us 12/32, which is equal to 3/8. Therefore, we can eliminate answer D as an option.

Now, we are looking for a percent of a fraction. Usually when you draw a chart that represents multiplying fractions, the bars will overlap. We do see 5 gray squares, but if that is all, this chart would not really represent anything. Let's say it goes all the way across the top, giving us 8 gray squares, 3 of them also being black.

This means we have 8/32, or 1/4 as our other fraction. As we said before, 3 of these squares are both black and gray. This is 3/32, so the answer to our problem has to be 1/12.

We have fractions 3/8 and 1/4.

\frac{3}{8}(\frac{1}{4})=\frac{3}{32}= \frac{1}{12}

Therefore, our answer is H.

I hope this helps!
