A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2,

Oksanka [162]

Answer:

A. one B. (3, 4)

Step-by-step explanation:

1. A good graph can answer both parts (see attached image).

2. Write equations for the two lines and find a simultaneous solution.

Line A: Slope from (2, 6) to (5, 0) is $m=\frac{6-0}{2-5}=\frac{6}{-3}=-2$

Using point-slope form $y-y_1=m(x-x_1)$

$y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10$

Line B: Slopt from (6, 6) to (0, 2) is $m=\frac{6-2}{6-0}=\frac{2}{3}$

Using point-slope form, the equation for Line B is

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

To find the simultaneous solution, set the y's equal.

$-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3$

Find y using either equation to get y = 4.

What improper fraction is the same as 12 3/4? A) 51/4 B) 12/4 C) 123/4 D) 48/4

lbvjy [14]

51/4 because you multiply 12*4 which is 48 and add 3 so you get 51. You keep the denominator so you should get 51/4.

Please help! I'm confused...

maw [93]

So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
