Question

What is the solution of the system? Use elimination.

3x – 4y = –24
x + y = –1

medal awarded

Answer 1

3x-4y=-24
x+y = -1

3x-4y=-24
- 3x +3y = -3
-------------
-7y = -21
7 = 3

Answer 2

I mean y = 3

Answer 3

See if you can solve from there :)

Answer 4

Just substitute y=3 back into the 2nd equation.

Answer 5

-4

Answer 6

yes :)

Answer 7

The local zoo is filling two water tanks for the elephant exhibit. One water tank contains 34 gal of water and is filled at a constant rate of 4 gal/h. The second water tank contains 30 gal of water and is filled at a constant rate of 2 gal/h. Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank. What are the constraints on the system? do u know this

Answer 8

I'm sorry, no. But You could post this up and see if anyone knows?

Answer 9

Which ordered pair is a solution of the inequality?

y>=4x - 5

Answer 10

\[y \ge4x-5\]?

Answer 11

What are the options?

Answer 12

can u solve it without or no because i wanted to see if any answers matched yours

Answer 13

You can't solve without for this question

Answer 14

A. (3, 4)
B. (2, 1)
C. (3, 0)
D. (1, 1)

Answer 15

i agree

Answer 16

You just plug in these values into the equation and see if it makes sense.

Answer 17

A

Answer 18

e.g
\[4 \ge 4(3)-5 ?\]

Answer 19

That isn't correct.

Answer 20

the third

\[0 \ge 3(3) -5?\]

Answer 21

I think it's D

Answer 22

the fourth

\[1 \ge 4(1)-5?\]

Answer 23

D is correct

Answer 24

a and c is wrong

Answer 25

Sorry,

the second is

1> 4(2) -4

Answer 26

-5*

Answer 27

which isn't correct. So, only D can be the answer.

Answer 28

Graph the inequality.

y < 3x - 5

Answer 29

Plug in values for y and x,
eg. when y = 0, x =?
and when x= 0, y =?

Then you have two points and can graph it.
Or, get more values and graph it too
