Answer:

Read on:

Step-by-step explanation:

Step 1:

  System #1

y=\frac{1}{2}x-2

y=-3x+5

  System #2

y=4x-3

y=4x-3

  System #3

y=\frac{-2}{3}x-1

y=\frac{-2}{3}x+2

Step 2:

  Look at First Drawing:

  Look at Second Drawing

  Look at Third Drawing

Step 3: Intersecting

Step 4: Overlap (Same Line)

Step 5: Parallel

Step 6:

  Intersecting: If the slopes are unequal

  Parallel: If the slopes are equal but the y-intercept is unequal

  Same line: If the slopes and y-intercepts are all equal

Step 7: The lines are parallel because although the slopes are equal, the y-intercepts are not

If each data is increased by a constant K then find it's mean ?? answer fast pleaseeeeeeeeeee​
MArishka [77]

Answer:

The mean is also increased by the constant k.

Step-by-step explanation:

Suppose that we have the set of N elements

{x₁, x₂, x₃, ..., xₙ}

The mean of this set is:

M = (x₁ + x₂ + x₃ + ... + xₙ)/N

Now if we increase each element of our set by a constant K, then our new set is:

{ (x₁ + k), (x₂ + k), ..., (xₙ + k)}

The mean of this set is:

M' = ( (x₁ + k) + (x₂ + k) + ... + (xₙ + k))/N

M' = (x₁ + x₂ + ... + xₙ + N*k)/N

We can rewrite this as:

M' = (x₁ + x₂ + ... + xₙ)/N + (k*N)/N

and  (x₁ + x₂ + ... + xₙ)/N was the original mean, then:

M' = M + (k*N)/N

M' = M + k

Then if we increase all the elements by a constant k, the mean is also increased by the same constant k.

Algebra 1 solve − 0.32 + 0.18 = 0.25 − 1.95
disa [49]

Answer:

Step-by-step explanation:

Add 0.32 and 0.18 to get 0.5.

0.5=0.25 - 1.95

subtract 1.95 from 0.25 to get —1.7.

0.5=—1.7

compare 0.5 and —1.7.

Vinil7 [7]

Answer:

Value of x = 19.42 unit (Approx)

Step-by-step explanation:

Given:

Base = 6 unit

Angle θ = 72°

Find:

Value of x

Computation:

Cos θ = base / Hypotenuse

Cos 72° = 6 / x

0.3090 = 6 / x

x = 19.4174

Value of x = 19.42 unit (Approx)
