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
The slope is 4/5
You would get the equation in y = mx + b form
m (slope) will be the coefficient of x
Answer:
pretty sure it's B
Step-by-step explanation:
domain is x numbers and that has all the x numbers in it
The area of a circle is pi times the radius squared
Answer:
21+3x
Step-by-step explanation:
Expand this:
3(7+x)
So it becomes:
21+3x
