Answer: C) The graph flips over the x axis.
This is because we're multiplying the y outputs by -1, to make them flip in sign from positive to negative (or vice versa).
Let's say the point (1,2) is on the f(x) curve. Multiplying y = f(x) by -1 will make the point turn into (1,-2). Apply this logic to every point on the f(x) curve and we end up with f(x) reflected over the horizontal x axis.
The notation we could write is either g(x) = -1*f(x) or g(x) = -f(x).

On a field trip, there are 3 chaperones for every 20 students. There are 92 people on the trip. Answer these questions. If you get stuck, consider using a tape diagram.
How many chaperones are there?
Answer:
14
Step-by-step explanation:
20 times four is 80 so we already have 12 chaperones because there are 3 chaperones for every 20 students.
20 divided by 3 is 6.6
We cannot have .6 of a chaperone so we round up to 7
And since 7 can only go into 20 two times
That means there are two more chaperones
2+12 is 14
There are 14 chaperones for the 92 students
(Hope this helps and hope im right)
Answer:
80(students)
12(chaperons)
Step-by-step explanation:
since total of 92 people in the trip including student and chaperon,add groups of 23 to become 92 or use this equation:
(20+3)×y=92
23y=92
y=92/23
y=4
therefore,
20×4=80(students)
3×4=12(chaperons)

411 miles from her aunt
39 miles from her cousins
Therefore the distance in which Lori lives to get grandmother than her aunt can be calculated as follows
= 411 miles - 272 miles.
= 139 miles
Find the gradients of lines A and B
Step-by-step explanation:
[tex]the \: gradient \: of \: line \: a \: is[/tex]
[tex]m = \frac{4}{1 } \\ m = 4[/tex]
[tex]the \: gradient \: of \: line \: b \: is[/tex]
[tex]m = \frac{ - 2}{1} \\ m = - 2[/tex]
Gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].
What is gradients?" Gradients is defined as the ratio of difference of y-coordinates to the difference of x-coordinates."
Formula used
Gradients [tex]= \frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]
According to the question,
Given from the graph,
Coordinates of Line A
[tex](x_{1} ,y_{1} ) = ( 3,3)\\\\(x_{2} ,y_{2} ) = ( 4,7)[/tex]
Substitute the value in the formula we get,
Gradient of line A [tex]= \frac{7-3}{4-3}[/tex]
[tex]= 4[/tex]
Coordinates of Line B
[tex](x_{1} ,y_{1} ) = ( -1,3)\\\\(x_{2} ,y_{2} ) = ( -2,5)[/tex]
Gradient of line B [tex]= \frac{5-3}{-2-(-1)}[/tex]
[tex]= -2[/tex]
Hence, gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].

In a box of chocolates, 1/5 of the chocolates contain nuts.
The rest of the chocolates do not contain nuts.
Write down the ratio of the number of chocolates that contain nuts to number of chocolates that do not contain nuts.
Give your answer in the form of 1:n
Answer:
The ratio of the number of chocolates that contain nuts to the number of chocolates = 1:4
Step-by-step explanation:
The parameters given are;
Proportion of the box of chocolates that contain nuts = 1/5
Proportion of the box of chocolates that do not contain nuts = 1 - 1/5 = 4/5
Therefore, we have in a box of chocolates with five chocolates;
The number of chocolates that contain nuts = 1
The number of chocolates that do not contain nuts = 4
Which gives the ratio of the number of chocolates that contain nuts to the number of chocolates as 1:4.

