On a coordinate plane, a graph decreases between (2.5, 2) and (4.5, 0.25).
How does this graph change between (2.5, 2) and (4.5, 0.25)?
Answers
The graph of the coordinate plane is attached below.
Any point on a plane can be uniquely identified by a pair of numerical coordinates using a cartesian coordinate system, which employs signed distances between two fixed perpendicular oriented lines and the point measured in the same unit of length.
The intersection of the ordered pairs serves as the origin of each reference coordinate line, sometimes referred to as an axis of the system or simply an axis (plural axes) (0, 0).The locations of the perpendicular projections of the point onto the two axes, which are displayed as signed distances from the origin, can also be used to derive the coordinates.The graph of the line decreases between (2.5, 2) and (4.5, 0.25) and the graph increases between (2.5, 2) and (4.5, 0.25)

Garcia's bike rentals, it cost $38 to rent a bike for 9 hours. How many hours of bike use does the customer get per dollar. If necessary, round the answer to the nearest hundredth
Answers
From the question, we were told that Garcia's bike rentals cost $38 to rent bike for 9 hours.
We are to find how many hours will a customer use the bike per dollar.
This can also be likened to calculating miles per gallon.
if i can drive 300 miles on 10 gallons of gas then my miles per gallon is 300/10 = 30 mpg.
So, hours per dollar is also a division problem too.
(9 hours)/($38)
= 9/38
= 0.2368
= 0.24 hours per dollar (to the nearest hundredth)
A table is made using the following two patterns.
Pattern x: Starting number: 3, Rule: add 3
Pattern y: Starting number: 6, Rule: add 6
Complete the table for the given patterns.
And then it asks to graph the points from 3 points
Answers
The rules of the patterns are 3 + 3x and 6 + 6y
How to complete the pattern?The patterns are given as:
Pattern x: Starting number: 3, Rule: add 3Pattern y: Starting number: 6, Rule: add 6For pattern x, we have the following highlights:
Start = 3
Rule = Add 3
This means that the nth term of pattern x is:
Pattern x = 3 + 3x
For pattern y, we have the following highlights:
Start = 6
Rule = Add 6
This means that the nth term of pattern y is:
Pattern y = 6 + 6y
The complete tableFor pattern x, set x = 0, 1, 2 and 3
So, we have
3 + 3x = 3 + 3(0) = 3
3 + 3x = 3 + 3(1) = 6
3 + 3x = 3 + 3(2) = 9
3 + 3x = 3 + 3(3) = 12
For pattern y, set y = 0, 1, 2 and 3
So, we have
6 + 6x = 6 + 6(0) = 6
6 + 6x = 6 + 6(1) = 12
6 + 6x = 6 + 6(2) = 18
6 + 6x = 6 + 6(3) = 24
Next, we plot the graphs of both patterns (see attachment) where the blue line represents pattern 1, and the other represents the second pattern

Step-by-step explanation:
1/3 = 3/15
2/5 = 6/15
1 - 3/15 - 6/15 = 6/15
6/15 = 24600
24600 ÷ 6 × 15 = 61500
Answer:

Step-by-step explanation:
Forming algebraic equation and solving:
Let the income = x
Amount spent on housing = (1/3) of the income
[tex]\sf = \dfrac{1}{3}x[/tex]
Amount spent of daily expenditure = (2/5) of the income
[tex]\sf =\dfrac{2}{5}x[/tex]
Income = Savings + housing expenditure + daily expenditure
Income - housing expenditure - daily expenditure = savings
[tex]\sf x - \dfrac{1}{3}x-\dfrac{2}{5}x=24600\\\\\\\dfrac{x*15}{1*15}-\dfrac{1*5}{3*5}x-\dfrac{2*3}{5*3}x = 24600\\\\\\[/tex]

3. 3
Answer: 1 = X
Step-by-step explanation:
Equation: -5 <3× -8
First Step: You must add 8 to -8 and move it to both sides. The reason why we do this is because on the left side we have 1 number and on the right side we have 2 numbers. We see that the right side has more numbers than the left, so we must move the -8 turning it to a positive 8 (8-8 cancels each other making 0) and adding the +8 in -8 to -5 as well, since we're adding to both sides.
Second Step: Since we added 8 to -5, it equals 3 now 8-5=3. Changing the equation to 3 <3x. Now we have to divide 3 to both sides as well, because we want the x to be by itself. So, 3 ÷ 3 = 1 and 3x ÷ 3 = x

