Hello,
The line is passing througth
(-1,1) and (1,4).

y-4=(4-1)/(1+1)(x-1)
==>y=3/2(x-1)+4
==>2y=3x-3+8
==>3x-2y=-5

The endpoints of a diameter of a circle are (-4,

aliya0001 [1]

<u>Answer:</u>

<u>Explanation:</u>

x = -4 + (12 - (-4))/2

x = -4 + (12+4)/2

x = -4 + 16/2

x = -4 + 8

x = 4

y = 2 + (10 - 2)/2

y = 2 + 8/2

y = 2 + 4

y = 6

the coordinates of the center of the circle: (4, 6)

Match each set of points with the slope of the line formed by the ordered pairs.

Maksim231197 [3]

Answer:

(0,7) and (2,4) go to slope =-3/2

(1,-3) and (-1,-3) go to zero slope

(0,0) and (2,1) go to slope =1/2

(0,-1) and (2,-5) go to slope =-2

and (-1,3) and (-1,-3) go to no slope

The distance between Lincoln, NE, and Boulder, CO, is about 500 miles. The distance between Boulder, CO, and a third city is 200

GenaCL600 [577]

We know that

The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)

Let

A------> Lincoln, NE

B------> Boulder, CO

C------> third city

we know that

in the triangle ABC

AB=500 miles

BC=200 miles

AC=x

Applying the Triangle Inequality Theorem

1) 500+200 > x------> 700 > x------> x < 700 miles

2) 200+x > 500----> x > 500-200------> x > 300 miles

the solution for x is

300 < x < 700

the interval is------> (300,700)

the possible distances, d, in miles, between Lincoln, NE, and the third city, are in the range between 300 and 700 miles
