Answer:

Fourth option y = x²

Step-by-step explanation:

It is clear from the graph that parabola passes through origin, which is it's vertex and line of symmetry is y-axis.

So the equation of the parabola will be y = (x - 0)² + 0

This equation of the parabola is in the vertex form [ y = (x - h)² + k]

Therefore, equation of the parabola will be y = x²

This equation is true for the given values of x and y in the table.

For (-2, 4) ⇒ 4 = (-2)²

For (-1, 1) ⇒ 1 = (-1)²

Fourth option y = x² is the answer.

REY [17]

The question is incomplete as the cost price isn't given. However, taking the cost price as x :

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

A car costs$cents when new. It was sold for four fifths of its cost price. How much money was lost on the car.

Let :

Cost price when new = x

Cost price when sold = 4/5 * cost price when new

Cost when sold = 4/5 of x = 4x/5

Amount of money lost on the car = (Cost price of car when new - Cost of car when sold)

Hence,

Amount of money lost on the car = (x - 4x/5)

x - 4x/5 = (5x - 4x) / 5 = x / 5

To obtain the exact price, kindly input the omitted cost when new for x.

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r
Inessa05 [86]

Answer:

r = 43.35

Step-by-step explanation:

Given

Current\ Rent = r

Increment = 15\%

New\ Rent = \$51

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

\%Increment  = \frac{New\ Rent - Current\ Rent}{Current\ Rent}

Substitute values in the above equation

15\% = \frac{51 - r}{51}

Cross Multiply

51 - r = 15\% * 51

Convert percentage to decimal

51 - r = 0.15 * 51

51 - r = 7.65

And the value of r\ is\ calculated\ using:

r = 51 -7.65

r = 43.35

Hence, Cody's current rent is $43.35 monthly
