Question

Find the coordinates of the vertices of the figure formed by:
y> 1/4x + 3/4
y> -x + 7
y< 2/3x + 2



Select one:


a. (–4, 0), (5, 4), (5, 2)

b. (–3, 0), (5, 4 ), (5, 2)

c. (–4, 0), (3, 4), (5, 2)

d. (–3, 0), (3, 4), (5, 2)

Answer 1

@FutureMathProfessor please help

Answer 3

Use = instead of "<" and ">" Then you can solve those equations in terms of y. Then set the equations equal to each other, (Equation 1 = equation 2, equation 2 = equation 3, equation 1 = equation 3). By doing this, you will find the intersection points.

Answer 4

Which in turn are the vertices.

Answer 5

thanks

Answer 6

No problem.

Answer 7

So, what is the answer?

Answer 8

I think it is b

Answer 9

Am I right

Answer 10

\[1)\ \ \frac{1}{4}x + \frac{3}{4} = -x + 7 \rightarrow x = 5,\ y=2\ \ ||\ (5,2)\]
\[2)\ \ -x + 7 =\frac{2}{3}x + 2 \rightarrow x =3,\ y=4\ ||\ (3,4)\]
\[3)\ \ \frac{1}{4}x + \frac{3}{4} = \frac{2}{3}x + 2 \rightarrow x = -3,\ \ y=0\ \ ||\ (-3,0)\]
Answer is d)
