At the dog show there are 4 times as many boxes as spaniels. if there are a total of 30 dogs how many dogs are spaniels

1 answer:

4 0

So the equation would be 4x+x=30. So since they have the same variable, x and 4x, you add them together to get 5x=30. Then you divide by both sides and get x=6. So there are 6 spaniels.

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:

<u><em>The correct question is</em></u>

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

<em>Verify each case</em>

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

the baker's at healthy Bakery can make 250 Bagels in the five hours how many bagels can they bake in 16 hours what was the rate

kolbaska11 [484]

Unit rate would be 50 because 250÷5=50, so the answer would be (250×3)+50, witch is 800.

MATH.... TRIANGLE JKL HAS VERTICES...

7nadin3 [17]

<h3>Answer: Choice (d)</h3>

Explanation:

To reflect over the y axis, we apply this rule

$(x,y) \to (-x,y)$

which says to flip the sign of the x term but keep the y coordinate the same.

So that means something like J(-2,5) becomes J ' (2, 5). The other points are handled in the same fashion and that leads us to choice (d). Points on the y axis will stay where they are.
