Answer:
y=-x-11
Step-by-step explanation:
2x + 4 > 8
Step 1: Subtract 4 from both sides.
2x + 4 − 4 > 8 − 4
2x > 4
Step 2: Divide both sides by 2.
2x/2 > 4/2
x > 2
2x − 3 < 5
Step 1: Add 3 to both sides.
2x − 3 + 3 < 5 + 3
2x < 8
Step 2: Divide both sides by 2.
2x/2 < 8/2
x < 4
Answer:
a = - 1.1
Step-by-step explanation:
Condition for a single variable function f(x) to be decreasing is f'(x) < 0.
So, in our case, .
Then, differentiating with respect to x on both sides we get,
⇒
⇒
{Dividing both sides with - 1 and hence the inequality sign changes}
⇒
⇒ 8 > - 6x³ {Multiplying both sides with x³}
⇒ 6x³ > - 8 {Interchanging the sides}
⇒
⇒ x > - 1.1
Therefore, a = - 1.1. (Answer)
I think it’s 155 because if you line them up greatest to least it’s the number in the middle
