Question

Help Please!!! :(

Answer 1

with wat?

Answer 2

Which ordered pairs in the form (x, y) are solutions to the equation 3x – 4y = 21?

Choose all answers that are correct.

A.
(−3, 3)

B.
(−1, −6)

C.
(7, 0)

D.
(11, 3)

Answer 3

Which of the ordered pairs in the form (x, y) is a solution of this equation?




A.
Both are solutions.

B.
The first is not a solution, but the second is.

C.
Neither is a solution.

D.
The first is a solution, but the second is not.

Answer 4

1=C

Answer 5

2=A

Answer 6

3=(9,-3)

Answer 7

-9,3*

Answer 8

3x – 4y = 21
Try each answer choice:
A) (−3, 3): 3(-3) - 4(3) = -9 - 12 = -21 False.
B) (-1,-6): 3(-1) - 4(-6) = -3 + 24 = 21 True
C) (7,0): 3(7) - 4(0) = 21 True
D) (11,3): 3(11) - 4(3) = 33 - 12 = 21 True
A C, D are true.

Answer 9

which one is that, the first one? @aum

Answer 10

Sorry B, C and D are true.

Answer 11

for the first one?

Answer 12

Yeah, answer to the first one.

Answer 13

kk, what about the second, thats the one i'm have the most trouble with and thank you btw

Answer 14

6x - y/2 = 14
(-9,3). Put x = -9, y = 3:
6(-9) - (3)/2 = -54 - 1.5 = -55.5 False.
(2, -4). Put x = 2, y = -4:
6(2) - (-4)/2 = 12 + 2 = 14. True.

In these problems all you have to do is substitute the values of x and y and see if the given equation is true or false.

Answer 15

so its D? for the second one

Answer 16

For the second one all the link provides is an equation and two choices. And I showed above which choice is true.

Answer 17

thank you :)

Answer 18

The first is not a solution but the second one is.

Answer 19

thank you so much :)
