SIZIF [17.4K]

Answer:

The answer is "y= -x+7"

Step-by-step explanation:

If \bold{\theta = 135^{\circ}}

point: p=(2,5)

Formula:

\to m= \tan \theta \\\\\to (y-y_1)= m(x-x_1)

\to m= \tan \ 135^{\circ} =  -1\\\\\to x_1= 2\\\\\to y_1=5

Put the value in the above formula:

\to y- 5 = -1(x-2)\\\\\to y- 5 = -x+2\\\\\to x+y = 5+2\\\\\to x+y=7

\to y= -x+7

USPshnik [31]

Answer:

Step-by-step explanation:

1) y = 50x + 2500

2) y = 200x + 1000

if we build a system with the two equations, we have:

50x+2500 = 200x + 1000

150x = 1500

x = 10

y = 2000 + 1000 = 3000

3) 10

4) $3000
