Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.

if
we have 2 distinct real solution
if
we have no real solution but 2 complex solutions
if
we have 2 identical real solution
Answer:
c
the total number of marbles are 12 and there are 3 colours so you divide 12 by 3
Answer:
the y intercept is 4
and frm that point to another spot on the line you go DOWN one unit (negative)
and two units to positive (to the right) thus the slope is - 1 (down) and 2 positive to the right
-1/2 = slope
y = -1/2 + 4
Step-by-step explanation:
((X1+x2)/2,(y1+y2)/2)
---> ((2+2)/2,(1+4)/2)
---> (2,2.5)
Answer:
Slope is 2.
Step-by-step explanation:
y=mx+b, m= slope.
y-7=2x-20
y=2x-27
