Yes, both men could drive at the rate of 112 miles in 2 hours. This is because you need to find the unit rate. For Theo's unit rate it is 57 miles per hour while Lex could drive at 62 miles per hour. Finally, the last statement ask if they could drive at a unit rate of 56 miles per hour and yes both men can.
Answer:
<u>No, it's not a function.</u>
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. <u>Therefore, this is not a function.</u>
9x^2 + 6x = 1
Factor out 3x
3x (3x +2)=1
Use the zero product property
3x=1
3x+2 = 1
X= +1/3 and -1/3
