Your friend says that the solutions to the inequality 5x - 14x < - 18 are x ≤2. Solve the inequality correctly. What error di
d your friend
make?
1 answer:
<h3>
Answer: x > 2</h3>
Work Shown:
5x - 14x < - 18
-9x < - 18
x > -18/(-9)
x > 2
The inequality sign flips when dividing both sides by a negative number.
Here's another approach you could take.
5x - 14x < - 18
-9x < -18
0 < -18+9x
18 < 9x
9x > 18
x > 18/9
x > 2
It's a slightly longer pathway, but it avoids a sign flip when you divide both sides by the positive number 9.
The sign flip happens two steps earlier when going from 18 < 9x to 9x > 18. In other words, A < B is the same as B > A.

Answer:
640
Step-by-step explanation:
In order of operations, do exponents before multiplying.
8 squared= 64
64 x 10=640
Answer:
5/9
Step-by-step explanation:
From the information, 8 are more than 6 feet tall and 7 have good aim.
Therefore, the probability that the coach would randomly pick a player over 6 feet tall or a player with a good aim will be:
= 8/27 + 7/27
= 15/27
= 5/9
The volume for 1 a. is 79.50700. (You just multiply 4.3 by itself three times)
I don't know what the second one is though, sorry.
Tangent (X) = Opposite Leg / Adjacent Leg.
Tangent (H) = 9/40
The answer is Tangent.
