B, C, A because A is the steepest line, meaning it fills up the quickest and B is the least quick because it has the least steep line according to the graph.

Hope this helped!

First question. The midpoint of SR is...

Blizzard [7]

The formula of a midpoint SR:

$M\left(\dfrac{x_S+x_R}{2},\ \dfrac{y_S+y_R}{2}\right)$

We have

S(4, 1) and M(7, -5)

Substitute:

$\dfrac{4+x_R}{2}=7\qquad|\cdot2\\\\4+x_R=14\qquad|-4\\\\x_R=10\\\\\dfrac{1+y_R}{2}=-5\qquad|\cdot2\\\\1+y_R=-10\qquad|-1\\\\y_R=-11$

<h3>Answer: R(10, -11)</h3>

Which represents the solution(s) of the system of equations, y = x^2 - 6x + 8 and y = -x + 4? Determine the solution set by grap

Len [333]

Answer:

(1, 3) and (4,0)

Step-by-step explanation:

The quadratic function is $y=x^2-6x+8$

We can rewrite in the form $y=(x-3)^2-1$

The graph is obtained by shifting the parent quadratic function 3 units right and 1 unit down to obtain the parabola shown in the attachment.

The straight line also have equation $y=-x+4$

The slope is -1 and y-intercept is 4.

We can easily graph this straight line on the same graph as shown in the attachment.

The two graphs intersected at (4,0) and (1,3).

The solution set is therefore {(x,y)|x=4,y=0 or x=1,y=3}

How do i solve this in the quadratic formula?

liraira [26]

Firstly mines 2x for 2 side
And combine 1 for 2 side
Result 6x^2+17x+5
So
(3x+1)(2x+5)=0
X=-1/3 or x=-5/2

PLEASE HELP, WILL MARK BRAINLIEST!

Leokris [45]

Answer:

8,5 feet

Step-by-step explanation:

The equation of the form

x² + y² = (r)²

Is the equation of the circumference

We have for the pool:

x² + y² = 2500 ⇒ x² + y² = (50)²

And for the outside edge of the footpath

x² + y² = 3422,25 ⇒ x² + y² = (58,5)²

So we obtain the radius of each circumference

For the outside edge of the pool r₁ = 50 feet

For the outside edge of the footpath r₂ = 58,5 feet

Then the width of the footpath is 58,5 - 50 = 8,5 feet
