Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar.
ab and bc form a right angle at their point of intersection, b.
if the coordinates of a and bare (14, -1) and (2, 1), respectively, the y-intercept of ab is
and the equation of bc
is y =
x+
if the y-coordinate of point c is 13, its x-coordinate is

y-intercept of AB is 4/3.

The equation of line BC is y=6x-11.

The x-coordinate of point C is 4.

Step-by-step explanation:

Given information: AB⊥BC, A(14,-1) and B(2,1).

If a line passes through two points then the equation of line is

where, m is slope.

Slope of line AB is

The equation of line AB is

The equation of line AB is .

Substitute x=0 to find the y-intercept of AB.

Therefore y-intercept of AB is 4/3.

Line AB and BC are perpendicular, so product of their slopes is -1.

Slope of BC is 6 and it passes through (2,1). So equation of BC is

Therefore the equation of line BC is y=6x-11.

Point C lies on line BC. The y-coordinate of C is 13.

Substitute y=13 in the above equation.

Add 11 both sides.

Divide both sides by 6.

Therefore the x-coordinate of point C is 4.

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
