Need help Fast!!!Part A: Max rented a boat that costs $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.
Write an equation in the slope-intercept form to represent the total rent (y) that Max has to pay for renting the boat for x days. (Hint.....use point slope form...then change to slope-intercept form) (6 points)

Part B: Write the equation obtained in Part A using function notation.(2 points)

(10 points)

Answers

Answer:

Part A:

The Standard Form equation of a line has the following formula:

Ax+By=C, where A, B, and C are integers, and A is non-negative.

We will assume that when renting a boat Sam paid fixed cost and rental charge per day.

y = the total rent

x = the number of days

Sam rented a boat at $225 for 2 days would mean:

y = 225 when x = 2 or if we plug into Ax+By=C:

2A + 225B = C since A is non-negative we divide both sides by A

2 + (B/A)225 = C/A

He rents the same boat for 5 days, he has to pay a total rent of $480 means:

y = 480 when x = 5 days

5A + 480B = C since A is non-negative we divide both sides by A

5 + (B/A)480 = C/A

Now we have:

2 + (B/A)225 = C/A

5 + (B/A)480 = C/A

Lets denote s = B/A  and t = C/A. Now we can write the following system of equations:

2 + 225s = t

5 + 480s = t

........

click here to see the system of equations solved for s and t

........

s = -1/85

t = -11/17 = -55/85

Now we can go back to:

B/A = -1/85 and C/A = -55/85

A = 85, B = -1, C = -55

The standard equation is:

85x - y = -55

Part B:

Using the equation 85x - y = -55 we solve for y

.......

click here to see the equation solved for y

........

y = 85x + 55

or in function notion y = f(x)

f(x) = 85x + 55

Part C:

Step-by-step explanation:

The expression is:-

f(h) = 16(h + 5) - 4

Step-by-step explanation:

To find the average you add the variables together

80+90+85+96=351

And then you take that number and divide by how many variables there are

351÷4=87.75 and you can round up to 88 if you want.

then we create a linear equation to get the value of b, and since the sum of the inner angles of the triangle = 180

b - 7 + b - 26 + (180 - 27 - b) = 180

B. x ≤ 29,000 and x ≥ 41,000
C. x ≥ 41,000 and x ≥ 29,000
D. x ≤ 41,000 and x ≤ 29,000

Answers

Answer:

A

Step-by-step explanation:

A is correct because if the minimum is 29,000 feet, x (the airplane altitutude) must be greater than or equal to 29,000 ft. Since the maximum is 41,000 feet, x must be less than or equal to that number.

The cost of 5 cans of pinto beans is $3.35.
elps
At this rate, how much do 11 cans of pinto beans cost?

Answers

Answer:

About $16.42

Step-by-step explanation:

Since you know the overall price of 5 cans of pinto beans is 3.35, you divide 5 by 3.35, to get the price of one can.

5 / 3.35 = 1.49, giving you the price of one can of pinto beans

You then multiply this number by 11, which gives you 16.42 (rounded)

Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?

The triangle is acute because 22 + 52 > 42.
The triangle is acute because 2 + 4 > 5.
The triangle is not acute because 22 + 42 < 52.
The triangle is not acute because 22 < 42 + 52.

Answers

Answer:

The triangle is not acute because 2^2 + 4^2 < 5^2

Step-by-step explanation:

2^2 is side a,

4^2 is side b,

5^2 is side c,

then

c^2 = a^2 + b^2 is right triangle

c^2 > a^2 + b^2 is obtuse

c^2 < a^2 + b^2 is acute

If we insert the numbers into the equation and square them:

c^2 = a^2 + b^2

25 = 4 + 16

25 > 20

This means the triangle is NOT accute, but obtuse

Therefore, it means the triangle is not acute, but obtuse

i.e.,

[tex]a^2 > b^2+c^2\\\\5^2 > 2^2+4^2[/tex]

What is the acute angle?

An angle is formed when two rays meet at a vertex. When this angle measures less than [tex]90[/tex] degree, it is termed an acute angle.

As per the Pythagoras theorem the triangle is acute only if the square of the longest side is less than the sum of the squares of the two smaller sides.

i.e., [tex]a^2 < b^2+c^2[/tex]

where [tex]a,b,c[/tex] are the lengths of the sides of a triangle.

So,

[tex]a^2=5^2\\b^2=2^2\\c^2=4^2[/tex]

Then,

The right triangle is [tex]a^2=b^2+c^2[/tex].

The obtuse triangle is [tex]a^2 > b^2+c^2[/tex]

The acute triangle is [tex]a^2 < b^2 + c^2[/tex]

i.e.,

[tex]5^2 = 2^2+4^2\\\\25=4+16\\\\25 > 20[/tex]

Hence, this means the triangle is not acute, but obtuse.

Let a number = X

 9-1/3x = 7      

Step-by-step explanation:

Let the number be denoted by x.

Now, we are given a word phrase as follows:

One-third of a number less than nine is equal to seven.

Now this word phrase could be mathematically expressed as a equation by:

 one-third of x is: 1/3 x

and this number less than 9 is given by:

 9-1/3x

Now, this number is equal to 7.

i.e. we finally have:

 9-1/3x = 7

Forexample, water can evaporate when it absorbs energy from sunlight or from surroundingair, water, or land. When water condenses to form clouds, the water molecules releaseenergy to the surrounding atmosphere.As water moves, it transfers energy from one location to another. For example, asa warm surface current in the ocean flows to a colder polar region, thermal energy fromthe equator is transported toward Earth's poles. When the warm water reaches areaswhere the air is colder, some energy in the warmer water is released into the cooler air.These energy transfers between the ocean and the atmosphere greatly influence Earth'sweather and climate.current27.
