19 or if ur talking about the meme 21 XD
Answer:
-5
Step-by-step explanation:
Once you get y alone the equation will look like this y=-7/4x-5.
The slope intercept form dictates that y=mx+b, with b being the y-intercept, so -5 is b, therefore the y intercept.
Answer:
B.
Step-by-step explanation:
It doesn't make sense for either x or y to be negative because we are talking about x representing the number of acres and y representing another number of acres and that they should add up to no more than 400.
So I'm not going to look at A or C.
B looks good 250+150=400
D almost looks good 1+400=401; the problem with this answer is that is more than 400
We'll use 'x' to represent that 'something.
7/9x=640.
Divide each side by 7/9 to isolate 'x'.
x = 822 6/7.
