One way to do it would be to forget about labels. So basically, 3*6=? Then just add the negative sign. (This doesn't work for all equations! Only ones like these) :D hope this helped :)

There were 45 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 3/5 of the remaining runners dropped out. How many runners finished the race?

Answers

the price of the printer was reduced from $400 to $180 . what was the percent decrease? amount of increase or decrease divided by amount of original multiplied by 100

Answers

400 - 180 = 220

220/400 = 0,55

0.55 x 100  = 55

So the percentage of decrease would be : 55 %

C. Use the graph to estimate the solution to the system of equations.
Help??

Answers

A. The first equation in slope-intercept form is y = -0.5x + 3. The second equation in slope-intercept form is y = 0.6x - 2.

B. The graph of the two equations is attached below.

C. The solution of the system of equation is (4.545,0.727)

A. To write the equations in slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate "y" on one side of each equation.

1. 2x + 4y = 12

First, isolate "y" by subtracting 2x from both sides:

4y = -2x + 12

Next, divide both sides by 4 to get "y" by itself:

y = (-2x + 12) / 4

Simplify the equation:

y = -0.5x + 3

So, the first equation in slope-intercept form is y = -0.5x + 3.

2. 3x - 5y = 10

First, isolate "y" by subtracting 3x from both sides:

-5y = -3x + 10

Next, divide both sides by -5 to get "y" by itself:

y = (-3x + 10) / -5

Simplify the equation:

y = 0.6x - 2

So, the second equation in slope-intercept form is y = 0.6x - 2.

B. To graph the pair of linear equations, plot the y-intercept (where x = 0) and use the slope to find other points.

1. Graph the equation y = -0.5x + 3:

Plot the y-intercept at (0, 3).

Use the slope -0.5 to find another point; for example, if x = 2, then y = -0.5(2) + 3 = 2.

2. Graph the equation y = 0.6x - 2:

Plot the y-intercept at (0, -2).

Use the slope 0.6 to find another point; for example, if x = 3, then y = 0.6(3) - 2 = 0.

C. To estimate the solution to the system of equations, look for the point where the two lines intersect. This point represents the x and y values that satisfy both equations simultaneously. From the graph, we can interpret that the solution of the system of equation is (4.545,0.727)

1)     This format that the two equations are in is called Standard Form, and it's formula is Ax+By=C. Slope-Intercept Form is another form in which linear equations can be written. It's expressed as y=mx+b. See how in SIF (Slope intercept form), the "y" is isolated? All you have to do is isolate the "y" in both equations given to you.

2x+4y=12
-2x       -2x
4y=-2x+12
/4           /4
y=-1/2x+3

3x-5y=10
-3x       -3x
-5y=-3x+10
/-5         /-5
y=3/5x-2

2)     To graph SIF, you need to know what each aspect of the equation is. The formula is y=mx+b.

m stands for slope. A great way to remember it is rise/run (rise over run). Basically, the numerator in "m" is how far up you go to graph each point, and the denominator is how far left or right you go (remember, left is negative, right is positive). Let me give you an example. y=3/5x. In this formula, to graph each point, on the line, you'd go up 3, and to the right 5, then plot a point, then up 3, right 5, plot another one... you get it. What if the equation was y=3x though? The slope would be 3/1, or up 3, right one.

You know how to plot the points, but what coordinate do you startat? That's where the Y-Intercept comes into play. The Y-Intercept is basically where the line crosses the Y-axis. The b in the SIF formula is the y-intercept, and where you plot your very first coordinate on the line. If the SIF equation was y=1x+3, your first coordinate would be on the y axis, at an elevation of 3. Since the y-axis is at x=0, the coordinate would be (0,3). 

3)     Look at the graph now. Where do the lines cross? The x should be somewhere between 4 and 5, and the y is somewhere between 1.5 and 2. Therefor, your "estimation" should be something like (4.5,1.75)
