Answer:
x is greater than or equal to -4
Step-by-step explanation:
I am not sure if I have to graph as well so I will just solve the inequality.
3x-12 greater than or equal to 7x+4
+12 +12
3x is greater than or equal to 7x+16
-7x -7x
-4x is greater than or equal to 16
-4x/-4 16/-4
x is greater than or equal to -4
Answer:
Jordan's purchase was $20
Step-by-step explanation:
3x5=15 5x1=5 5+15=20
Begin by multiplying both sides by 2 to get rid of the fraction. The standard form for a line is Ax + By = C, no fractions allowed. By multiplying we get 2y=-1x+3. Now move the -1x over by adding and we have the standard form we are looking for: x + 2y = 3.
Answer:
Step-by-step explanation:
–10.5 < 3a ⇒ -3.5 < a ⇒ a > -3.5
- <u>no</u> as variable has positive coefficient
b/6 ≤ 7 ⇒ b ≤ 42
- <u>no</u> as variable has positive coefficient
–4.5c > 9 ⇒ c < - 2
- <u>yes </u>as variable has negative coefficient
–21/5 ≤ –5/2d ⇒ (-21/5)*(-2/5) ≥ d ⇒ d ≤ 42/25
- <u>yes</u> as variable has negative coefficient
