Step-by-step explanation:

let us attend to each cases one after the other. each relationship is in bold in parenthesis

1. The cost of hiring a mover is based on the distance traveled and the total weight of the objects moved. (positive or direct proportional relationship)

2. The amount of time needed to paint a house decreases as the number of painters increases.(Negative or inverse relationships)

3. The income of a worker who gets paid an hourly wage depends on the number of hours worked positive or direct proportional relationship)

The picture below shows a container that Jeff uses to freeze water: A cylinder is shown with base diameter of 8 centimeters and
Butoxors [25]
Okay, first we need to figure out what one would make. We need to figure out the area of the base x height. The diameter is 8 so we will cut that to 4 so we can do piR2! 3.14x16 would be 50.24. Then we mutiply that by 10 to get 502.4cm3! Okay, now we would divide 2000/502.4 to find out how many times we would have to make the containers to get to 2000. The answer is 3.98, which we will have to round up since its asks for the minimum and you cant make a container 3.98 times. So the answer is 4!

Graph the following lines and write the equation in slope-intercept form. With y intercept of −3 and an x intercept of −4.5.
makvit [3.9K]

Answer:

y=-\frac{2}{3}x-3

Step-by-step explanation:

To write the equation of a line we need 2 points. We know:

  • If the y-intercept of the line is -3 then the point is (0,-3).
  • If the x-intercept of the line is -4.5 then the point is (-4.5,0).

Using these two point, we will find the slope and then substitute it into the point slope form y-y_1=m(x-x_1) with a point.

Slope: m=\frac{0--3}{-4.5-0}=\frac{0+3}{-4.5}=\frac{3}{-4.5}=-0.6667

This decimal is -2/3. We will now substitute -2/3 and (0,-3) into the point slope form.

y--3=-\frac{2}{3}(x-0)\\y+3=-\frac{2}{3}(x)\\y+3=-\frac{2}{3}x\\y=-\frac{2}{3}x-3

1. The county fair charges $2.50 per ticket for the rides. Henry bought 15 tickets for the rides and spent a total of $55.50 at
ehidna [41]

Answer and explanation

a is $18.00 because Z is a constant

b is y=2.50x+18.00

c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute

that leads to 55.50 =2.50(15)+z

and the untimely z = 18.00 dollars .
