Answer:
1°F to 7°F is the best range to store ice cream.
Step-by-step explanation:
The ideal storage temperature of ice cream = 4°F
The allowance in the temperature is 3°F
So, the range of the store = 4°F ± 3°F
Now, 4°F + 3°F = 7°F
and 4°F - 3°F = 1°F
Hence, 1°F to 7°F is the best range to store ice cream.
Hi!
For this equation, you can solve it by using the quadratic formula:
x=-b<span>±sqrt/b^2-4ab
-----------------------
2a</span>
Multiply all of the numbers together: 5 x 2 x 8 = 10 x 8 = 80 ways
−10x + 1 + 7x = 37
combine like terms
-3x +1 = 37
subtract 1 from each side
-3x = 36
divide by -3 on each side
x = -12
I believe that the correct answer is "a vertical line will have an equation that starts with y = #".
