ABCD is a parallelogram.
kow [346]

Opposite sides of a parallelogram are equal lengths, so ...

... AB = CD

... 6x +30 = 2y -10

and

... BC = AD

... 2x -5 = y -35

_____

The equations can be put in standard form to get

... 3x -y = -20

... 2x -y = -30

Subtracting the second from the first, we get

... x = 10

Solving for y, we have

... y = 2x+30 = 2·10 +30 = 50

The values of x and y are x=10, y=50.

_____

AB = 6x+30 = 90

BC = 2x-5 = 15

Which of the following is the correct factorization of the polynomial below?
Finger [1]

Step-by-step explanation:

(x+3)(x-5)

= x²-5x+3x-15 = x²-2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again, (x-3)(x+5)

= x²+2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again , (x+3)(x²-4x+5)

= x³-4x²+5x+3x²-12x+15

= x³-x²-7x+15

But the given polynomial x³-15

So it is not the correct factorization.

So , optionD is the correct answer

Help me please??????
Deffense [45]
If Jayden needs 900, and he already has 375, first you need to find out how much more money he needs. Do that first.

2. His job pays him 155 a week, so 155w. If he needs to make at least 900, that means that it would be ok if he earned equal to 900, or more. So the amount he earns is greater than or equal to 900.

3. Solve for w. This should give you your answer.

I hope this helps!

Plz help me agh! It’s linear stuff
kherson [118]

Answer:

(1/2)x - y = -2

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Equality Properties

<u>Alg I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Standard Form: Ax + By = C

Step-by-step explanation:

<u>Step 1: Define equation</u>

Slope-Intercept Form: 2 + (1/2)x = y

<u>Step 2: Find Standard Form</u>

  1. Rewrite:                                        y = (1/2)x + 2
  2. Subtract 1/2x on both sides:       y - 1/2x = 2
  3. Factor negative:                          -(1/2x - y) = 2
  4. Divide both sides by -1:               1/2x - y = -2
