Answer:
2x - y - 4 = 0
Step-by-step explanation:
Here, (x1,y1) = (0,4) and m = -2
Point-slope form of the equation of a line is
y - y1 = m(x - x1)
So,
y - 4 = -2(x - 0)
y - 4 = -2x
2x - y - 4 = 0 is the equation of the line.

Answer:
Unit rate of money spent to hours = $4 per hour
Step-by-step explanation:
We have given,
Amount spent:
on purchasing water=$9.00
on protein bars = $5.00
on peanuts = $3.00
So total amount spent on purchasing = $9 + $5 + $3 = $17
They start hiking at 11:30am and finish the hike at 3:45pm.
Total number of hiking hours = 4 hours and 15 minutes = 4.25 hours
We need to find rate of money spent per hours.
i.e. Unit rate of money spent = ![\frac{Total money spent}{Total number of hours}](https://tex.z-dn.net/?f=%5Cfrac%7BTotal%20money%20spent%7D%7BTotal%20number%20of%20hours%7D)
Unit rate =![\frac{17}{4.25}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B4.25%7D)
Unit rate = 4 dollar per hour or $4 per hour
Answer: X1 = -1 X2 = 7/5
Step-by-step explanation:
move the constant to the left-handed side, write -2x as a difference, factor out 5x from the expression, then factor out x + 1 from the expression. when the product of factors equals 0, at least one factor is 0. lastly, solve for x.
The equation would be 90/18 which would give you the cost of 5 dollars per rose
