Find the value of n that makes DEF-XYZ when
DE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1, and

Answers

Answer: n=3

Step-by-step explanation:

Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.

Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:

5/4(4n+4)=7n-1. Now distribute:

5n+5=7n-1. Now simplify:

6=2n. Now simplify again:

n=3

Hope this helps you with your big ideas math hw!

The value of is n=3

Important information:DEF-XYZ whenDE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1.

The calculation is as follows:

5/4(4n+4)=7n-1.

Now distribute:

5n+5=7n-1.

Now simplify:

6=2n.

n=3

What number would you multiply the 2nd equation by in order to eliminate the y terms?
4x - 4y = 16
2x + y = 5

Answers

Answer:

x=3

y=-1

Step-by-step explanation:

first multiply the 2nd row by 2 so you will get

4x-4y=16

4x+2y=10

then subtract the 2nd row from the first row and so you will get

-6y=6

then solve for y in the above equation

y=-1

then substitute y=-1 into any 2 equations .

i picked the first 1

4x-4 × -1=16

then solve for x .

you will get

x=3

Mabe b I’m not for sure

Answer:

A = Hard to do, B = Easiest, C = Pretty Easy, D = Hard

Step-by-step explanation:

Step 1:

5x - 2y = -18

x - 8y = 80

__________

Step 2:

4(5x - 2y) = (-18)4

20x - 8y = -72

__________

Step 3:

20x - 8y = -72

x - 8y = 80

__________

Step 4:

21x = ?

Also, this equation isnt a substitution question, the way to solve this is by using elimination, you can tell because the values are lined up perfectly, sub. is used when y/x, is on the bottom left or right, and the other is on the opposite.

The question of the pic was cut off at the top and it says -

Line W is graphed on the coordinates plane below.

Answers

Answer: A

Explanation:

Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.

Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.

Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.

Which statement identifies the central idea of the text? A-Restorative justice is less effective when it is used to address serious crimes because some crimes are unforgivable. B- When offenders are forgiven by victims through restorative justice, the victims can heal and the offenders can understand their actions and better themselves. C- Young people should have more opportunities for restorative justice, as they are less in control of their emotions and more likely to act impulsively or violently. D- While restorative justice can help the victims, it's important to use punishment and rehabilitation to ensure that offenders don't commit another crime.2. Part B. Which TWO details from the text best supports the answer to Part A. A- Anns face was covered in bandages, and she was intubated and unconscious, but Andy felt her say, forgive him. His response was immediate. No, he said out loud. B- Visitors to Leon County Jail sit in a row of chairs before a reinforced-glass partition, facing the inmates on the other side like the familiar setup seen in movies. Kate took the seat opposite Conor, and he immediately told her how sorry he was. C- The processes are designed to be flexible enough to handle violent crime like assault, but they are rarely used in those situations. And no one I spoke to had ever heard of restorative justice applied for anything as serious as murder. D- Conor says that he would frequently fall into this wrathful anger, and on this day there was so much anger, and I kept snapping. Ann started sobbing, saying that Conor didnt care and that she wanted to die. E- Because we could forgive, people can say her name. People can think about my daughter, and they dont have to think, Oh, the murdered girl. I think that when people cant forgive, theyre stuck. F- Still, their forgiveness affected Conor, too, and not only in the obvious way of reducing his sentence. With the Grosmaires forgiveness, he told me, I could accept the responsibility and not be condemned. what differences between the northeastern and southeastern United States do you think still exist today In your opinion did Dolly Madison actFoolishly or heroically in deciding to remainat the White House?
