Can someone help me??

Answers

Answer:

(8,8)

Step-by-step explanation:

The first equation says y and x are the same, so any x in the second equation can be replaced with a y, so

y = 2x - 8 and y = x, substituting x for y gives

x = 2x -8, subtract x from each side, add 8 to each side, get

8 = x

substitute that value back into the first equation

y = x, x= 8, so y=8

b.) 6m, 9m, 16m
c.) 16m, 24m, 38m
d.) 22m, 28m, 51m

Answers

Answer:

the largest angle=<PQR

c.) 16m, 24m, 38m

The largest angle of the triangle is ∠PQR and the measurements of the triangles are 16m, 24m, 38m

What is a Triangle?

A triangle is a three-sided flat figure or polygon with three angles.

A triangle has three vertices, and the internal angles amount to 180°.

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x L x B

For a right angle triangle

From the Pythagoras Theorem ,

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔPQR

Now , the measure of side PQ = 7

The measure of side QR = 8

The measure of side PR = 14

Now , for a triangle , the angle opposite the smallest side of a triangle has the smallest measure.

And , the angle opposite the largest side has the largest measure

So , the angle opposite to the side PR = ∠PQR

Therefore , The triangle's largest angle is ∠PQR

Now , the measure of the sides of the triangles are given and

a + b > c

when a = 16 , b = 24 and c = 38

16 + 24 > 38

40 > 38

Therefore , the measures 16m, 24m, 38m form a triangle

Hence , the triangles are solved

Which variable should an expression be substitute for?

Answers

9514 1404 393

Answer:

  x

Step-by-step explanation:

There is already an expression given for x, so that is the easiest variable to substitute for.

Substituting for x using the second equation, you have ...

  -3(-2y+14) +y = -14

  6y -42 +y = -14

  7y = 28

  y = 4

  x = -2(4) +14 = 6

The solution is (x, y) = (6, 4).

_____

Substitution for x is the easiest.

__

The first equation could be rearranged to give an expression for y:

  y = 3x -14

Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.
