Answer:
discriminant =0
1 real root
Step-by-step explanation:
The discriminant is b^2 -4ac
when the equation is written in the form ax^2 +bx+c
f(x) = 3x^2 +24x+48
a = 3 b = 24 and c =48
discriminant = 24^2 - 4(3)*(48)
=576-576
=0
If the discriminant >0 we have 2 real roots
if discriminant = 0 we have 1 real root
if discriminant <0 we have 2 complex roots
point slope form
y-y1 = m(x-x1)
y-5 = -2/15(x--5)
y-5 = -2/15 (x+5)
change to slope intercept form
distribute
y-5 =-2/15x -10/15
y-5 = -2/15x -2/3
add 5 to each side
y = -2/15x -2/3 + 5
y = -2/15x -2/3 + 15/3
y = -2/15x +13/3
Step-by-step explanation:
how i think this question is
13+ -y
y=6
= 13 + -6
=7
therefore the answer is 7
