If you're drawing the graph by hand, there are a couple of strategies that can be useful.
The first equation is almost in slope-intercept form. Dividing it by 2 will put it in that form:
y = 2x -4
This tells you that the y-intercept, (0, -4) is a point on the graph, as is the point that is up 2 and right 1 from there: (1, -2). A line through those points completes the graph.
__
The second equation is in standard form, so the x- and y-intercepts are easily found. One way to do that is to divide by the constant on the right to get ...
x/2 +y/3 = 1
The denominators of the x-term and the y-term are the x-intercept and the y-intercept, respectively. If that is too mind-bending, you can simply set x=0 to find the y-intercept:
0 +2y = 6
y = 6/2 = 3
and set y=0 to find the x-intercept
3x +0 = 6
x = 6/3 = 2
Plot the intercepts and draw the line through them for the graph of this equation.

Here, we have suggested graphing strategies that don't involve a lot of manipulation of the equations. The idea is to get there as quickly as possible with a minimum of mistakes.

The answer to your question is below
Step-by-step explanation:
See the picture, please
In the first picture, we notice the initial amount of brownies (7/10), 7 brownies in a pan for 10 brownies.
After Tyreese bought 2/5 (7/10 - 2/5 = 3/10) there are 3 brownies left.
So in the picture, we notice only 3 brownies in a pan for 3 brownies.
Answer:
fully factored form = 3(x-4)(x+8)
Step-by-step explanation:
first you factor 3 out
3(x^2+4x-32)
then factor it
3(x-4)(x+8)
Okay. 40% of 50 is 20. 2 * 20 is 40. The other 30 tables seat 4 people. 4 * 30 is 120. 120 + 40 is 160. There are 160 seats in the restaurant.
