Rewriting input as fractions if necessary:
7/1, 343/1
For the denominators (1, 1) the least common multiple (LCM<span>) is </span>1.
Therefore, the least common denominator (LCD<span>) is </span>1.

Answer: y = -4x - 4
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.
First, find the slope. To find the slope, use this "formula" : ![slope=\frac{rise}{run} =\frac{y1-y2}{x2-x1}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7Brise%7D%7Brun%7D%20%3D%5Cfrac%7By1-y2%7D%7Bx2-x1%7D)
Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:
![\frac{4--4}{-2-0} =\frac{4+4}{-2} =\frac{8}{-2}=-4](https://tex.z-dn.net/?f=%5Cfrac%7B4--4%7D%7B-2-0%7D%20%3D%5Cfrac%7B4%2B4%7D%7B-2%7D%20%3D%5Cfrac%7B8%7D%7B-2%7D%3D-4)
Then, pick any point to plug into the equation. Let's use (0,-4)
Finally, plug everything into the equation:
y - - 4 = -4(x - 0)
y + 4 = -4x
y = -4x - 4
Answer:
15/4
Step-by-step explanation:
Equation: 40(5+x)=70*5+0x
Solve:
200+40x=350
40x=150
x = 15/4
15/4 gallons is the answer.
