Answer:
I'd really love to help you but the way you asked made you sound so needy and that just made me not want to answer sorry...
Step-by-step explanation:
First you can change 3 to 10/10 so that they can have the same denominator. Now, since you do that the number is now 2.
Now, do 10/10-1/10=9/10.
After do 2-4=-2.
So, your final answer is -2 9/10.
Y = 18 x² + m x + 2
Exactly one x - intercept is for:
D = m² - 4 · 18 · 2 = 0
m² - 144 = 0
m² = 144
Answer:
m = -12 or m = 12
Answer:
(1, 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
C(1, - 2 ) → C'(1, 2 )
