Which value is NOT a solution of the inequality -2x + 5<7?
2 answers:
Answer:1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-2*x+5-(7)<0
Step by step solution :

One solution was found :
x > -1
Answer:
its 1, i think...
Step-by-step explanation:
If they are asking which one would equal to -2x+5<7 just combine like terms by moving the 5 to the 7 and get 7-5=2. So -2x=2, then 2/-2 is -1. Basically the answer is x=-1. But it seems like thats not a choice...

Answer:
n = 225
Step-by-step explanation:
Multiply 15 by 15
y = -2x + 6
Steps:
y = mx + b
m is slope
b is the y-intercept
m = -2
b = 6
plug in m and b
y = -2x + 6
Answer:
y>-3 y>-7
Step-by-step explanation:
