Y=x2+3x+1 has how many real roots?
gregori [183]

Answer:

2

Step-by-step explanation:

we will find the discriminant of the equation

d = b^2  - 4ac (here, a = 1 , b = 3 , c = 1. from the general formula: ax^2 + bx + c)

d =  9 - 4

d = 5

since d > 0, the roots are real and different

hence, the both the roots of this equation are equal

The measures of the angles of triangle ABC are given by the expression and the table
n200080 [17]
In a triangle all the angles add up to 180  degrees.So we know that
(6x-1)+20+(x+14)= 180 
6x+x+14-1+20=180
    v        v
  7x +   13 + 20= 180
                 v
        7x + 33=180
               -33   -33
                  0     147
        7x/7    =   147/7
           x      =       21
x=21
Then you substitute:
(6x-1)       (x+14)
(6×21-1)    (21+14)
    v                  v
  126-1           35
125 degrees / 35 degrees
125+35+20=180

Find the midpoint of the segment joining the points (7,-4) and (9,4).
umka21 [38]
Jus take the average
so
the midpoint of
(x1,y1) and (x2,y2) is
((x1+x2)/2,(y1+y2)/2)
basically average the x and y terms


so
(7,-4) and (9,4)
average of 7 and 9 is 8
average of -4 and 4 is 0
(8,0) is the midpoint
