Which equation represents a parabola that opens upward, has a minimum value of 3, and has an axis of symmetry at x= 3?

Ilya [14]

Answer:

$y=(x-3)^2+3$

Step-by-step explanation:

The correct question is

Which equation represents a parabola that opens upward, has a minimum value of y=3, and has an axis of symmetry at x= 3?

Verify each case

case 1) we have

$y=(x+3)^2-6$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (-3,-6)

The minimum value of y=-6 ----> is not ok

The axis of symmetry is x=-3 ----> is not ok

case 2) we have

$y=(x+3)^2+3$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (-3,3)

The minimum value of y=3 ----> is ok

The axis of symmetry is x=-3 ----> is not ok

case 3) we have

$y=(x-3)^2-6$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (3,-6)

The minimum value of y=-6 ----> is not ok

The axis of symmetry is x=3 ----> is ok

case 4) we have

$y=(x-3)^2+3$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (3,3)

The minimum value of y=3 ----> is ok

The axis of symmetry is x=3 ----> is ok

OLga [1]

Answer:

There are 60 toddlers in the preschool class

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Percentage of the toddlers in a preschool class drink water with their lunch = 5

Number of the toddlers in a preschool class drink water with their lunch = 3

2. How many toddlers are in the class?

We'll solve the question, using the Direct Rule of Three, this way:

Percentage Toddlers

5 3

100 x

*******************************

5x = 3 *100

5x = 300

x = 300/5

x = 60

Answer:

HOWEVER: "Less Than" is usually depicted as a dashed line at the border. and there MUST be an OR between these two equations to include all of the blue area. An "and" there would exclude the area between the edge lines.

Step-by-step explanation:

2x + y < 10

y < -2x + 10

3x + 2y < 12

2y < -3x + 12

y < -1.5x + 6
