Answer:
330=40x+50
Step-by-step explanation:
then you would -50 from both sides
280=40x
then you would divide both sides by 40 to isolate x
7=x
so that means it would take 7 weeks
Answer:
3.456E + 14= 
Step-by-step explanation:
The river discharges
cubic feet of water into the Pacific Ocean each second.
There are 86,400 seconds in one day.
Amount of water discharges each day

Since this differs from what you have, I will explain the scientific notation.
3.456E + 14 simply means 
The options are not well laid out but you can pick the appropriate option.
1. To find the x-intercept, replace y in the equation with 0, then solve for x.
... To find the y-intercept, replace x in the equation with 0, then solve for y.
If the equation is easily put into the form
... x/a + y/b = 1
Then the x-intercept is "a" and the y-intercept is "b".
2. Let's graph 3x+4y = -12.
If we divide the equation by -12, we can put it into the form
.. x/(-4) + y/(-3) = 1
This equation has x-intercept -4 and y-intercept -3.
(If you know the intercepts, you can simply draw the line through them to graph your linear equation.)
5/10 because it is equivalent to 1/2
So the answer is 5/10
