First you to eliminate i from denominator.
mult by (7+3i) above and below
=(49+42i-9)/(49-9)
which is (40+42i)/40 which can simplify
To find slope, pick any 2 points and use formula: (y2-y1)/(x2-x1)
2 points on line: (4,0), (0,-2)
(-2-0)/(0-4) = -2/-4 = 1/2
a) the slope is 1/2
Y = 1/2x + b
0 = 1/2(4) + b
0 = 2 + b, b = -2
b) -2 is the y intercept
Put the equation together
c) y = 1/2x - 2

Step-by-step explanation:
A random guy made 100 bird houses and each bird house has 100 seeds how many seeds are there in total 100,000
Answer:
1.715 kg
Step-by-step explanation:
343 m/s * 5 seconds = 1715 meters per second
Convert from m/s to kg by dividing by 1000
1715 meters per second / 1000 kilograms = 1.715 kg
X^2-18x__=-34
X^2-18x+(18/2)^2=-34
X^2-18x+81=-34+81
(X+9)^2=47
(X+9)^2-47=0
