F ( x ) = 4 x² + 8 x + 7
a = 4, b = 8
The axis formula is:
x = - b / 2 a
x = - 8 / (2*4) = - 8 / 8 = -1
Answer:
The axis of the graph of the function is x = - 1.
Answer:
Step-by-step explanation:
Step 1. Switch sides.
Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.
Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

Answer:
one
Step-by-step explanation:
16, because its 12 and you add one-third to 12 so that means its $16
Answer:
in order to convert Celsius to Fahrenheit, you will need to use this formula: F = 9/5C + 32. Therefore, you will need to solve for C or substitute values and solve in that manner. To find Fahrenheit temperature for -20 degrees Celsius, you can just plug it into the formula. Therefore, F = 9/5 (-20) + 32 and F = 28.4. If you were given 59 degrees Fahrenheit you would get: 59 = 9/5C + 32 and this would give you 27 (5/9) = C, after you have plugged the values into the above formula. When you simplify you, you get C = 15.
