Find the equation of the line that passes through (3,-2) and whose m=1/2

y=m x+c

If m=\frac{1}{2}

Then:

y=\frac{1}{2} x+c

Sub in the coordinates given to you:

-2=\frac{1}{2} *3+c

Now:

\frac{1}{2}*3=1.5

Move 1.5 to the other side of the equation and flip the sign.

-2-1.5=c

Therefore, c = -3.5.

Replace in the formula (y=mx+c):

y=\frac{1}{2}x-3.5

There is your answer.

sveticcg [70]

Answer:

The system of inequalities is

2x+10y\leq 40

x+y\geq 5

The solution in the attached figure

Step-by-step explanation:

<u><em>The question is</em></u>

Write a system of linear inequalities.

Le

x ---> number of scarves knitted per week

y ---> number of knitted sweaters per week

we know that

Mary would like to spend no more than 40 hours per week knitting

The word "No more" means "less than or equal to"

so

2x+10y\leq 40 ----> inequality A

Mary would like to knit at least 5 items per week

The word "at least" means "greater than or equal to"

x+y\geq 5 ----> inequality B

Solve the system by graphing

The solution is the triangular shaded area

see the attached figure

One end of a ramp is raised to the back of a truck 5 feet above the ground. 1 point
sveta [45]

Answer:

38.7°

Step-by-step explanation:

You are basically looking at a triangle with a 90° angle (check picture).

Since we are looking for the ramp's angle and are given the length of the opposite and the hypothenuse, we have to solve the following equation:

sin (\alpha) = opposite / hypothenuse= 5 ft/8ft

which is equivalent to

\alpha = sin^{-1}(5/8)\approx 38.7\deg

OverLord2011 [107]

Answer:

  ai) 73000 gal/yr

  aii) $730 per year

  b) 1000 days

Step-by-step explanation:

ai) The water usage per day is ...

  (4 showers/day)(10 min/shower)(5 gal/min) = 200 gal/day

Then the usage per year is ...

 (200 gal/day)(365 days/yr) = 73,000 gal/yr

__

aii) The cost of electricity is the cost of heating half the water usage, so is ...

  (0.20 kWh/gal)(1/2)(73,000 gal/yr)($0.10/kWh) = $730/yr

__

b) The current daily cost of electricity for heating water is ...

  ($730/yr)/(365 days/yr) = $2/day

If the cost is cut in half, it will be $1 per day. That means the savings is $1 per day, so it will take 1000 days to recover the $1000 initial cost. (Effectively, the average cost for the first 1000 days is the same as if the water heater had not been replaced.)
