Find the solution to the system of equations.

8x – 4y = 16
8x + 4y = 16

x= ___
y= ___

PLS HELP

Answers

Answer 1

Answer:

x =2, y =0

Step-by-step explanation:

First we can add the equations to get rid of the y terms in each.

Adding them results in 16x = 32

Dividing by 16 gives us x=2

Substituting this back into equation 1 gives us 8(2) -4y =16

Simplifying,

16 - 4y =16

-4y = 0

y = 0

In Exercises 1 and 2, determine whether the triangles are similar. If they are,
write a similarity statement. Explain your reasoning.

Answers

Answer:

1) yes, all of their angles are equal.  (75°, 45°, and 60°)

2) No, their angles are not equal. (42°, 48°, 90°  vs  58°, 32°, 90°)

Step-by-step explanation:

1.

ΔWXY and ΔRST are similar because they have equal angles.

2.

ΔJKM and ΔKLM are not similar because the angles are not equal.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

1.

In ΔWXY,

∠X = 75

∠Y = 60

∠W = 180 - (75 + 60) = 180 - 135 = 45

In ΔRST,

∠S = 45

∠R = 60

∠T = 180 - (45 + 60) = 180 - 105 = 75

Now,

We can say that,

ΔWXY and ΔRST are similar because they have equal angles.

2.

In ΔJKM,

∠J = 42

∠M = 45

∠K = 180 - (42 + 45) = 180 - 87 = 93

In ΔKLM,

∠K = 58

∠M = 90

∠L = 180 - (58 + 90) = 180 - 148 = 132

ΔJKM and ΔKLM are not similar because the angles are not equal.

Thus,

ΔWXY and ΔRST are similar because they have equal angles.

ΔJKM and ΔKLM are not similar because the angles are not equal.
