The c and y intercept
frosja888 [35]

y + 5 = 2(x + 1)

y - intercept \: (x = 0) \\ y + 5 = 2(0 + 1) \\ y + 5 = 2 \\ y =  - 3

<h2>Y intercept: ( 0 , -3 )</h2>

x - intercept \: (y = 0) \\ 0 + 5 = 2(x + 1) \\ 5 = 2x + 2 \\ 2x = 3 \\ x =  \frac{3}{2}

So for this answer I got 5 hrs. &gt; 38.13 - 12 = 26.13/4.75 = 5 (rounded). However, my answer is wrong. Not sure how else I can
Archy [21]

9514 1404 393

Answer:

  38.13 = 12 +4.75h

  5.5 hours

Step-by-step explanation:

(a) The charge (c) for renting a bike for h hours is ...

  c = helmet charge + hourly charge × hours

  c = 12.00 +4.75h

To find the number of hours when the charge is 38.13, we would use the equation ...

  38.13 = 12.00 +4.75h

__

(b) To solve this 2-step linear equation, we first subtract the constant

  26.13 = 4.75h

then we divide by the coefficient of the variable.

  26.13/4.75 = h ≈ 5.5

Amanda rented the bike for 5.5 hours.

_____

<em>Additional comment</em>

The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.

The area of a square can be found by squaring one side.

Let's set the side as x feet.

x^2=225
x=square root of 225
x=15

The length of each side is 15 feet.

Hope this helps!