If $8000 is invested in an account for which interest is compounded continuously, find the amount of the investment at the end of 12 years for the following
interest rates.
(a) 2%
(b) 3%
(c) 4.5%
(d) 7%
Answer:
a) $1920, b) $2880, c) $4320, d) $6720
Step-by-step explanation:
a) Interest = Principal(Rate)(time)/100
Interest = $8000(12)(2)/100
Interest = $1,920
b) Interest = $8000(3)(12)/100
Interest = $2880
c) Interest = $8000(4.5)(12)/100
Interest = $4320
d) Interest = $8000(7)(12)/100
Interest = $6720

Kristen Lynn sells college textbooks on commission. She gets 4% on the first
$5000 of sales, 8% on the next $5000 of sales, and 12% on sales over
$10,000. In July of 1997 Kristen's sales total was $13,500.
Answer:
Step-by-step explanation:
5000 at 4% =200 (5000*0.04)
5000 at 8% = 400 (5000*0.08)
3,500 at 12% = 420 (3500*0.12)
200+400+420 = 1020
Her commission is 1,020 dollars :)

Match the lines m and n to the statements they represent
Answer:
Line n: A set of points where the coordinates of each point have a sum of 2
Line m: A set of points where the y-coordinate of each point is 10 less than the x-coordinate
Step-by-step explanation:
Given
Lines m and n (See attachment)
Required
Interpret both lines
First, we pick few coordinates of line m and then line n.
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex](x_3,y_3) = (2,-8)[/tex] -- At point D
For n
[tex](x_1,y_1) = (-2,4)[/tex] -- At point A
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex](x_3,y_3) = (12,-10)[/tex] -- At point C
Test for Statement A:
Set of point with a sum of 2
i.e.
[tex]x + y = 2[/tex]
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex]x_1 + y_1 = 13 + 3 = 16[/tex]
This statement is not true for line m
For n
[tex](x_1,y_1) = (-2,4)[/tex] -- At point A
[tex]x_1 + y_1 = -2 + 4 = 2[/tex]
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex]x_2 + y_2 = 6- 4 = 2[/tex]
[tex](x_3,y_3) = (12,-10)[/tex] -- At point C
[tex]x_3 + y_3 = 12- 10 = 2[/tex]
This statement is true for line n
Test for Statement 2:
Set of points where y is x - 10
i.e.
[tex]y = x - 10[/tex]
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex]y_1 = x_1 - 10[/tex]
[tex]3 = 13 - 10[/tex]
[tex]3 = 3[/tex]
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex]y_2 = x_2 - 10[/tex]
[tex]-4 = 6 - 10[/tex]
[tex]-4 = - 4[/tex]
[tex](x_3,y_3) = (2,-8)[/tex] -- At point D
[tex]y_3 = x_3 - 10[/tex]
[tex]-8 = 2 - 10[/tex]
[tex]-8 = -8[/tex]
This statement is true for line m
Solve the inequality 2.5d+11.4<-1.3d solve the inequality
Answer:
d < -3
Step-by-step explanation:
2.5d+11.4<-1.3d
3.8d+11.4<0
3.8d<-11.4
d < -3
Just isolate and solve for x and remember, what you do to one side, you must do to the other.
Hope this helps!
Answer:
[tex]d < -3[/tex]
Step-by-step explanation:
Move the constant to the right-hand side and change its sign:
[tex]2.5d < - 1.3d - 11.4[/tex]
Move the variable to the left-hand side and change its signs:
[tex]2.5d + 1.3d < 11.4[/tex]
Collect like terms:
[tex]3.8d < - 11.4[/tex]
Divide both sides of the inequality by 3.8:
[tex]3.8 \div - 11.4 = - 3[/tex]
Therefore, the answer is d < -3.

A souvenir store sells postcards and magnets.
Each postcard costs $1, and each magnet costs $3.
If Annalee purchased a total of 10 postcards and
magnets that cost a total of $22 before tax, how many
magnets did she purchase?
A) 3
B) 4
C) 5
D) 6
4
Answer:
6
Step-by-step explanation:
Answer:
D) 6
Step-by-step explanation:
Assumption method:
Assume all are postcards.
Total cost of postcards = 10 × $1
= $10
Difference between total = $22 - $10
= $12
Difference between subjects = $3 - $1
= $2
No. of magnets = $12 ÷ $2
= 6
