Find the value of x and y

Mathematics
1 answer:
Ann [662]3 years ago
5 0

Answer:

x=16

y=23

Step-by-step explanation:

angle (4x+4) and angle (7x-44) are alternate exterior angles which are equal, so we can set up an equation like this to find x:

4x+4=7x−44

calculate it then you'll get x=16

for the next one I'm not really sure how to explain since they are not labeled but,.. since we have the measure 39 we can figure out by using the pairs 'interior angles on the same side of a transversal' and 'vertical angles' that it's equal to 141, so to find y we use the equation

8y-43=141

calculate it and you'll get y=23

Answer:

I would just say that Manuel seems to be moving at a pretty fast or decent pace at first, and he then at some point, doesn't move at all because the straight line shown in the middle of the graph shows us that there isn't any movement from him. (at least with what the information on the graph is giving us) At the very end of the graph, I can see that he eventually reached his destination, and at a very fast rate! (because the graph seems to obviously end at a point)

Step-by-step explanation:

I'm a Freshman in High School, and I haven't learned about graphs as simple as this one in a hot-minute! [a year or two maybe] Sooo...I hope I helped a little bit though.

But even if I am completely wrong, just know that whenever a straight vertical line like that is on a graph, it means that there was either NO motion detected or that there wasn't any data at that moment to be graphed. {BUT} In this case, Manual wasn't moving at all for that time being, because the graph has a STRAIGHT VERTICAL LINE in the middle of it.

I would also write down in my answer, that it looks like he was riding a bike, or was driving, or was maybe running, because it looks like either his destination was very close to where he originally started, OR he just got to his destination quickly via transportation.

— 3х – 2y = 16<br> х+ 9y = 28
Alla [95]

Answer:

x=-8

y=4

Step-by-step explanation:

first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16

3x+2y=-16

(x+9y=28)3 _multiply with 3

3x+2y=-16

3x+27y=84

use minus(-) =3x-3x=0

=2y-27y=-25y

=-16-84=-100

the result:-25y=-100

y=4

take any simple equation and replace y with 4

x+9y=28

x+9(4)=28

x+36=28

x=28-36

x=-8

answer:x=-8,y=4
