Mathematics

aleksley [76]3 years ago

Answer:

y=-2x+3

Step-by-step explanation:

Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.

The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.

Begin by plugging in what we know.

(3) = (-2)(0) + b

3 = 0 + b

3 = b

Plug in the y-intercept (b) and slope (m)

y=-2x+3

How many lengths of wire, each 3 3/4 inches. long can be cut from a 25-ft roll?
lianna [129]

Answer:

80 pieces of wire.

Step-by-step explanation:

It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.

Change 3 3/4 to a decimal

3.75

Change the 25 foot roll to inches.

25 feet * 12 inches / foot  = 300 inches.

Now how many pieces of wire do we get.

1 piece of wire/3.75 inches = x pieces of wire / 300 inches

3.75 * x = 300

3.75 * x / 3.75 = 300 / 3.75

x = 80
