Answer:

y = - \frac{5}{2} x + 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - \frac{5}{2} , then

y = - \frac{5}{2} x + c ← is the partial equation

To find c substitute (8, - 9) into the partial equation

- 9 = - 20 + c ⇒ c = - 9 + 20 = 11

y = - \frac{5}{2} x + 11 ← equation of line

How do i solve this?
shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

8^{2} + y^{2}  = (8\sqrt{6} )^{2} \\      y^{2}        = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y  = \sqrt{320}

∴ y = 8\sqrt{5}

Hope that helps!!

Solve the following automotive-services problems based on the examples shown previously. Voltage = 12 v Current = 48 amps Resist
yawa3891 [41]
For this case the first thing you should know is that we have the following definition:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 Therefore, by clearing the Resistance we have:
 R = V / I
 Substituting the values:
 R = 12/48
 R = 1/4 ohms
 Answer:
 The value of the resistance is: 
 R = 1/4 ohms

The Broad Street subway line express train stops at city hall every 9 minutes. The local train stops at the station every 12 min
Dmitry_Shevchenko [17]

Both the train will meet after 36 minutes.

<h3>Concept:</h3>
  • To find when both the train will meet again at the same time, we need to find the LCM of the frequency.

<h3>How to solve the given question?</h3>
  • Frequency of express train = 9 minutes = 3 × 3
  • Frequency of local train = 12 minutes = 2 × 2 × 3
  • LCM = 2 × 2 × 3 × 3 = 36

Thus, both the train will meet after 36 minutes.
