Which ordered pair is the solution to the system of linear equations y =-7x+2 and y = 9x-14?
shepuryov [24]

Answer:

(1, -5)

Step-by-step explanation:

Solve the system by setting the equations equal to each other, and solving for x:

-7x + 2 = 9x - 14

2 = 16x - 14

16 = 16x

1 = x

So, the x coordinate of the solution will be 1.

Plug in 1 as x into one of the equations, and solve for y

y = -7x + 2

y = -7(1) + 2

y = -7 + 2

y = -5

So, the y coordinate is -5.

The ordered pair solution is (1, -5)

A rectangular prism is 3 meters long, 4 meters wide, and has a total surface area of 94 square meters. What is its height?
inysia [295]
SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7

If a single 20 sided dice is tossed once what is the probability of rolling a 15 or 17
Alex17521 [72]
For a single 20 sided dice, a chance to get a certain number would be 1/20. For 2 numbers it will be a 2/20 chance, which can be simplified to a 1/10 chance that you will roll a 15 or a 17.

10x = 12x - 6

Subtract 12x from each side

-2x = -6
