Hey there! :)
Answer:
4 - 40i
Step-by-step explanation:
Subtracting the two expressions:
(7 - 10i) - (3 + 30i)
Distribute the negative sign:
7 - 10i - 3 - 30i
Combine like terms:
4 - 40i
Answer:
+ 
=
+ 36 = 64
= 64-36
= 28
= 2
h = 5.29

Step-by-step explanation:
Answer:
The y-intercept is 3000. The slope is -275. Therefore, your equation in slope intercept form is y = -275x +3000.
Step-by-step explanation:
Y intercept is found where x = 0 or on the y axis, so the only place on this graph where x = 0 and there is a number on the y axis is at (0, 3000), making 3000 your y intercept. The slope is figured from two points, and taking y2-y1/x2-x1. This would give you 3000-2450/2-0 which is -550/2 which is -275. That's your slope. Slope intercept form is y = mx+b, where m is the slope and b is the y intercept. Just plug in, and you get y = -275x+3000
