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

Hope it is right
Answer:
n = -56
Step-by-step explanation:
first subtract the 24 from both sides. you get -14.
then multiply 4 to -14.
you get -56
Answer:
I'm not going to give you an exact answer because there could be many different ones
Step-by-step explanation:
The equations can be rewritten as:
2x - 7 = 7y
-4x + 19 = 3y
then you just insert a value for x and get the answer.
