Answer:
a) parabola opens upwards
b) y-intercept y = 2
c) x₁ = 1 x₂ = 2
Step-by-step explanation:
y = x² - 3x + 2
This parabola is open upwards since the coefficient of x² is positive (1)
b) y-intercept is when x = 0 then
y = (0)² - 3*(0) + 2
y-intercept y = 2
to determine zeros, we can proceed as follows
x² - 3x + 2 = 0
Factoring that xpression
( x -1 ) * ( x - 2 ) = 0
Then either x- 1 = 0 and x₁ = 1 or
x - 2 = 0 and x₂ = 2
Answer:
{x,y} = {6,7}
Step-by-step explanation:
[1] 2x = 12
[1] x = 6
// Plug this in for variable x in equation [2]
[2] (6) - 5y = -29
[2] - 5y = -35
// Solve equation [2] for the variable y
[2] 5y = 35
[2] y = 7
// By now we know this much :
x = 6
y = 7
We are done

Answer:
80%
Step-by-step explanation:
75% + 20% - 15% = 80%
The probability is 80%
The increasing order of the complex numbers is (√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.
<h3>
Absolute values of the complex numbers</h3>
The absolute values of the complex numbers are determined as follows;
(sqrt3-sqrt3i)^4 = (√3 - √3i)⁴
(-1+sqrt3i)^12 = (-1 + √3i)¹²
(sqrt 3-i)^6 = (√3 - i)⁶
(sqrt2-sqrt2i)^8 = (√2 - √2i)⁸
(sqrt2-i)^6 = (√2 - i)⁶
Increasing order of the complex numbers;
(√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.
