Answer:

y = -1/4x - 1

Step-by-step explanation:

The equation of a line is y = slope*x + y-intercept

Find the slope by picking two points shown on the graph and doing (y1-y2)/(x1-x2): (4, -2) & (-8, 1) = (-2-1)/(4-(-8) = -3/12 = -1/4 so the slope is 4.

Find the y-intercept by seeing where the line crosses the y-axis: y= -1

So therefore, y = -1/4x - 1

What is the m∠N ? Can someone help me :)

Sauron [17]

Answer:

Step-by-step explanation:

Use the sine law:

$\dfrac{MO}{\sin(\angle N)}=\dfrac{NM}{\sin(\angle O)}$

We have:

$MO=18\\\\NM=6\\\\m\angle O=17^o\to\sin17^o\approx0.2924$

Substitute:

$\dfrac{18}{\sin(\angle N)}=\dfrac{6}{0.2924}$ <em>cross multiply</em>

$6\sin(\angle N)=(18)(0.2924)$

$6\sin(\angle N)=5.2632$ <em>divide both sides by 6</em>

$\sin(\angle N)=0.8772\to m\angle N\approx61^o$

The formula to determine the asking price on a house is P=q+2n where q is the quality and n is the neighborhood. 1. Solve the eq

kotykmax [81]

1.q=p-2n
2.q=75000-2*20000
q=75000-40000
q=35000
3.p=90000+2*25000
p=90000+50000
p=140000

Hope this helps :)
