Find BD 2x - 9 11 - D B С X + 9

Gnesinka [82]

Answer:

Step-by-step explanation:

AB + BC = AC and AC = 14

x + 15 + 2x + 32 = 14 add like terms

3x + 47 = 14 subtract 47 from both sides

3x = -33 divide both sides by 3

x = -11 now the length of BC

2x + 32 replace x with -11

2*(-11) + 32 = 10

PLEASE HELP I DO NOT UNDERSTAND AT ALL AND SHOW YOUR WORK !!

Agata [3.3K]

Answer:

y intercept (-6,0), x-intercept (0,-8) : $y = \frac{-4}{3}x -8$

y intercept (0,-6), x-intercept (-2,0): $y = -3x -6$

y intercept (0,8), x-intercept (1.6,0): $y = -5x + 8$

y intercept (0,7), x-intercept (-1.4,0): $y = 5x + 7$

Step-by-step explanation:

y = mx + b

*note: b is the y intercept

1. y intercept (-6,0), x-intercept (0,-8)

$m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6} = \frac{-4}{3}\\y = \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8$

2.y intercept (0,-6), x-intercept (-2,0)

$m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2} = -3\\y = -3x + b \\y = -3x -6$

3. y intercept (0,8), x-intercept (1.6,0)

$m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8$

4. y intercept (0,7), x-intercept (-1.4,0)

$m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7$
