Answer:

(2,-2)

Step-by-step explanation:

The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.

-3x+4 = 4x-10

-3x-4x+4-4 = 4x-4x-10-4

-7x = -14

-7x/-7 = -14/-7

x = 2

Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.

y = 4(2)-10

y = 8-10

y = -2

Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)

Answer:

V_{cylinder}=3584\pi \thinspace yd^3

Step-by-step explanation:

Volume of a cylinder is just the area of the circle-surface multiplied by the height of the cylinder.

V_{cylinder}=\pi r^2 h

We're given that the radius=8 and height=56

V_{cylinder}=\pi r^2 h

V_{cylinder}=\pi (8)^2 (56)

V_{cylinder}=3584\pi \thinspace yd^3

I won a sweepstakes and will receive money every week for 52 weeks. The first week, I will receive $500 and every week after tha
krok68 [10]

Answer:

$3100

Step-by-step explanation:

You can determine this by multiplying 52 by 50, because you get 50 dollars for 52 weeks, then add 500 to it, because you get 500 dollars at first. 52 times 50 is equal to 2600, and 2600 + 500 is equal to 3100. You will receive $3100 over the course of 52 weeks.

Julie cashed a paycheck and repaired her brother $10 that she borrowed from him. She then spent $30 on fuel for her car and half
pochemuha
Remark
She starts out with x
She spends 10 dollars paying back her brother (that's - 10)
She spends 30 dollars on fuel (that - 30)
She spends 1/2 what's left on a tent ( that's 1/2 (x - 10 - 30) )
She then spent 29.45  on running shoes. 1/2 (x - 10 - 30) + 29.45 is her expenditures.

After all that she has 17.75 left. 

Equation
x - 10 - 30 - 1/2(x - 10 - 30) - 29.45 = 17.75   

Solve
Begin by adding 29.95 to both sides. 
x - 10 - 30 - 1/2(x - 10 - 30)  = 17.75 + 29.45 
x -10 - 30 - 1/2(x - 10 - 30)  = 47.20  Add the like terms on the left.
x - 40 - 1/2(x - 40) = 47.20 Add 40 to both sides. Don't go inside the brackets.
x - 1/2x + 1/2 (40) = 87.20
1/2 x + 20 = 87.20                        Subtract 20 from both sides.
1/2 x = 67.20                                Multiply by 2
x = 134.40

How to draw an ray ???
vovangra [49]
A ray starts at one point and goes on forever.

So you just draw a point and a line extending from it with an arrow at the end of the line(the arrow tells you that it goes on forever).
