Answer:

Step-by-step explanation:

you find slope (y1-y2)/(x1-x2) = (0-1)/(4-5) = -1/-1= 1

then you take a point (4,0)

y-0 = 1(x-4)

I hope this helps!

Answer:

y = x - 4

Step-by-step explanation:

The equation is just y = x shifted down 4 units, so it's y = x - 4. If you have to use all of the symbols, you can write "y = x * 1 - 4 + 0". Otherwise, use the one under "Answer" as it is shorter

BD bisects m m Find m

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

$m\angle ABC = 77.2^\circ$

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

$m\angle ABD=m\angle CBD$

Substituting the algebraic expressions for both angles:

$2.5x + 8.6=3.5x - 3.4$

Subtracting 8.6 and 3.5x:

$2.5x - 3.5x = -8.6 - 3.4$

Operating:

$-x = -12$

$x = 12$

The two angles are:

$m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ$

$m\angle CBD=3.5x - 3.4 = 38.6^\circ$

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

$m\angle ABC = 2*38.6^\circ=77.2^\circ$

$\mathbf{m\angle ABC = 77.2^\circ}$
