Answer:
−1 + i times the square root of 3
is the answer.
Step-by-step explanation:
Given is a quadratic equation in x
using completion of squares method
Equate to 0
Take square root
Subtract one from both sides
x = [/tex]-1±i\sqrt{3}[/tex]
The last option namely
−1 + i times the square root of 3 only matches with our answre
Hence last option is right.
Answer:
x=3, y =2
(3,2)
Step-by-step explanation:
y =2/3 x
y = -2/3 x +4
set them equal to each other y=y
2/3 x = -2/3 x + 4
add 2/3 x to each side
2/3 x+2/3x = -2/3x + 2/3 x + 4
4/3 x = 4
multiply by 3/4 on each side to clear the fraction
3/4 * 4/3 x = 3/4 * 4
x = 3
now we need to find y
y = 2/3 x
y = 2/3 * 3
y =2
When two variables have an inverse relationship, the slope is negatively correlated.
