Answer:
2 is neither because they don't make a 90 degree angle and 3 is supplementary because they make a 180 degree angle.
1. using the quadratic formula you get -9+/-sqrt(9^2-4*(1*2))/2*1
this simplies to x = -9 +/- sqrt(73)/2
x = -0.22799812 and -8.77200187
2. complex numbers have the letter i with them
using the quadratic formula
you get 0 +/- sqrt(0^2-4*(1*24))/2*1
x = -2i sqrt(6) and 2i sqrt(6)
Answer:
y=5x+2
Step-by-step explanation:
First, let's put this into y=mx+b form.
m is the growth, or how much y increases when x increases by 1
b is the initial condition, or the value of y when x equals 0.
So, y=(5)x+2 because y increases by 5 when x increases by 1. and 2 because that is the value of y when x is 0.
Hope that helped.
Answer: 1.78 and -1.78
Step-by-step explanation:
1. You have the following equation given in the problem above:
2. To solve it you must:
- Subtract 1 from both side of the equation:
- Divide both sides of the equation by 6, then:
- Apply the square root at both sides of the equation:
Then, the solution is:
