Whats an equation that the passes through (-6,4) and is parallel to y=1/2x+8

1 answer:

6 0

Formula y-y1= m(X-X1)
Since its parallel the m is 1/2
The -6 is X1 and the 4 is y1
Okay now do formula

Y-4= 1/2(X--6)
Y-4= 1/2X+3
Add 4

Y= 1/2x +7

Find the mean absolute deviation for each set of data:

aivan3 [116]

Answer:

1) 1.8

2) 1.7

Step-by-step explanation:

(for part A)

Mean: 3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6 = 53/15 = 3.5

3.5 - 3 = 0.5

3.5 - 5 = 1.5

3.5 - 6 = 2.5

3.5 - 3 = 0.5

3.5 - 2 = 1.5

3.5 - 1 = 2.5

3.5 - 0 = 3.5

3.5 - 4 = 0.5

3.5 - 7 = 3.5

3.5 - 4 = 0.5

3.5 - 5 = 1.5

3.5 - 6 = 2.5

mean absolute deviation: 0.5 + 1.5 + 2.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 0.5 + 3.5 + 0.5 + 1.5 + 1.5 + 2.5 = 27.5/15 = 1.8

(part B)

Mean: -3 + -2 + -1 + 0 + 1 + 2 + 3 = 0/7 = 0

0 - (-3) = 3

0 - (-2) = 2

0 - (-1) = 1

0 - 0 = 0

0 - 1 = 1

0 - 2 = 2

0 - 3 = 3

mean absolute deviation: 3 + 2 + 1 + 0 + 1 + 2 + 3 = 12/7 = 1.7

Regan cycles 78 miles in 6 hours.

Brut [27]

Answer:

12 mph

Step-by-step explanation:

First 30 miles while cycling at 15 mph. This means he spent 2 hours here.

Thus the 4 hours on the last 48 miles.

Average speed = distance / time

Average speed = 48 miles / 4 hours

Average speed = 12 mph

Therefore Regan's average speed is 12 mph for the last 48 miles.

Identify the values of variables x, y, and z based on the image given of the angles formed by a transversal and parallel lines

Paul [167]

Answer:

$x=62\\y=94\\z=94$

Step-by-step explanation:

Let's start by identifying relevant angle theorems for two parallel lines cut by a transversal.

Alternate Interior Angles Theorem

Two angles that are on different sides of the transversal and inside of the two parallel lines are congruent (=).

Alternate Exterior Angles Theorem

Two angles that are on different sides of the transversal and outside of the two parallel lines are congruent (=).

Same-side Interior Angles Theorem

Two angles that are on the same side of the transversal and inside of the two parallel lines are supplementary (= 180).

Same-side Exterior Angles Theorem

Two angles that are on the same side of the transversal and outside of the two parallel lines are supplementary (=180).

Corresponding Angles Theorem

Two angles on a figure that correspond are congruent (=).

Now, let's look at the figure and apply these theorems.

$z$ and $86$ are same-side exterior angles, meaning they're supplementary:

$z+86=180$

Subtract $86$ from both sides of the equation:

$z=94$

Now that we know our $z$ value, let's recognize that $z$ ( $94$ )corresponds to $x+32$ , meaning they're congruent:

$x+32=94$

Subtract $32$ from both sides of the equation:

$x=62$

Let's find the value of the angle:

$(62)+32$

Add:

$94$

Since the corresponding angles are of the same value, they're congruent, proving our $x$ & $z$ values correct.

Since $y$ and the angle represented by the expression $x+32$ ( $94$ °) are alternate-interior angles, they are congruent:

$y=94$
