Answer:
18/3
Step-by-step explanation:
6x3=18
For zeroes of r1,r2,r3, the factors of the function, f(x) are
(x-r1)(x-r2)(x-r3)
zeroes of -3,-5,2
(x-(-3))(x-(-5))(x-2)=
(x+3)(x+5)(x-2)
f(x)=(x+3)(x+5)(x-2)
expanded
f(x)=x³+6x²-x-30
Answer:
57
Step-by-step explanation:
10% of 570 = 57 (dividing by 10). Times that by 3, which is 171. Now divide 171 by 3, equals 57 (the answer).
Answer:
slope =
Step-by-step explanation:
1) Calculate the slope using slope formula,
. Use the two points given, substitute their x and y values into the formula, and solve.

Thus, the slope is
.
Maybe go about it this way:
40 divided by 5 equals 8
0.5 divided by 5 equals 0.1
Therefore, you add the two together to get the answer of 8.1
