Answer:
<h2>9</h2>
Step-by-step explanation:
(-)(-) = (+)
(-)(+) = (-)
(+)(-) = (-)
(+)(+) = (+)
-(-21) = (-)(-21) = (+)21 = 21
-12 - (-21) = -12 + 21 <em>use commutative property: a + b = b + a</em>
= 21 + (-12) = 21 - 12 = 9

Answer:
maximum
Step-by-step explanation:
maximum/vertex is (5,3)
line of symmetry is 5
crosses y axis at (o,-72)
crosses x axis at (4,0) and (6,0)
this the is the equation if you simplify it
-3x^2+30x-72
Answer: $5000; $2000
Step-by-step explanation:
Simolw interest is calculated as: PRT/100
where,
P = principal
R = rate
T = time
Let the money in the 4-yr cd be represented by y.
Since rate = 5.2%
Simple interest = (y × 5.2 × 4)/100
Since he invested $3000 less in a 18-month CD, Let the money in the 18-month CD be represented by (y - $3000).
Then, S.I = [(y - $3000) × 3 × 1.5]/100
The total interest = $1130
We then equate the two simple interest together. This will be:
= (y × 5.2 × 4)/100 + (y - $3000) × 3 × 1.5]/100 = $1130
0.208y + 0.045(y - $3000) = $1130
0.208y + 0.045y - $135 = $1130
0.253y = $1130 + $135
0.253y = $1265
y = $1265/0.253
y = $5000
The money invested in 4-yr CD = $5000
The money invested in the 18-month CD = $5000 - $3000 = $2000
