Answer:
Correct answer is B. (-2,4)
Step-by-step explanation:
Given: y = 2x^2 + 8x + 12
if x = 2,
Use substitution: y = 2(-2)^2 + 8(-2) + 12
y = 8 - 16 + 12
y = -8 + 12
y = 4
So, (-2, 4) would be your answer.
I hope this helps!!!
Answer:
0.15*t < 5.00
33 texts
Step-by-step explanation:
given : $0.15 per text; unlimited cost is $5.00
# of texts = t
0.15*t < 5.00
t < 33.33; since you cannot make 33.33 texts i will round down to 33 texts.
Basically you can send or receive up to 33 texts and it will be cheaper than $5.00
0.15(33) = $4.95
at 34 texts, 0.15(34) = $5.10
The Pythagorean theorem a²+b²=c²
16²+18²=c²
256+324 = 580
√580
24=4x-6
(add six both sides)
30=4x
(divide 4 both sides.)
7.5=x (roughly)
Answer:
Store 1 has the better deal.
Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.
3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35
As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
