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)

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

Help!! In the given figure, ∆ABC is congruent to ∆XYZ, find the value of "a".

crimeas [40]

Answer:

Step-by-step explanation:

Corresponding parts of congruent triangles are congruent.

So, XY = AB

3a - 3.9 = 1.7a - 1.3

3a = 1.7a - 1.3 + 3.9

3a = 1.7a + 2.6

3a -1.7a = 2.6

1.3a = 2.6

a = 2.6/1.3

a = 2

ΔABC ≅ ΔXYZ

First two letter

AB = XY

Second and third letters

BC = YZ

Third and first letter

CA = ZX
