Answer:

y = ⅔x - 5

Step-by-step explanation:

To write the equation, find the slope (m), to enable you write the equation of the line in point-slope form given a point, (-3, -7) that the line passes through.

Since the line is parallel to 2x - 3y = 24,, it would have the same slope (m) value.

Rewrite 2x - 3y = 24 in slope-intercept form.

Thus:

2x - 3y = 24

-3y = -2x + 24

y = ⅔x - 12

The slope of 2x - 3y = 24 is ⅔. Therefore, the line that is parallel to 2x - 3y = 24 is also ⅔.

To write the equation of the line, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)

Thus:

y - (-7) = ⅔(x - (-3))

y + 7 = ⅔(x + 3)

y + 7 = ⅔x + 2

y = ⅔x + 2 - 7

y = ⅔x - 5

Hw 17 arcs and chords
madreJ [45]

Answer:

1. 105°

2. 85°

3. 80°

4. 148°

5. 116°

6. 82°

7. 135°

8. x = 7

9. x = 2

10. x = 1

11. x = 10

Step-by-step explanation:

1. Arc WZ = Arc XY

Arc WZ = 105° Therefore Arc XY = 105°

2. Arc SR = Arc TU

Arc SR = 85° Therefore Arc TU = 85°

3. Arc PQ = Arc QR

Arc PQR = 40° + 40°

Arc PQR = 80°

4. Arc RT = 64°

x = (360° - 64°)/2

x = 296°/2

x = 148°

5. x = 116°

If the chords are congruent to each other, then the arcs are also congruent to each other.

6. x = 82°

If the chords are congruent to each other, then the arcs are also congruent to each other.

7. Arc BC = 90°

x = (360° - 90°)/2

x = 270°/2

x = 135°

8. 2x + 4 = 18

2x = 18 - 4

\dfrac{2x}{2}=\dfrac{14}{2}

x = 7

9. 2x + 1 = 5x - 5

2x - 5x = -5 - 1

\dfrac{-3x}{-3} = \dfrac{-6}{-6}

x = 2

10. 3x + 16 = 12x + 7

3x - 12x = 7 - 16

\dfrac{-9x}{-9}=\dfrac{-9}{-9}

x = 1

11.  3x - 11 = x + 9

3x - x = 9 + 11

\dfrac{2x}{2}=\dfrac{20}{2}

x = 10
