Consider the graph showing two functions.
Which answer can be used to find the solution to the system of equations?
Answers
According to the graph, it is found that it represents the solution of the following system:
Option B [tex]x=\frac{9}{x}[/tex] is correct.
What are system of equations?A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.
The equations in the system can be linear or non-linear.
In the graph, two equations intersect at [tex]x = -3[/tex] and at [tex]x = 3.[/tex]
One is a straight line, in which the x-coordinate is equals to the y-coordinate, thus it is the line [tex]y = x.[/tex]
The other is an exponential equation, that goes to 0 as x goes to infinity, so x is in the denominator. At [tex]x = -3, y = -3,[/tex] and at [tex]x = 3, y = -3.[/tex] Thus, the function that has this graph is [tex]\frac{9}{x}[/tex], which means that the correct option is:
B [tex]x=\frac{9}{x}[/tex].

Kim saved $250 to buy new clothes for her summer vacation. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found a bathing suit for $35, two pairs of shoes for $15 each and five shirts with an average cost of $17 per shirt. She will have to pay 6% sales tax. If she buys all of the items, how much sales tax will she have to pay?
Answers
Answer:
She will have to pay $9 as sales tax
Step-by-step explanation:
Total amount with Kim = $250
Bathing suit = $35
Two pairs of shoes = 2 × $15
= $30
Five shirts = 5 × $17
= $85
Cost of items = Bathing suit + Two pairs of shoes + Five shirts
= $35 + $30 + $85
= $150
Sales tax = 6%
Amount of sales tax paid = 6% of $150
= 6/100 × 150
= 0.06 × 150
= $9
Kim will have to pay $9 as sales tax
Total cost of the items = cost of items + sales tax
= $150 + $9
= $159
Kim has enough money to buy all the items she likes

Make sure you include the name of the graph, the labels and the scale on x- and y-axes; Please use graphing paper, pencil and a ruler. Please help me it’s due today I would love the help.
Answers
You show the time on the x-axes (from 0 to 35) and the distance on the y-axes (from 0 to 10).
You start at origin of coordinates. Then the graph rises linear until it reaches the point (20|3.3333...), then it is parallel to the x-axes (as he does not move) until it reaches (25|3.3333...). Then it increases again until it reaches (35|10).
Basically, it's linear all the time, while the slope of the graph varies in three different intervals. (Actually it wouldn't be linear as he doesn't move with the same speed all the time but we can't go more into detail based on the information we have, so we use average values.)
You can use the rule of three to find out how far he moves.

Answers
An airplane travels 500 miles an hour then it will take 8 hours to travel 4.000 miles.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
An airplane travels 500 miles an hour. We need to find how long it will take to travel 4.000 miles.
We know that
Let t be the time taken by an airplane to travel 4000 miles.
An airplane traveled 500 miles = 1 hour
An airplane traveled in 1 mile = 1/ 500
An airplane traveled in 4000 miles = 4000/500
= 8 hour
Thus, It will take the airplane 8 hours to travel 4,000 miles.

Veronica bought 20 bags of candy for a school dance. The first 5 bags cost $1.79 each. The rest of the bags cost $1.19 each.
How much did Veronica spend on candy?
A. 8.95
B. 17.90
C. 26.80
D. 35.80
Answers
Answer:
Your answer is C. 26.8
Step-by-step explanation:
5 × 1.79 = 8.95
15 × 1.19 = 17.85
8.95 + 17.85 = 26.8
Answer: C ($26.80)
Step-by-step explanation:
This is a multiplication problem.
The first 5 bags of candy cost $1.79 each, so we multiply the cost by the amount of bags that we bought for that price:
5 * 1.79 = $8.95
The rest of the bags cost $1.19 each, so we need to multiply this number by some value. To find this value, we need to know how many bags we have left. We already bought 5, and we bought a total of 20, so we need to buy:
20 - 5 = 15 bags
Multiplying the cost for the rest of the bags (1.19) by the amount of bags we need to buy still (15), we get:
15 * 1.19 = $17.85
Now we know what the cost of the first 5 bags (8.95), and we know the cost of the 15 other bags (17.85). To find the total amount of money Veronica spent, we can just add these two values together.
8.95 + 17.85 = $26.80
This total cost is shown in answer C, so that is the answer.
