Answer:

B


Step-by-step explanation:

The first parenthesis is (y + 12) and the second parenthesis is ( - y - 12 ).


<u>These two has to be equal in order for her to combine terms and simplify further.</u>


<em><u>For them to be equal, she </u></em><em><u>SHOULD HAVE</u></em><em><u> factored out a  -7 from the second group of factors so the term inside the 2nd parenthesis would have been ( - y - 12 ) thus making the factoring and simplification possible!</u></em>

From the answer choices, B is right.

Here are the step for solving this:
1. 3y + 5 > 23
-5 -5
3y/3 > 18/3
y > 6

In words what you are doing is getting y by itself on one side. Subtract the 5 to undo the adding of 5 first. Then, divide both sides by 3.

Two supplementary angles differ by 34. find the angles..​
antiseptic1488 [7]

Answer:

107°

73°

Step-by-step explanation:

Let the two supplementary angles be x° and y°.

x + y = 180....(1)

Since, supplementary angles differ by 34.

Therefore,

x - y = 34....(2)

Adding equations (1) & (2)

x + y = 180

x - y = 34

_________

2x = 214

x = 214/2

x = 107°

Plug x = 107 in equation (1)

107 + y = 180

y = 180- 107

y = 73°

laila [671]

Answer:

See image

Step-by-step explanation:

To graph the inequality

-2x + y >= -10

Change it to y = mx + b form, use a solid line (bc of the "or equal to" underline)

y >= 2x - 10 We have y-intercept at -10 and slope 2/1, shading goes above the line.

The other graph is an absolute value graph; it has a v-shape. The 7 makes it stretched 7 times taller (and skinnier) the -4 by the x shifts the whole graph to the right 4 units. The -4 at the end of the equation shifts the whole graph down 4 units. See image. The shading goes above the V (kind of looks like inside)

The solution to the system is where the shading of the two overlap. It is mostly the shading for the absolute value graph except for a tiny triangle at the bottom. See image.
