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 to find the area of 2 half circles and a rectangle
gladu [14]
Hello!

We use different formulas to calculate the areas of different shape.

RECTANGLE:

To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:

A = l × w

SEMICIRCLE:

Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:

A = 1/2 pi × r × r

Tip:

Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.
