two functions are given below how does the graph of p compare with the graph of q
Answer:
The answer should be choice B.
Step-by-step explanation:
By using the process of elimination, you can cross out choices A and D.
According to the equation, the slope is of p(x) is smaller than q(x), thus q(x) will be steeper than q(x).
The valid answer is B because choice C is wrong.
How do I do this? It's about systems of equations.
Answer:
D.

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder on food. How much has he left.
Answer:
Amount left = 2040
Step-by-step explanation:
Given that:
Per year salary = 12,000
Amount spent on transport = 10%
Transport = [tex]\frac{10}{100}*12000[/tex] = 0.1 * 12000
Transport = 1200
Tax = 5%
Tax = 0.05 * 12000
Tax = 600
Total = 1200 + 600 = 1800
Amount left = 12000 - 1800 = 10200
Food = 80% of remainder
Food = 0.8 * 10200
Food = 8160
Amount left after food = 10200 - 8160 = 2040
Hence,
Amount left = 2040
rearrage the equation from standard to y = mx+b from
y - 4x = 6
Answer: y = 4x + 6
Step-by-step explanation:
Isolate y on the left by adding 4x to both sides of the equation.
In slope intercept form , now you have the slope, m = 4
And the y-intercept, b = 6
On a certain hot summer's day, 386 people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $807.50. How many children and how many adults swam at the public pool that day?
Answer:
Call x is childrens
Call y is adults
x + y = 386 (1)
1,75x + 2,5y = 807,5 (2)
(1) => x = 386 - y => (2) 1,75 ( 386-y )+2,5y = 807,5
0,75y=132 => y = 176 and x = 210

Answer:
minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by t^1=2.1 minutes.
Then they are able to reduce that time by t^2=1/10
If their final time is 3.96 minutes, then
X - t^1 - t^2 = 3.96
=> X = 3.96 + t^1 + t^2
=> X = 3.96 + 2.1 + 1/10
=> X = 6.16

HELPPP PLEASE!!Three friends went shopping. They each bought one pair of shoes that
cost $20 and 4 shirts that cost x dollars.
1. Write an expression that represents this situation.
2. Simplify the expression.
Answer:
1. [tex]3 (20+4x)[/tex]
2. [tex]60 + 12x[/tex]
Step-by-step explanation:
1. Let's just focus on one person at the moment. One of the friends bought a single shirt for $20, and 4 shirts that cost x dollars. Therefore, a single person's expense can be shown as:
[tex]20 + 4x[/tex]
Where x is the number of shirts the person bought.
Each of the three friends had the exact same expenses too, so we multiply this by three:
[tex]3 (20+4x)[/tex]
2. Simplifying the above equation just means multiplying each term in the parentheses by the 3 outside it, so 3 times 20 is 60, and 4x time 3 is 12x. Therefore, the simplified expression is:
[tex]60 + 12x[/tex]
Hope this helps!

Answer:
You need help with both or can I just help with one ?
Step-by-step explanation:
Answer:
14,275
1013
Step-by-step explanation:
1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2
Therefore you can write the following equation
4500(1.08)ⁿ where n is the number of years
we need is in 2015 and so n=15 so we have
4500(1.08)¹⁵=14274.5 which you should probably round to 14275
The second one is very similar to the first
to get from 1990 to 1991 you would multiply 5000*.93
so our equation would be
5000(.93)ⁿ where n is the number of years
1990-2012 is 22 so we have
5000(.93)²²=1012.96 which rounds to 1013

The perimeter of a triangle is 22cm. If one of the sides is 9cm,find the other sides if the area of the triangle is 20.976cm2
Answer:
Third side = 8.34 cm
Step-by-step explanation:
Given that,
The perimeter of a triangle, P = 22 cm
One side of a triangle, b = 9 cm
The area of the triangle, A = 20.976 cm²
The formula for the area of a triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times h\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times 20.976}{9}\\\\h=4.66\ cm[/tex]
Perimeter = Sum of all sides
9 cm + 4.66 cm + x = 22
x = 22 - 13.66
x = 8.34 cm
So, the third side of the triangle is 8.34 cm.
The rectangle on the right is a scaled copy of the rectangle on the left. Identify the
scale factor. Express your answer as a whole number or fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given question is incomplete; find the question in the attachment.
Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Corresponding dimension of preimage}}[/tex]
Scale factor = [tex]\frac{\text{Dimension of image rectangle B}}{\text{Corresponding dimension of preimage rectangle A}}[/tex]
From the figure attached,
Length of rectangle B = [tex]\frac{20}{3}[/tex]
Length of rectangle A = 20
Scale factor = [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, image rectangle A is dilated with by a scale factor of [tex]\frac{1}{3}[/tex].
John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?
The distance to Johns's grandmother's house is 90 miles.
SpeedSpeed is the ratio of total distance to total time taken, it is given by:
Speed = distance / time
Let x represent the speed that John used and d represent the distance, hence:
x = d/2
Also when taken 15 minute longer (0.25 hours):
x - 5 = d/(2 + 0.25)
x = d/2.25 + 5
Equating:
d/2 = d/2.25 + 5
d = 90 miles
The distance to Johns's grandmother's house is 90 miles.
