Answer:

D. (-7, -9)

Step-by-step explanation:

<u>Equation 1</u> : -5x + 5y = -10

<u>Equation 2</u> : -3x + 2y = 3

<u>Multiply Equation 1 by 2 and Equation 2 by 5.</u>

  • -10x + 10y = -20 [Equation 3]
  • -15x + 10y = 15 [Equation 4]

<u>Subtract Equation 4 from Equation 3.</u>

  • -10x + 10y + 15x - 10y = -20 - 15
  • 5x = -35
  • x = -7

  • -3(-7) + 2y = 3
  • 2y = -18
  • y = -9

<u>Solution</u>

  • (-7, -9)

If you were to roll the dice one time what is the probability it will NOT land on a 2? Put your answer in fraction form.
OLEGan [10]

Answer:

5/6

Step-by-step explanation:

On a standard 6-sided die, there is only one 2. That means that there are 5 other numbers that it could land on (1, 3, 4, 5, 6).

Using that information, the probability of it not landing on a 2 is 5 out of 6 or 5/6. This is because you must do part over whole. The "part" in this situation is the 5 "wanted" numbers, and the "whole" is 6 because there are six potential numbers that it could land on.

I hope this helps.

Quadrilateral ABCD has vertices A(1,0) B(5,0) C (7,2) D(3,2). Use slope to prove that ABCD is a parallelogram.
Galina-37 [17]

Answer:

AD \parallel BC

AB \parallel CD

Step-by-step explanation:

The vertices of quadrilateral ABCD are A(1,0) B(5,0) C (7,2) D(3,2).

The slope of side AB is

M_{AB}=\frac{0-0}{5-1} =\frac{0}{4}=0

The slope of side BC is

M_{BC}=\frac{2-0}{7-5} =\frac{2}{2}=1

The slope of side CD is

M_{CD}=\frac{2-2}{3-7} =\frac{0}{-4}=0

The slope of AD is

M_{AD}=\frac{2-0}{3-1} =\frac{2}{2}=1

AD \parallel BC

AB \parallel CD

We see that the opposite sides of the quadrilateral ABCD are equal.

Hence the quadrilateral is a parallelogram
