$(3)\ y = -x$

Step-by-step explanation:

Required

The equation in slope intercept form

Solving (3):

$m = -1$

$(x_1,y_1) =(4,-4)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -1(x - 4) -4$

Expand

$y = -x + 4 -4$

$y = -x$

Solving (5):

$m = -3$

$(x_1,y_1) = (1,-5)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -3(x - 1) - 5$

Expand

$y = -3x + 3 - 5$

$y = -3x -2$

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

Andrej [43]

Answer:

x = 348

Step-by-step explanation:

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

0.15x + 65 + 0.1x + 28 = 180

0.25x + 93 = 180

0.25x = 180 - 93

0.25x = 87

x = 87/0.25

x = 348
