$18.11
$13.39
$17.25
$18.53
Divide sale price by (1 - percent of discount):
15.75 / (1- 0.15) =
15.75 / 0.85 = 18.53
Answer = $18.53
Answer:
18.53
Step-by-step explanation:
18.53*0.15≈2.7795
Rounded = 2.78

Of those who like to fish, what percent are ages 13-18?
Answer:
B.) 42.9
Step-by-step explanation:
The percent that we are trying to find out is 12/28
I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)
Anyways 12 divided by 28 = 42.857etc.
If we simplify this then that gives us our answer of B.) 42.9

The graph of the rational function f is shown. Which graph is the graph of g(x)=-f(x)?
Using translation concepts, it is found that graph A is equivalent to the graph of g(x)=-f(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The transformation g(x)=-f(x) is a reflection over the x-axis of function f(x), which is given by graph A.

Sumaya is using two different strings of Christmas lights to decorate her house.one string flashes every 10 seconds.the other one string flashes every 15 seconds.when Sumaya turns on the lights they flashes at the same time.work out how long it will be before they flash again at the same time.use the LCM to help you work out your answer
Answer: 30 seconds
Step-by-step explanation:
From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.
The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:
10 = 10, 20, 30, 40, 50 ...
15 = 15, 30, 45, 60, 75 ....
We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.
They'll both flash again at same time in 30 seconds.
Write a System of Equations to solve the following problem:
The school that Maria goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 12 student tickets for a total of $51. The school took in $93 on the second day by selling 5 senior citizen tickets and 6 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Cost of Senior Citizen Ticket: $
Cost of Student Ticket: $
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
Step-by-step explanation:
Let the price of a senior citizen ticket be s.
Let the price of a student ticket be t.
Day 1:
s + 12t = 51
Day 2:
5s + 6t = 93
The system of equations is:
s + 12t = 51
5s + 6t = 93
Let's use the substitution method to solve it. Solve the first equation for s.
s = 51 - 12t
Now substitute s in the second equation with 51 - 12t.
5s + 6t = 93
5(51 - 12t) + 6t = 93
255 - 60t + 6t = 93
Subtract 255 from both sides. Combine -60t and 6t.
-54t = -162
Divide both sides by -54.
t = 3
Now substitute 3 for t in the equation
s = 51 - 12t
s = 51 - 12(3)
s = 51 - 36
s = 15
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
How does the graph of g(x)=1/x-5. +2 compare to the graph of the parent function f(x)=1/x
Answer:
x value of vertical asymptote and y value of horizontal asymptote
Step-by-step explanation:
The graph of 1/x approaches infinity as x approaches 0 (the vertical asymptote)
As x gets either bigger or smaller, 1/x approaches the x-axis (from above on the positive side, from below on the negative side) (the horizontal asymptote)
Consider 1/(x-5) + 2, at what value of x does the graph 'go nuts' ?
When the bottom of the fraction becomes 0, x - 5 becomes 0 when x = 5, so the vertical asymptote of g(x) is at x=5
What value of y does f(x) approach as x gets more positive or more negative - as x gets bigger (as an example), y approaches 0
What y value does g(x) approach as x gets bigger? Well, as x gets big, 1/(x-5) gets small, approaching 0. The smallest 0 + 2 can get is 2, so y=2 is the horizontal asymptote
