<h2>3x-4y-15=0 </h2><h2>Geometric figure: Straight Line</h2><h2> Slope = 1.500/2.000 = 0.750</h2><h2> x-intercept = 15/3 = 5</h2><h2> y-intercept = 15/-4 = -3.75000</h2><h2>Step by step solution :</h2><h2>Step 1 :</h2><h2>Equation of a Straight Line</h2><h2> 1.1 Solve 3x-4y-15 = 0 </h2><h2 /><h2>Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK). </h2><h2 /><h2>"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.</h2><h2 /><h2>In this formula :</h2><h2>y tells us how far up the line goes</h2><h2>x tells us how far along</h2><h2>m is the Slope or Gradient i.e. how steep the line is</h2><h2>b is the Y-intercept i.e. where the line crosses the Y axis</h2><h2>The X and Y intercepts and the Slope are called the line properties.

We note that for x=0, the value of y is -3.750 and for x=2.000, the value of y is -2.250. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.250 - (-3.750) = 1.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)</h2><h2> Slope = 1.500/2.000 = 0.750 </h2><h2>Geometric figure: Straight Line</h2><h2> Slope = 1.500/2.000 = 0.750</h2><h2> x-intercept = 15/3 = 5</h2><h2> y-intercept = 15/-4 = -3.75000</h2><h2>Hope This Helps!!!</h2>

Hello there! With the values of "x" and "y", they fill in the parenthesis. -3 + 5 is 2, because adding into a negative makes the number go up, or just simply subtracting 3 from 5 works as well. However, there is a 0 beside it, so we raise 2 to the 0 power. Anything that is raised to the 0 power is always equal to 1. And there is no other part of the question, so 1 is our answer. The answer is C: 1.

A company has two separate offices. One office has a color printer and the other office has a black and white

Vitek1552 [10]

Answer:

the larger of two printers being used to print the payroll for a major corporation requres 40 min. to print the payroll.So the smaller printer's payroll printing rate is

1 payroll per x min or or

>>...After both printers have been operating for 10 min, the larger printer malfunctions...<<

So the fraction of the payroll that the larger printer did in the 10 minutes

is = payroll.

A rectangular card has an area of 120 over 1\4 square inches. The card is 6 over 1\2 inches wide. How long is the card???? if u

Anika [276]

The area is 120/(1/4) or 120 x 4 or 480 square inches
the width is 6/(1/2) or 6 x 2 or 12 inches
to find the length, divide the area by the width
480/12= 40
40 inches
Hope this helps :)
