Answer:
Slope - intercept form:
B) y= x -4
Step-by-step explanation:
(3,-1) and (-1,-5)
Slope = (-5 + 1)/(-1 - 3)
Slope = -4 / -4
Slope = 1
Point slope form:
y + 1 = 1 (x - 3)
y +1 = x - 3
y = x - 4 <------------------slope - intercept form
450,500 because 120,000 and 330,000 and 500 thats the answer
Answer:
63*
Step-by-step explanation:
The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.
The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.
Therefore, 63 is the correct answer.
