Same method as the last problem:
d: y-2
x: x-0 = x
y: y--2 = y+2
{y - 2}^{2}  =  {x}^{2}  +  {(y + 2)}^{2}  \\  {y}^{2}  - 4y + 4 =  {x}^{2}  +  {y}^{2}  + 4y + 4 \\  - 8y =  {x}^{2}  \\ y =  \frac{ - 1}{8}  {x}^{2}
C) is the correct answer

Mai biked 7 and 1/4 miles today, and Noah biked 3 5/8 miles. How many times the length of Noah's bike ride was Mai's bike ride?
Firdavs [7]

Answer:

2 times

Step-by-step explanation:

Mai biked 7\frac{1}{4} = \frac{29}{4} miles today and Noah biked 3\frac{5}{8} = \frac{29}{8} miles  today.

We are asked how many times the length of Noah's bike ride was Mai's bike ride.

Therefore, the length of Mai's bike ride was (\frac{29}{4} \div \frac{29}{8})  = 2 times the length of Noah's bike ride.  

Therefore, we will take option B will be correct. ( Answer )

What is the equation, in standard form, of a parabola that models the values in the table?
Vitek1552 [10]

Answer:

  b.  4x^2 + 3x - 6

Step-by-step explanation:

The values of f(x) for the extremes of x are more positive than the value of f(x) for the middle x, so we know the parabola opens upward. That eliminates choice D.

It is probably easiest to evaluate the other expressions to see which one matches the given f(x) values. For the purpose, it is usually easier to use the Horner form of the equation.

a. f(-2) = (3(-2) +4)(-2) -6 = -2(-2) -6 = -2 ≠ 4

b. f(-2) = (4(-2) +3)(-2) -6 = -5(-2) -6 = 4 . . . . matches the given data point

c. Because (b) matches, we know this one will not.

The appropriate choice is B.
