Question

1. True or False: The y -intercept of the linear equation x – y = 4 is (0, 4).
False?...I think its -4

2. If 10 a > 17, then 30 a + 2 > ____ ?
53?

3. Which of the points below will satisfy the given system of inequalities? 2y>-2 and 15x<0
(-4, -1)

Answer 1

#1 and 2 are ok

#3:
is -8 > -2? No

2y > -2
y > -1
Hope one of the points provides that.

Answer 2

Oops. Got my x,y confused.
Anyway, y > -1, so (-4,-1) will not work.

Answer 3

the choices are: (-4, -1), (4, 1), (3, 0), (-3, -3), and (4, -1)
...

Answer 4

Yeah I thought you had your x and y confused...But I still don't see any of the solutions working..

Answer 5

so, pick the one with y < -1 and x < 0 !

Answer 6

(-3, -3)

Answer 7

Dang! got my < and > mixed up now. I don't see any good choices either. Is there a typo? y >= -1?

Answer 8

Yeah, none of the choices seem to be working. Now I'm just confusing myself.

The question is 2y> -2, 15x<0

Answer 9

If the problem is as stated, then none of the points work. Better check with your instructor. Even texts and online lessons/tests can contain errors.

Answer 10

Yes, I'm sure that is the problem. I will try to get it cleared out. Thanks for the help!
