Answer:
It's letter c
Step-by-step explanation:
you have to × the 0.5 and 1
#3: 81
I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.
3^4 = 3 × 3 × 3 × 3
3^4 = 9 × 3 × 3
3^4 = 27 × 3
3^4 = 81
x≥ -4/55, x≤−89
Step 1: Subtract 1 from both sides.
−110x+1−1≤9−1
−110x≤8
Step 2: Divide both sides by -110.
−110x/-110≤8/-110
x≥ -4/55
