Answer:

13x+y=135

2x+2y=30

because when you substitute x (10) and y(5) you come out with the answer given to the equation

Hi :)

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

Let's insert 10 for x and 5 for y and see where we end up with a true statement

y=-5+x

13x+y=135

5=-5+10

13(10)+5=135

5=5

130+5=135

5=5

135=135

So here we have two true statements

So (10,5) is definitely a solution to this system

Let's try the other options

2(10)+2(5)=30

20+10=30

30=30

4(10)+5(5)=71

40+25=71

65≠71

Remember, an ordered pair is only considered a solution if it makes both equations in the system true.

x=-37+3y

10=-37+3(5)

10=-37+15

10≠-22

We already know that (10,5) is not a solution to this system, since it made the first equation false

2x=14+y

2(10)=14+5

20≠19

We already know that (10,5) is not a solution to this system, since it made the first equation false

So the answer's A

I hope that helps

Help me classify the triangles by its sides and measuring its angles :)
Anni [7]

Answer:

1. isosceles

2. Right

Step-by-step explanation:

Here, we want to give the kind of triangle in each of the diagrams

1. From what we can see, we have two sides equal to each other using the given markings. More specifically, the base sides are equal and that makes the triangle an isosceles triangle

2. From what we can see here, we have an angle of 90 degrees on one of the sides of the triangle. In other words, we have a right angle on one of the sides.

This makes the triangle, a right triangle
