For the line segment whose endpoints are X(1, 2) and Y(6, 7), find the x value for the

finlep [7]

Answer:

3) 2.7

Step-by-step explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ can be determined by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Since the points are X(1, 2) and Y(6, 7). The distance between the two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(6-1)^2+(7-2)^2}=\sqrt{50}$

the x value for the point located 1/3 the distance from X to Y,

$x=\frac{x_2-x_1}{3}=\frac{6-1}{3}=1.7$

The x value = $x_1+1.7 = 1+1.7 = 2.7$

A grocery store sells 5 bottles of water for $3 and 15 bottles of water for$8 is the cost of the water proportional to the numbe

egoroff_w [7]

Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
