1. Ilove ordering cookies from Tiff's Treats (not
sponsored, although I wouldn't object!). If Tiff's
Treats charges a delivery fee of $1 and costs $8.50
per half-dozen, which equation relates my cost, c,
and the number of half-dozens, h, I ordered?
a) C = 9.500h
b) C = 8.50h + 1
c) c = h + 8.50
d) h = 9.50c
e) None of these
c = cost
h = # of half-dozens ordered
c = $8.50h + $1 is the correct answer.

Find the difference quotient and simplify the answer. g(x) = 3x - 1
Answer:
Consider the difference quotient formula.
f(x+h)−f(x) / h
Find the components of the definition.
g(x+h)=3h+3x−1
g(x)=3x−1
Plug in the components.

Shellys old living room had a length that was twice its width. When she moved, her new living room was 2 feet longer and 4 feet wider that her old one. If w represents the width of her old living room write the expression used to represent the difference in the area of her old living room and her new living room.
Answer:
10w+6 is the difference between the two areas
Step-by-step explanation:
for the old room:
l=2w
wich mean
Area_old=l*w=2w*w=2w²
for the new room:
L=l+2 since l=2w => L=2w+2
W=w+4
so
Area_new=L*W=(w+4)*(2w+2)= 2w² +10w+6
the difference is :
Area_new - Area_old= 10w+6

During the summer, the height of the water in the pool decreased by 5 inches each week due to evaporation. What is the change in the height of the water over an 8 week period?
Answer:
40 inches
Step-by-step explanation:
We know that the height of water in a pool decreased 5 inches per week.
This means that we can form the equation [tex]y=-5x[/tex], since the amount of water remaining is proportionate to the amount of weeks that have passed.
We know [tex]x=8[/tex], since we need to find the change for 8 weeks.
[tex]y = -5\cdot 8[/tex]
[tex]-5 \cdot 8 = -40[/tex]
[tex]y=-40[/tex]
The change will be the absolute value of -40, which just makes it positive, so 40.
Hope this helped!
Answer:
40 inches evaporated
Step-by-step explanation:
5 in / week
Multiply 5 in by 8 wks
= 40 inches of water evaporated over 8 wks

Which graph shows a polynomial function of an odd degree?
Answer:
THE ANSWER IS C ON EDGE.
Step-by-step explanation:
If both sides of the graph are pointing in the same way, THE FUNCTION HAS AN EVEN DEGREE.
The degree of a polynomial is the highest power of the polynomial.
Graph 3 has an odd degree.
From the attachments, we have the following highlights
The first graph crosses the x-axis, 4 timesThe second graph crosses the x-axis, 6 timesThe third graph cross the x-axis, 3 timesThe fourth graph cross the x-axis, 2 timesThe above highlights mean that:
Graphs 1, 2 and 4 have even degrees, because they have an even number of x-interceptsGraphs 3 have an odd degree, because it has an odd number of x-interceptsHence, graph 3 has an odd degree.

The speed of a car traveling on a straight road increases from 63 m/s to 75
m/s in 4.2 seconds. What was the car's acceleration? m/s2 = meters per

Initial velocity = 63m/s
Final velocity = 75m/s

◈ Acceleration is defined as the rate of change of speed.
a = (v - u) / tIt is a vector quantity having both magnitude as well as direction.

19. The midpoint of JK is M(0, 1). One endpoint is /(-6, 3). Find the coordinates of
endpoint K. (Section 1.3)
Answer:
(6,-1)
Step-by-step explanation:
let coordinates of K be (x,y) then
[tex]0=\frac{-6+x}{2}\\or~-6+x=0\\x=6\\1=\frac{3+y}{2}\\y+3=2\\y=2-3=-1\\so ~K~is ~(6,-1)[/tex]
The coordinates of endpoint K will be (6,-1).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
Given that the midpoint of JK is M(0, 1). One endpoint is (-6, 3). The other end will be calculated as below:-
0 = ( -6 + x ) / 2
-6 + x = 0
x = 6
The value of the y coordinate will be calculated as below:-
y = 2 - 3 = -1
Therefore, the coordinates of endpoint K will be (6,-1).

(+4)

E
Answer:
m<DAE = 80°
Step-by-step explanation:
Given that m<CAB = 110°,
m<DAE = (x + 4)°,
m<EAF = 30°,
m<EAF + m<DAE = m<DAF (angle addition postulate)
30° + (x + 4)° = m<DAF (substitution)
(34 + x)° = m<DAF
<DAF and <CAB are vertically opposite angles. Vertically opposite angles are said to be congruent. Therefore:
m<DAF = m<CAB
(34 + x)° = 110° (substitution)
The equation above can be used to solve for x as follows:
34 + x = 110
x = 110 - 34 (Subtracting 34 from both sides)
x = 76
m<DAE = (x + 4)°
Plug in 76, to replace x
m<DAE = 76 + 4
m<DAE = 80°
