Answer:
4x+2y = 14 The original equation
2y = 14-4x Subtract 4x from both sides
2y = -4x+14 Rearrange so x is first
y = -2x+7 Divide everything by 2
Explanation:
The steps above practically explain everything needed, so there's not much to add. The standard form is Ax+By = C while slope intercept form is y = mx+b
In the case of y = -2x+7, we have a slope of m = -2 and y intercept of b = 7. This means (0,7) is one point on the line. Use the slope to move down two and to the right one unit to arrive at (1, 5) as another point on this line.
There are 5,280 feet in a single mile.
Which is equivalent to 1,760 yards.

Answer:
-$2.32
Step-by-step explanation:
Give that
The selling price per ticket is $9
And the number of tickets sold is 500
So,
There is one grand prize, three $300 second prize, and eleven $40 third prizes
We need to find out the expected value of the profit
![= \frac{1}{500} \times 2000 + \frac{3}{500} \times 300 + \frac{11}{500} \times 40\\\\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B500%7D%20%5Ctimes%202000%20%2B%20%20%5Cfrac%7B3%7D%7B500%7D%20%5Ctimes%20300%20%2B%20%5Cfrac%7B11%7D%7B500%7D%20%5Ctimes%2040%5C%5C%5C%5C)
= 4 + 1.8 + 0.88
= 6.68
Now the expected profit is
= $6.68 - $9
= -$2.32
Answer: Esy the answer is; C.
Step-by-step explanation:
The higher the negative value the less or lower the number is.
CONFUSING Right? XD
