2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b
the slopt inercept form is y=-x-1
Answer:
0.000002
Step-by-step explanation:
since its -6+2 you need to move the decimal place in 2, 6 places foward. So the number would go from 2 to 0.000002.

Answer:
Year - (1993 - 1995)
Step-by-step explanation:
Rate of change in the number of toys sold =
In the interval (1990 - 1993),
Rate of change in number of toys sold =
=
= 4000
In the interval (1993 - 1995),
Rate of change =
=
= 5000
In the interval (2000 - 1995),
Rate of change =
=
= 3000
In the interval (2006 - 2000),
Rate of change =
=
= 1000
Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
