Original System: x - 2y = 0; 5x + 2y = 24

In order to graph this system, you need to find the slope of each line and the y intercept of each line. The easiest way to do this is to put both equations into slope intercept form, which is y = mx + b

     x - 2y = 0 
   - x         - x 
-------------------
   2y = -x + 0
 ------  ----  ----
    2      2    2

y = -1/2x

For this equation, the slope is 1. The x intercept is 0. 


     5x + 2y = 24
   - 5x          - 5x
------------------------
     2y = -5x + 24
   ------  ------ ------
      2       2      2

y = -5/2x + 12

In this equation, the slope is -5/2 and the y intercept is 12.

When you plug in these equations on Desmos, look at the exact point where the lines intersect. This will be your final answer to the system of linear equations.

Which expression lists the three consecutive integers starting with a number x? A. x, x + 2, x + 4 B. x + 1, x, x + 2 C. x – 1,
Vika [28.1K]

Consecutive integers are like 1, 2, and 3. They are in a row. Think about plugging numbers in for x. 1 and 1+2 are not consecutive, so A is not the answer. B and C don't start with x, so they aren't the answer. That leaves D, because it starts with x, then goes to x+1, and then to x+2. These are consecutive, because if x was 1, it would be 1, 2, 3.

The answer is D.

I hope this helps :)

Help anyone I don’t understand this ????

The answer would be 0
You combine the first 2 “K” and that would make it k squared meaning it equals to 1 so now it’s 3k minus 3k so 0

Is 4 over 6 greater or less than 12 over 12
weqwewe [10]
To compare fractions with unlike denominators convert them to equivalent fractions with the same denominator. Compare fractions: If denominators are the same you can compare the numerators. The fraction with the bigger numerator is the larger fraction.

How do you determine a scale factor for two similar figures? <br> 15 points
mr_godi [17]

the scale factor or ratio of two similar figures, will be the same as the ratio of their perimeter, or even the ratio of two corresponding sides.


for example, we have say, an irregular octagon with a perimeter of say 13, and a similar octagon with a perimeter of 39, then


\bf \cfrac{\textit{small octagon}}{\textit{large octagon}}~\hspace{5em}\cfrac{perimeter}{perimeter}\implies \cfrac{13}{39}\implies \stackrel{simplified}{\cfrac{1}{3}}~\hfill \stackrel{\textit{scale factor}}{1:3}


which is another way to say, the smaller is 1/3 of the larger one, or the larger one is 3 times as the smaller one.
