- 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:
I believe (D)
Step-by-step explanation:
-5x + 7 = -13
-7 -7
-5x = -20
-5/-5 -20÷-5
x=4
Answer:
y = 4.4
x = 1/5
Step-by-step explanation:
5x -4 = -3
5x -4 +4 = -3 +4
5x = 1
x = 1/5
y = -3(1/5) + 5
y = 4.4
Use the slope formula (y2-y1) / (x2-x1):
(6-10)/(24-0) = -4/24 = -1/6
