Determine the value of x and y in the following systems of equations5x-2y=4 ; -2x+y=2.
V125BC [204]

Answer:(x,y)=(8,18)

Step-by-step explanation:

Given

5x-2y=4-------1

Second Equation

-2x+y=2-----2

Now multiply equation 2 by 2 and it to equation 1

5x-4x+0=8

x=8

substitute it in equation 1

5\times 8-2\times y=4

36=2y

y=18

Therefore

(x,y)=(8,18)

There are 5 red pens and 10 black pens in a cup. If a person randomly selects 3 of them, what is the probability that they're al
kolbaska11 [484]

Answer:

option a)

0.286

Step-by-step explanation:

Given that,

number of red pens in cup = 5

number of black pens in cup = 10

number of pen randomly selected = 3

There are 5 red pens and 10 black pens. So there are 5 + 10 = 15 pens in all.

probability of having all red pens = (5/15 x 4/14 x 3/13)

                                                       = 2/91

probability of having all black pens = (10/15 x 9/14 x 8/13)

                                                           = 24/91

probability that all pen are of same colour = 24/91 + 2/91

                                                                      =  2/7

                                                                      ≈ 0.286

Help me please i’ll give points !!
Keith_Richards [23]

Answer:

Slope of PV = -4

Step-by-step explanation:

Coordinates of the vertices of the given triangle PSV,

P → (2, 4)

S → (3, 4)

V → (3, 0)

Slope of the segment between two points (x_1,y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of segment PV will be,

Slope = \frac{4-0}{2-3}

          = -4

Slope of PV = -4
