The mistake which Marcie made in solving the equation was when she added 2 to 6x and 2 to 22 to make ≤ 24. x ≤ −3.
Adding 2 to 6x would make 6x + 2, therefore this is the mistake that Marcie made solving the inequality.
All steps that Marcie did are right, but she forgot to change sign in last step.
Consider the inequality
Then
Group the numbers:
Separate terms with x and without x in different sides:
The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:
Answer: Marcie forgot to change sign in last step.
do it step by step will it work yes
Answer:
slope : -1, y-intercept : 13
Step-by-step explanation:
-x = -1 times x
+13 = 13 = y-intercept
