So, the rate per 7 minutes is 7:196

To find the unit rate (how many spins per minute) we need to divide the 196 by 7.

196/7 = 28

The unit rate is 1:28

At this rate, the unicycle makes 420 revolutions per 15 minutes. We find this by 28 * 15 = 420.

Solve by factoring : x^2-5x-36=0
il63 [147K]

Answer:

-9 and +4 are the factors

Step-by-step explanation:

-9 times +4 is -36 and if you add +4 to -9, you get -5.

After this your function will look like this:

x^2-9x+4x-36

and then:

x(x-9)+4(x-9)

so the answer is:

(x-9)(x+4)

  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)
  • Slope Formula: \displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (5, 9)

Point (-3, 9)

<u>Step 2: Identify</u>

x₁ = 5, y = 9

x₂ = -3. y = 9

<u>Step 3: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute in points [Slope Formula]:                                                              \displaystyle m=\frac{9-9}{-3-5}
  2. [Slope] [Fraction] Subtract:                                                                               \displaystyle m=\frac{0}{-8}
  3. [Slope] [Fraction] Divide:                                                                                  \displaystyle m=0
