2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12

1 + 5/12 = 12/12 + 5/12 = 17/12 = 1 5/12

2/3 + 3/4 = 1 + 5/12

A baseball team wants to collect at least 160 cans of food for an upcoming food drive. Team members brought 42 cans of food on M

Irina18 [472]

If they collect 65 on Monday, 42 on Wednesday and the rest on Friday, then we can write it down as:

65 + 42 + x ≥ 160
107 + x ≥ 160 / - 107 (both sides)
x ≥ 53

So the team needs to collect at least 53 cans on Friday.

Show that if the point with coordinates (x,y) is equidistant from the point (2,0) and the line y=−4, then y=1/8(x-2)²-2.

harkovskaia [24]

Answer:

The demonstration is showed below

Step-by-step explanation:

The distance betwenn two points is given by:

$d = \sqrt{(x2-x1)^2+(y2-y1)^2}$

If the point is equidistant from a point and a line, the distance must be equal. For the line let's select the point (x,-4), because the distance will be ortogonal, and is the small distance between a point and a line. So:

$\sqrt{(x-2)^2+(y-0)^2} = \sqrt{(x-x)^2+(y+4)^2}$
