Solve the system.... 2y+8x+58 and y-5x=11

Answers

Answer:

x=2, y=21

Step-by-step explanation:

there are two methods: substiution and elimation. I will be doing subtistution in this soultion:

first isolate y in either equation, it would be easier to do it in the second one.

y= 11+5x

Then, subtitute that into the first equation

2(11+5x)+8x=58 (it says 2y+8x+58 but I assume you mean 2y+8x=58?)

22+10x+8x=58

18x = 36

x=2

substitute that back into y = 11+5x, to get y=11+10 = 21

The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.

Answers

kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)

Answer:

Kyle's age = 18 years

Step-by-step explanation:

Let Megan's age = x

Kyle's age = 2x

Combined ages  of Megan and Kyle = 27

x + 2x = 27

   3x = 27           {Divide both sides by 3}

3x/3 = 27/3

x = 9

Megan's age = 9 years

Kyle's age = 2 * 9 = 18 years

  B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)

Step-by-step explanation:

Part A:

Angle WZY is the supplement of the given angle ZWX, so is ...

  ∠WZY = 180° -120° = 60°

Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...

  ∠W'Z'Y' = 60°

Part B:

The transformation right 2 and up 3 can be described by ...

  (x, y) ⇒ (x +2, y +3)

Then the translated vertices are ...

  W(-5, 3) ⇒ W'(-3, 6)

MN = TS

5x -2 = 3x + 1

Add 2 to both sides:

5x = 3x + 3

Subtract 3x from both sides:

2x = 3

Divide both sides by 2

X = 3/2

Now you have x solve for TS

TS = 3x + 1 = 3(3/2) + 1 = 4 1/2 + 1 = 5 and 1/2
