Answer:
First, put it into slope/intercept form so you can see what you've got.
"Slope/intercept form" is y = everything else .
So that means you have to take the equation you have and "solve it for 'y' ".
2y - 10x = 20
Add 10x to each side: 2y = 10x + 20
Divide each side by 2 : y = 5x + 10
And that's exactly the information you need to graph it. On your graph,
mark a little dot on the y-axis at 10, and draw a line through that dot
with a slope of 5.
Answer:
The equation is y = -2/5x + 4
Step-by-step explanation:
First we have to find the slope of the line. In order to do so, solve the first equation for y.
2x + 5y = 20
5y = -2x + 20
y = -2/5x + 4
This gives us a slope of -2/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.
y - y1 = m(x - x1)
y - 6 = -2/5(x - -5)
y - 6 = -2/5(x + 5)
y - 6 = -2/5x - 2
y = -2/5x + 4
15/4= 3.75, so they would need to purchase more milk after 3 days, they would only have 3 liters for their 4th day
Answer:
its a estamite just guess
Step-by-step explanation:
First differences are ...
41 -39 = 2
43 -41 = 2
45 -43 = 2
These are all the same, so 2 is the common difference of the arithmetic sequence beginning with 39.
