Answer:

82 units

Step-by-step explanation:

7 x 3 = 21

21 x 2 = 42

7 x 2 = 14

14 x 2 = 28

2 x 3 = 6

6 x 2 = 12

42 + 28 + 12 = 82

      Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

A) Let's solve for x. -3x-7y=-66

Step 1: Add 7y to both sides.

-3x - 7y + 7y = -66 + 7y \\-3x = 7y - 66

Step 2: Divide both sides by -3.

\frac{-3x }{-3} = \frac{7y - 66}{-3}

x = \frac{-7}{3}y + 22

Answer : \frac{-7}{3}y + 22

~~~~~~~~~~~~~

B) Let's solve for x. -10x-7y=-24

Step 1: Add 7y to both sides.

-10x - 7y + 7y = -24 + 7y \\-10x = 7y - 24

Step 2: Divide both sides by -10.

\frac{-10x}{-10} = \frac{7y - 24}{-10}

x = \frac{-7}{10}y + \frac{12}{5}

Answer : \frac{-7}{10}y + \frac{12}{5}

Find the angle that the line through the given pair of points makes with the positive direction of the x-axis
alexdok [17]

Answer:

Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.

Step-by-step explanation:

Given:

Let

A(x₁ , y₁) = (1 , 4) and  

B( x₂ , y₂ ) = (-1 , 2)

To Find:

θ = ?

Solution:

Slope of a line when two points are given is given bt

Slope(AB)=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }

Substituting the values we get

Slope(AB)=\dfrac{2-4}{-1-1}=\dfrac{-2}{-2}=1\\\\Slope=1

Also Slope of line when angle ' θ  ' is given as

Slope=\tan \theta

Substituting Slope = 1 we get

1=\tan \theta

\tan \theta=1\\\theta=\tan^{-1}(1)

We Know That for angle 45°,

tan 45 = 1

Therefore

\theta=45\°

Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.
