Answer:
4 = 8. 7 = 14
Step-by-step explanation:
k = 2xd
8 = 2x4
14 = 2x7
We need to see Hazel's work for simplifying an inequality and see if she had a mistake or not.
The answers are:
a) Step 4.
B) She did not change the direction of the inequality symbol.
a) Let's analyze each step:
She starts with:
3*(t + 1) - 4*t ≥ −5
Step 1:
3t +3−4t ≥ −5
Here what she does is distributing the first product, she goes from:
3*(t + 1) to 3*t + 3
Step 2:
−t+3≥−5
Here what she did is adding "3*t - 4*t = (3 - 4)*t = -t"
Step 3:
−t ≥ −8
Here she subtracts 3 in both sides.
Step 4:
t ≥ 8
Here is the mistake.
B)
Here what she does is multiplying by -1 in both sides, her mistake is that we multiply both sides by a negative number in an inequality, the direction of the inequality must change, so here is her error.
So what she actually should had is:
-t ≥ -8
(-1)*(-t) ≤ (-1)*(-8)
t ≤ 8