Answers
The height of a tree whose shadow is 20m shorter when the angle of elevation of the sun is 60 is 17.3 meters.
What is elevation?The elevation is the distance above sea level. They are usually measured in meters or feet.
Let t be the height of the tree, then the length of the shadow will be:
Shadow length = t/tan(α)
where α is the angle of elevation. The difference in shadow lengths is:
20 m = t/tan(30°) -t/tan(60°) = t(√3 -1/√3)
= (20 m)/(2/√3) = 10√3 m
= 17.3 m

See details:
The value of the greater integer will be 10.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The algebraic expression is,
'' An integer is subtracted from 8 times the next consecutive integer, the difference is 71.''
Now,
Let a number = x
Then, Its consecutive number = (x + 1)
So, We can formulate;
⇒ 8 (x + 1) - x = 71
Solve for x as;
⇒ 8x + 8 - x = 71
⇒ 7x + 8 = 71
⇒ 7x = 71 - 8
⇒ 7x = 63
⇒ x = 9
Thus, The value of greater number = x + 1
= 9 + 1
= 10

Answers
If one of the daughters marries a non-bald man and they have a son, the chance that the son will become bald as an adult is 0%
If the couple has a daughter, the chance that she will become bald as an adult is 0%
In the question, we have been given that the neither the father nor the mother is bald, and out of the four children only one son is bald, but the other son and the two daughters are not bald, now we solve the following:
Part a
A chance that the son will become bald as an adult:
If the daughter has no bald gene (XX), and she marries a non bald man then there is 0% chance that the son will become bald as an adult because neither the mom nor the dad has the baldness gene
Part b
The chance that she will become bald as an adult:
If the daughter having a bald gene ([tex]X^{b} X[/tex]) marries a non bald (XY)man then also there is a 0% chance that the daughter will be bald as an adult. As the baldness is a recessive trait, for the daughter to be bald she needs to have two baldness gene( one from father and one from mother). And since this is not the case the daughter might have baldness gene but the phenotype will be non-bald.

Reorder the terms:
7 + 2x = -3 + 4x
Solving
7 + 2x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
7 + 2x + -4x = -3 + 4x + -4x
Combine like terms: 2x + -4x = -2x
7 + -2x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
7 + -2x = -3 + 0
7 + -2x = -3
Add '-7' to each side of the equation.
7 + -7 + -2x = -3 + -7
Combine like terms: 7 + -7 = 0

Answers
Answer:

Step-by-step explanation:
You want to know the number of feet in a 5 km race, rounded to the nearest hundred. You are given conversion factors 5280 ft = 1 mi = 1.61 km.
Unit conversionUnit conversion can be done by multiplying by a conversion factor whose numerator is equal to its denominator, and that cancels unwanted units, replacing them with units you want.
[tex]5\text{ km}=5\text{ km}\times\dfrac{5280\text{ ft}}{1.61\text{ km}}\approx16397.5\text{ ft}\approx\boxed{16,\!400\text{ ft}}[/tex]
__
Additional comment
Both of the given conversions are equal to 1 mile, so their ratio is 1. We put feet on top of the fraction, because that is the unit we want. The km value is in the denominator so the km units in numerator and denominator cancel.
The conversion for km is 1 mi = 1.609344 km (exactly). The actual conversion to ft will give 16,404 76/381 ft. This has a very long repeating decimal fraction.

Answers
The mattress has a total cost of $24.28
How to determine the total cost for the mattress?From the question, the given parameters are:
Cost of a mattress = $74.95
Markdown = 70%
Sales tax in oak grove = 8%
Using the sales tax and the markdown, the total cost for the mattress is calculated using
Total cost of mattress = Cost of a mattress * (1 + Sales tax) * (1 - Markdown )
Substitute the known values in the above equation
So, we have the following equation
Total cost of mattress = 74.95 * (1 + 8%) * (1 - 70%)
Evaluate the products
Total cost of mattress = 24.28
