the triangle mnp is a dilation of triangle jkl
Ok so standard form is a bit tricky, but I’ll help explain
Here’s and example:
If you have 2x+5y=10 here is how you would solve it
First you divide the x value by what the number is equal to (in our example, 10), and then we get 10/2 is 5. So now we know that
x is equal to five
Keep that in mind. Now we just have to do the same thing for the y value. 5/10 is 2, so you know that
y is equal to two
NOW you put those two together, and graph on the intercepts (the positions on the y and x axis where the lines intercept)
You would put a line on the x axis at 5, and on the y axis at 2
If you have any questions, you can ask
You need to add 2 L of the 75% mixture to get a mixture that is 60% antifreeze.
<h3>What is an antifreeze?</h3>
Anti freeze is a substance that is added in order to prevent a liquid from freezing. An antifreeze is usually an ionic substances that is used during the winter to prevent the freezing of a liquid.
Now;
Forming the equation;
0.75*x+0.5*3=0.6(3+x)
Hence;
0.75*x+1.5=1.8+0.6x
Therefore;
0.75x-0.6x=1.8-1.5
We obtain;
0.15x=0.3
Then;
x=2L
