Find k if the slope of 4y= -kx - 2 is 4.

Mathematics
1 answer:
oee [108]3 years ago
8 0

Answer:

  • k = -16

Step-by-step explanation:

<u>Given formula:</u>

  • 4y= -kx - 2, where slope is 4

<u>Slope-intercept formula is:</u>

  • y = mx + b, where m is the slope

<u>Finding slope by bringing the formula to the same format as above:</u>

  • 4y = -kx - 2
  • y = -k/4x - 1/2

<u>Slope is -k/4 and comparing it with the given:</u>

  • -k/4 = 4
  • k = 4*(-4) = -16

Sahil chooses a number, divides it by 8 , adds 8 to the answer. Then multiples the answer with 8 . He obtains the result as 952
babunello [35]

Answer:

888

Step-by-step explanation:

Sahil chooses a number, [We'll call it x]

divides it by 8 ,   [x/8]

adds 8 to the answer.  [(x/8) + 8]

Then multiples the answer with 8 .  [((x/8) + 8)*8]

He obtains the result as 952 .   [((x/8) + 8)*8 = 952]

The number he chooses in the beginning was

((x/8) + 8)*8 = 952

x + 64 = 952

x = 888

CHECK:

Does (888/8 + 8)*8 = 952?

(119)*8 = 952?   YES

The number is 888

Does anyone know this answer I don’t get it
Svetradugi [14.3K]

Answer:

∠ XYZ ≈ 66.4°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosY = \frac{adjacent}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ Y = cos^{-1} (\frac{6}{15} ) ≈ 66.4° ( to 1 dec. place )

Convert the angle θ= 3π ​/5 radians to degrees. Express your answer exactly.<br><br>108
Olegator [25]

Answer:

216°

Step-by-step explanation:

Conversion from Radians to degrees : -

( θ * 360 ) / π

θ = 3π / 5

θ = ( 3π / 5 * 360 / π )

= ( 3 * 360 * π ) / ( 5 * π )

= ( 3 * 360 ) / 5

= 3 * 72

θ = 216°
