Simplify 3x - 5 + 12x - 4x + 14 to 11x + 9
11x + 9 = 86
Subtract 9 from both sides
11x = 86 - 9
Simplify 86 - 9 to 77
11x = 77
Divide both sides by 11
x = 77/11
Simplify 77/11 to 7
<u>x = 7</u>
Pilar started with 80 and adds 10 each week.
y= 10x + 80 (ten seashells • weeks + 80 she started with)
Marisol started with 0 and adds 20 each week.
y = 20x (no need to add + 0 because she started with nothing)
Inequality:
y = 10x + 80 < y = 20x
Weeks:
I would reccomend just plugging in numbers (for example if I put in 5 I would determine if it was too high or low then go to the next number.)
I plugged it into an online graph so I can’t show my work but the answer is 8 weeks.
Answer:
the answer is C.
Step-by-step explanation:
Answer:
The axis of symetary would be -1.
It would be 3/5 because if you simplify it you would bet 3/5
