Question

what is the solution for this inequality ? -4x <= 28

Answer 1

can you solve the equation -4x = 28 ?

Answer 2

i don't think it's an equation i was thinking b is the answer .
A. x > -7
B. x < 7
C. x < -7
D. x > 7

Answer 3

this <=
means less than or equal to

Answer 4

yes. it's not an equation.
but first, can you solve it if it's an equation?

Answer 5

i'm not sure ,but it makes sense

Answer 6

what is your answer for x if -4x = 28 ?

Answer 7

-7 ?

Answer 8

correct.
you can work inequality like you work an equation
so, if -4x = 28 you got x = -7
but for inequality -4x <= 28 didn't mean x <= -7
remember, in negative number, -3 < -2 (though 3 > 2)
so, if you found -x <= a, that means x >= -a
so, can you find the answer of your question now?

Answer 9

are you still confused or you've got your answer?

Answer 10

is it c ?

Answer 11

no, it's not
for inequality -x <= a, it's the same as x >= -a
if -4x <= 28, it's the same as 4x >= -28
so the answer is ?

Answer 12

A ? !

Answer 13

yes.
the answer for -4x <= 28 should be x >= -7 though
but if there's no option for that, A is the best option.
