Answer:
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
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
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
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
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

Answer:
y-intercept: (0,3); x-intercept: (12,0)
Step-by-step explanation:
The y-intercept is in a line where x = 0, so to find it, you can plug in 0 for x in the equation.
y = -¹/₄(0) + 3
y = 0 + 3
y = 3
So when x = 0, y = 3, therefore the y-intercept is (0,3)
The x-intercept is when y = 0, so plug in 0 into y
0 = -¹/₄x + 3
-3 = -¹/₄x
x = 12
So when = 0, x = 12, therefore the x-intercept is (12,0)
Answer:
(0,3)
Step-by-step explanation:
y = -1/4 + 3
The intercept is (0,3)

-- It can't be a right triangle, because the squares of the 2 short sides
don't add up to the square of the longest side.
-- It can't be isosceles, because every isosceles triangle has 2 sides
the same length.
-- It can't be equilateral, because every equilateral triangle has all 3 sides
the same length.
-- So, out of the choices you've listed, this is a scalene triangle.
A scalene triangle is simply one whose sides are all different lengths.

The required time, that turtles take to walk 1 1/4 miles is 20 hours.
What is speed?
Speed is defined as when an object is in motion, the distance covered by that object per unit time is called speed.
here,
Sammy the turtle can walk 1/8 of a mile in an hour.
Speed = 1/8 mils per hour
Time = distance / speed
Time = 1 1/4 / 1/8
Time = 5/4 × 8/1
Time = 20 hours
Thus, the required time, that turtles take to walk 1 1/4 miles is 20 hours.
