Answer:
for 1 I am guessing D and for 2 I am guessing B.
Answer:
Well you expect 400 customers and in every fifith customers you give them a free turkey so you have to divide that then divide figure out how many times you'll give away a coupon so you also divide 400 with 3
Answer:
The zeroes are -6, 1/2 and 2.
Step-by-step explanation:
f(x) = 2x3 + 7x2 - 28x + 12 = 0
From the first and last coefficient 2 and 12, one guess for a zero is x = 2.
So substituting x = 2:
f(2) = 16+ 28 - 56 + 12 = 0
So x = 2 is a zero and x - 2 is a factor of f(x)
Performing long division:
x - 2)2x3 + 7x2 - 28x + 12( 2x2 + 11x - 6 <------- Quotient
2x3 - 4x2
11x2 - 28x
11x2 - 22x
- 6x + 12
-6x + 12
.............
Now we solve
2x2 + 11x - 6 = 0
(2x - 1)(x + 6) = 0
2x - 1 = 0 or x + 6 = 0, so:
x = 1/2, x = -6.
Y + 5x = 6
y + 5(-1) = 6
y + (-5) = 6
y - 5 = 6
y - 5 (+5) = 6 (+5)
y = 11
when x = - 1, y = 11
y + 5(0) = 6
y + 0 = 6
y + 0 (-0) = 6 (-0)
y = 6
when x = 0, y = 6
y + 5(1) = 6
y + 5 = 6
y + 5 (-5) = 6 (-5)
y = 1
when x = 1, y = 1
hope this helps
The rate of change of function 1 (a horizontal line) is zero.
The rate of change (slope) of function 2 is the x-coefficient, 8.
8 is 8 more than 0.
The 4th selection is appropriat:
8
