Answer:
12.5
Step-by-step explanation:
f of x just means y, so you're just finding y when x = 1/2
X^2+2x+3+2(x^2+2x+3)+3+4(x^2+2x+3)+6+8(x^2+2x+3)+9+16(<span>x^2+2x+3)+12
add that up and you will get your answer and you get </span><span>31x²+62x+123</span>
Answer:
y -8 = -5(x -6)
Step-by-step explanation:
The point-slope form of the equation for a line is generally written ...
y -k = m(x -h)
for slope m and point (h, k).
The slope of your parallel line is the same as the slope of the reference line, -5. So your equation is ...
y -8 = -5(x -6)
B) Minimum= 1
Q1= 3
Q3= 8
Lower Fence= Q1-(IQR*1.5)
= 3-(5*1.5)
= -4.5
Maximum= 11
Median= 7
IQR= 8= 3= 5
Upper Fence= Q3+(IQR*1.5)
= 8+(5*1.5)
= 15.5
c) No. All values are between the lower fence and the upper fence.
Answer:
The cost of one hot dog is $1.5 and the cost of one drink is $2.
Step-by-step explanation:
Let
<em>h</em> = the cost of a hog dog and <em>d</em><em> </em>= the cost of a drink
We know from the information given that:
- Carl bought 5 hot dogs and 3 drinks and paid $13.50. This is equal to
- Susan purchased 2 hot dogs and 3 drinks and was charged $9.00. This is equal to
So we have a system of equations
We can solve by elimination as follows:
Subtract from
Therefore
<em>h</em> = $1.5 and <em>d</em><em> </em>= $2
