Question

Which of the following points are solutions to the system of inequalities shown below?

Check all that apply.

y>5x - 2
y<5x + 3

A. (4, 23)
B. (4, 20)
C. (-5, 25)
D. (5, 28)
Are, A,B,C,D all right?
or should there be just 2. and if so which 2. kinda in a scramble and need the answer quickly.

Answer 1

draw that and get the intersection area

Answer 2

5x+3>y>5x-2.
solve it

Answer 3

Since the numbers are so big you technically dont even need to draw it.
You can plug in the values for each and if it's true, then that's a solutions.
I'll do the first ordered pair:
23>5(4)-2
23>20-2
23>18
^That's true because 23 is greater than 18.
Do the second equation to make sure..
23<5(4)+3
23<23
^That's not true because 23=23. So the first ordered pair (4,23) is not a solution.
Do that for the other 3, I hope that helps!

Answer 4

ok thanks!!

Answer 5

No prob :)

Answer 6

Ok I have a question so the next problem says this:
Which of the following points are solutions to the system of inequalities shown below?

Check all that apply.

y > 6x + 5
y < -6x + 7

A. (2, 17)
B. (8, 8)
C. (-2, 18)
D. (0, 6)
E. (-2, 19)
F. (2, 18)
F was the only one that works with both equations so would that be the right answer?
I have this question and 2 more q's on this test and i have to get em right...
@bruhhh

Answer 7

??

Answer 8

F doesn't work for me?
18>6(2)+5
18>17, so thats true. but for the second..
18<-6(2)+7
18<-5, which isn't true.

Answer 9

Sorry the page keeps crashing -.-

D is the only one that works for me :) Make sure you check your answers & remember a negative times a negative is positive.

Answer 10

No problem!! And thanks. :D
