Answer:
Step-by-step explanation:
A function maps an x-value to a single y-value. The graph of the parabola on the left does that.
The table on the right maps -1 to both 10 and 20, so does not meet the definition of a function.
Answer:
y=-3
Step-by-step explanation:
16/2=8
-6/2=-3
- 2x + 3 > x + 24
First we must get all variables on the same side and constants on the opposite side. To do so we subtract x from the right and the left. Then subtract 3 from both sides as well.
- 2x - x > 24 - 3
Now we combine like terms:
- 3x > 21
We must isolate the variable x. In order to do so, we divide both sides by - 3. When you divide by a negative number, you must also flip the inequality so the greater than becomes a less than.
x < 21 / - 3
x < - 7 is your answer.
Answer:
-10 < x < -8
Step-by-step explanation:
Envision a number line. There is one whole number, -9, and and an infinite amount of fractions (rational numbers) and irrational numbers between -10 and -8.
X could be any of those values.
