Answer:
x ≥ −5 and x < 4
Step-by-step explanation:
-4x + 1 ≤ 21 and 5x + 2 < 22
5x + 2 < 22 =<u> x < 4</u>
We can plug it in: 5 x 3 + 2 < 22 = <u>17 < 22</u>
-4x + 1 ≤ 21 = x= -5 and lower
Plug it in: -4 x -5 + 1 ≤ 21 = 21 ≤ 21 = <u>x ≥−5</u>
So both answers would be:
x ≥−5 for -4x + 1 ≥ 21
x < 4 for 5x + 2 < 22
Probability of any event = ( favourable outcomes ) /total number of outcomes
Probability of = 3/10 + 2/9 = 
The answer is b. Great job! here ill show you the work.
15x +90 > 270
move constant to the right side and change its sign, like this:
15x>270-90
then subtract the numbers
15x>180
lastly, divide both sides by 15.
hope this helped!
