Answer:
if;
d=0 p=6
d=3 p=4
d=6 p=2
Step-by-step explanation:
just substitute the value into d and use algebra rules to solve!
The solution for the first inequality is a ≥ 2 or a ∈ [2, ∞), and for the second inequality the solutions are b < -5 or b ∈ (-∞, -5)
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have two inequalities:
a.) -12a +7 ≤31
b.) -9 > 3b +6
a) -12a +7 ≤ 31
-12a ≤ 31 - 7
-12a ≤ 24
-a ≤ 2
a ≥ 2 (sign changed because multiplied by a negative number)
a ∈ [2, ∞)
b.) -9 > 3b +6
-15 > 3b
-5 > b
or
b < -5
b ∈ (-∞, -5)
Thus, the solution for the first inequality is a ≥ 2 or a ∈ [2, ∞), and for the second inequality the solutions are b < -5 or b ∈ (-∞, -5)

Answer: x = 4.5
Step-by-step explanation:
4x + 14 = 32
Subtract 14 from each side
4x = 18
Divide by 4 on each side
x = 4.5
Answer:
1/6
Step-by-step explanation:
If this is a normal 6 sided she, there is only one multiple of 4 possible.
So, the probability is 1/6
