Line passes through (2, -1) and slope of 1/3

<h3><u>Step 1</u></h3>

y = mx + b,  Identify:  x = 2, y = -1, slope: \sf \frac{1}{3}

<u>insert following values</u>

\rightarrow \sf -1 = \dfrac{1}{3} (2) + b

<u>multiply</u>

\rightarrow \sf -1 = \dfrac{2}{3}  + b

<u>switch sides</u>

\rightarrow \sf b = -1 - \dfrac{2}{3}

<u>subtract</u>

\sf \rightarrow b = -\dfrac{5}{3}

<u>convert to mixed fraction</u>

\sf \rightarrow b = -1\dfrac{2}{3}

<h3><u>Step 2</u></h3>

y = mx + b,  m = \sf \frac{1}{3}, b = -1\frac{2}{3}

<u>insert following values</u>

\rightarrow \sf y =  \dfrac{1}{3} x -1\dfrac{2}{3}

at an amusement park a person spends $30 on admission and food and then goes on r number of rides that cost $2 each
stepladder [879]
The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.

Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r

Total spend, s(r): 30 + 2r

Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5  ----- this is the function notation

Standard form: s(r) is the dependent variable = s

s = 30 + 2r => s - 2r = 30 =>

s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form

I don’t understand this I’ve tried a lot of answers that made sense to me but none are right, can someone please help me?
Ray Of Light [21]

Answer:

-4

Step-by-step explanation:

Low tide is 1 ft below average water level.

High tide is 5 ft higher than low tide.

High tide is 5 ft higher than low tide. Start at low tide. Use 1 ft of the 5 ft to go up to average water level. You still have 4 ft more to go to high tide. That means high tide is 4 ft above average water level. Then, the average water level is 4 ft below high tide. A height below another height is is a negative number of feet from that height. Since the average water height is 4 ft BELOW high tide, then relative to high tide, the average water level is -4 ft.

Hey!
noname [10]

Answer:

A. Cylinder + cone

<u>Volume is the sum of volumes:</u>

  • V = Vcon + Vcyl = 1/3πr²h₁ + πr²h₂
  • V = 1/3π*9²*12 + π*9²*120 = 31554.2 cm³

<u>Surface area of cone:</u>

  • A = A=πr(r+√(h₁²+r²)) = π*9(9 + √(9²+12²)) = 678.6 cm²

<u>Surface area of cylinder minus bases:</u>

  • A = 2πrh₂ = 2π*9*120 = 6785.8 cm²

<u>Total surface area:</u>

  • 678.6 + 6785.8 = 7464.4 cm²

-------------------------------------------------

B. Cube+ pyramid

<u>Volume:</u>

  • V = a³ + (1/3)a²h = a³ + (1/3)a²√(l²-(a/2)²)
  • V = 8³ + (1/3)8²√(10²-4²) = 707.5 cm³

<u>Surface area of pyramid:</u>

  • A = a² + 2al = 8² + 2*8*10 = 224 cm²

<u>Surface area of cube minus bases:</u>

  • A = 4a² = 4(8²) = 256 cm²

<u>Total surface area:</u>

  • A = 224 + 256 = 480 cm²

Nolan is deciding between two truck rental companies. Company A charges an initialfee of $90 for the rental plus $2 per mile dri
kotegsom [21]

first we writte the information they are giving to us:

For company A:

initial fee = $90

rent per mile = $2

For combany B:

initial fee = $50

rent per mile = $3

Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

\begin{gathered} A=90+2(n) \\ A=90+2(1) \\ A=90 \end{gathered}

And for company B:

\begin{gathered} B=50+3n \\ B=50+3(1) \\ B=53 \end{gathered}

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

\begin{gathered} A=B \\ 90+2n=50+3n \\  \end{gathered}

and finaly we can solve for n

\begin{gathered} 90-50=3n-2n \\ 40=n \end{gathered}

so if they drive for 40 miles the will pay the same
