-4x+5 + -13x+39=180 angle measure

Answers

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

Answers

Answer:

they are parallels

Step-by-step explanation:

they have the same slope but different y intercepts so they are parallel

Answer:

Parallel

Step-by-step explanation:

First, you should put the second equation in slope-intercept form, it would be y=3x+8.

If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

2x + 5y = -24
3x - 5y = 14
Solve by elimination
y and x

Answers

Answer:

x = -2

y = -4

Step-by-step explanation:

The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*

so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.

that would leave

5x = -10

divide both sides by 5

x = -2

Now that we know x = -2, we can plug in -2 into one of the equations to find y.

2 ( -2) + 5y = -24

-4 + 5y = -24

-4 + 4 + 5y = -24 + 4

5y = -20

y = -4

x = -2

y = -4

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

The lengths of the sides of the triangle are given as,

Let Base, b = 3.6 cm

Perpendicular, p = 4.8 cm

Hypotenuse, h = 6 cm

Now, use the equation of Pythagoras' theorem,

h² = p² + b²

6² = 4.8² + 3.6²

36 = 23.04 + 12.96

36 = 36

It satisfies Pythagoras' theorem, which means that it is a right triangle.

The two prisms below are similar. What is the value of x?
10
15
A. 1
B. 15
C. 10
D. 5

Answers

The correct option is D, the value of the missing side x is 5.

How to find the value of x?

If the two prism are similar, then there is a scale factor that when multiplied by the dimensions of the blue prism, we get the dimensions of the green one.

If that scale is k, then we can write:

3k = 15

Solving for k:

k = 15/3

k = 5

Now, the correspondent side to the one that measures x, has a measure of 1 unit (in the blue prism), then the value of x is:

1*k = x

1*5 = x

5 = x

The correct option is D.

All my college friends were going, and we decided to dress for the theme, complete with headbands, leg warmers, blue eyeshadow, and teased hair. The night of the party, everyone looked great and we all had a good time.Then I decided to show off. About ten minutes before the party ended, I started trying moves I learned long ago when I dreamed of being an Olympic figure skater. I actually had never been good enough on the ice to get anywhere near the Olympics, but I loved skating and was pretty decent at one point. There I was at the party, spinning, twirling, and skating backward. Then I decided to bring my friend Heidi in on the fun, so I grabbed her hands and pulled her along with me as I skated backward. I was smart enough to be looking behind me to make sure I wouldnt bump into anyone, but I was not smart enough to pay attention to my balance, which I lost.I fell down onto the newly buffed rink floor. Before I knew what was happening, Heidi tripped and fell on top of me, and I heard a crack. I remember feeling the wind get knocked out of me, and then a rush of faces looking down asking if I was okay. My friend Kathleen, who was studying to be a nurse, asked questions to make sure I wasnt seriously injured, and another friend called an ambulance. Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.In the hospital I learned that I had broken a rib and fractured my collarbone. Kathleen had come with and assured me that I was lucky: it could have been much worse. Looking back, I have to laugh at the reaction we got from the hospital staff. Every time a new doctor or nurse walked into my room, we felt the need to explain our getups. The explanation was generally met with blank stares from people who had much more pressing concerns than what the girl in Room 3 was wearing.I went home with strict instructions to move as little as possible for the next few weeks. Lucky for me, I was on summer break so I didnt have to worry about school. Id been planning to stay in my off-campus apartment and work that summer. Instead, I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life. The next day, Heidi called and apologized profusely for falling on me. I thanked her but pointed out that it had been my fault that I ended up getting hurt.Even so, we all feel terrible that you ended up in the hospital at the end of a great party, Heidi said. Listen, I called a bunch of people who were there and asked if they wanted to volunteer for a meal drop-off schedule. I have your breakfast, lunch, and dinner covered for the next three weeks. I needed a moment to process what Heidi was telling me. Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks. The thought of an all-fast food diet had made me a little nauseous, but I knew I wouldnt be able to cook. Now my friends were coming to my rescue.Starting the next morning, in addition to bringing amazing home-cooked meals, as well as some great take-out, my friends took turns visiting me so I didnt get lonely. Those weeks ended up flying by. Before I knew it I was up and about again.Eventually, my friends let me in on what a good laugh they had the night of the party once they knew I was going to be all right, of course. As soon as my rib and collarbone healed I had a pretty good laugh about it, too. I didnt mind that they had laughed. I decided that any group of friends willing to cook for me during summer break was allowed to laugh at me.Which excerpt from the story supports the inference that the narrator was not planning to ask for any help during her recovery?I thanked her but pointed out that it had been my fault that I ended up getting hurt.Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks.I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life.Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.
