It represents a linear function because there is a constant rate of change.
Step-by-step explanation:
A linear function is arranged in or extending along a straight or nearly straight line.
So if the numbers keeps increasing, which it is, it will be rising in an almost complete straight line on a graph. That means it is a linear function because the numbers keep increasing.

The length of a rectangle is 6 feet more than three times the width of the
rectangle. The length of the rectangle is 24 feet. What is the width of the
rectangle?
Answers
Answer:
width = 6 feetStep-by-step explanation:
let l be the length of the rectangle
let w be the width of the rectangle
The statement
The length of a rectangle is 6 feet more than three times the width of the
rectangle is written as
l = 6 + 3w
From the question
l = 24 feet
Substitute the value into the above formula and solve for the width
That's
24 = 6 + 3w
3w = 24 - 6
3w = 18
Divide both sides by 3
w = 6
Therefore
width = 6 feetHope this helps you

Answer:
The area of the hubcap is 196π or 615.7521601
Step-by-step explanation:
You can use A=πr² to find the area of a circle. So that would mean that A equals 14². 14²=196. If the answer is in π form, then the answer is 196π. If not then its 196·π. 196·π=615.7521601

The area of the hubcap is about 615.44 cm²
Step-by-step explanation:
A = πr²
Use the formula.
A = π(14)²
Substitute. Use 14 for r.
A ≈ 3.14 × 14²

the lines on a 2 cup liquid measuring cup divide each cup into eighths. if you measure 1 3/4 cups of water, between which 2 quantities can you be certain that your exact measurement will be?
Answers
Answer:
13 th and 14 th
Step-by-step explanation:
Since the line divides the cup into one - eighth
Thus a measurement of 1 3/4
The number of 1/8th's obtainable from 1 3/4 :
1 3/4 = 7/4
7/4 divided by 1/8th
7/4 ÷ 1/8
7/4 × 8/1
= 56/4 = 14
14 gives the upper limit of the line starting from the bottom, Therefore, a measurement of 1 3/4 should be between the 13 th and 14 th line. Since the bottom of the cup will have no line.

Johnathan makes $27 per hour and works 25 hours per week. Every week, he has to sell 20 items. If he sells more than 20 items in a week, he receives a commission of 14% on each set of additional 5 items he sells. This week he worked for 25 hours, he sold 25 items, and he made $1,000 in sales beyond the required 20 items. Which equation will help Johnathan to compute this weeks income?
Answers
Answer:
Total income = 27 [tex]\times[/tex] 25 + 14% of $1000= $815
Step-by-step explanation:
Number of hours for which Johnathan worked = 25
Salary for each hour = $27
So, income for 25 hours = 25 [tex]\times[/tex] 27 = $675
Now, it is given that he has sold 25 items.
Sales made beyond the 20 items = $1000
Additional income for additional sales = 14% on each set of 5 items
He has sold exactly 5 additional items that means 1 set of 5 additional items.
So, Additional income for additional sales = 14% [tex]\times[/tex] 1000 = $140
Therefore, total income of this week = Income for 25 hours + Income due to additional sales of 5 items
Therefore Total income = 27 [tex]\times[/tex] 25 + 14% of $1000= $815

find the range of each of the following function. All the function are definied for all values of x.
f(x) = 3(x+5)² +2
Can you give the answer and explanation?
what does 'all the function are definied for all values of x'?
Heldpdlsoemss
Answers
Answer:
y ≥ 2
Step-by-step explanation:
The range is all of the values that f(x) can have. In order to find the range, let's first find the vertex. That's pretty easy to do since f(x) is already written in vertex notation (vertex notation is f(x) = a(x - c)² + d where (c, d) is the vertex). Since c = -5 and d = 2, the vertex is (-5, 2). Because the value of a is positive (a = 3 in this case, which is positive) we know that the parabola opens upward, therefore the vertex is the minimum. This means that the y-coordinate of the vertex is the smallest possible y-value of the function, therefore, since the y-coordinate of the vertex is 2, the range is y ≥ 2. Note that we use ≥ and not >, this is because y can be 2, therefore, it is included in the solution set.
Answer:
Hey there!
First, we must understand what range is. Range is just another word for all the possible y values of the equation.
This equation, f(x) = 3(x+5)² +2 is in vertex form. We see that this creates a parabola with a vertex at (-5, 2) and opens up.
Thus, the range of this graph would be: [2,∞) in interval notation. Note, the [ is used for greater than or equal to, or less than or equal to, and the ")" is used for less than or greater than.
We use ) for ∞, because ∞ is just a concept, not a real number.
Finally, all functions are defined for all values of x means that this is an f(x) function, and the f(x) is equal to something that can be written in terms of x.

Solve for x in the equation below(all in picture).
Answers
Answer:
x = - 5, x = 2
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log ([tex]\frac{x}{y}[/tex] )
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
note that log x = [tex]log_{10}[/tex] x
Given
log (x² + 3x) - log10 = 0, then
log([tex]\frac{x^2+3x}{10}[/tex] ) = 0, thus
[tex]\frac{x^2+3x}{10}[/tex] = [tex]10^{0}[/tex] = 1 ( multiply both sides by 10 )
x² + 3x = 10 ( subtract 10 from both sides )
x² + 3x - 10 = 0 ← in standard form
(x + 5)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 2 = 0 ⇒ x = 2
Solution is x = - 5, x = 2
Answer:
The equation has the solution(s) x = - 5, and x = 2
Step-by-step explanation:
Let's start by adding log(10) to either side of the equation --- (1)
[tex]\log _{10}\left(x^2+3x\right)-\log _{10}\left(10\right)+\log _{10}\left(10\right)=0+\log _{10}\left(10\right)[/tex]
= [tex]\log _{10}\left(x^2+3x\right)=\log _{10}\left(10\right)[/tex]
If you recall, one property proves that [tex]\log _{10}\left(10\right):\qu 1[/tex]. We can substitute this value back into the simplified equation --- (2)
[tex]\log _{10}\left(x^2+3x\right)=1[/tex]
We can also apply the logarithmic definition, If logₐ(b) = c then b = aᶜ. Using this definition we receive a further simplified equation --- (3)
[tex]x^2+3x=10^1[/tex]
[tex]x^2+3x=10[/tex]
Solving for the expression we receive the solution(s) x = 2, and x = - 5, our first option.
Note : The first solution is correct, but I wanted to take a slightly different approach

Four consecutive even integers are such that the sum of the second and fourth is 76. What is the sum of the first and third integers?
Answers
Answer:
72
Step-by-step explanation:
Consecutive even integers have a difference of 2 between them
let n be the first integer, then
n + 2, n + 4, n + 6 are the second, third and fourth, then
n + 2 + n + 6 = 76 ( sum of second and fourth )
2n + 8 = 76 ( subtract 8 from both sides )
2n = 68 ( divide both sides by 2 )
n = 34
Thus the 4 even integers are
34, 36, 38, 40
sum of first and third = 34 + 38 = 72

Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
Use this information for problems 1 and 2. When full, one of the pools at Sapphire Island will hold 43,000 gallons of water. The pool currently holds 20,000 gallons of water and is being filled at a rate of 130 gallons per minute.

\large 130\left(60h\right)-20000=43000
d
\large 130\left(60h\right)+20000=43000
Answers
Answer:
The correct option is;
d. 130·(60·h)+2000 = 43000
Step-by-step explanation:
The volume of water held by a pool at Sapphire island = 43,000 gallons
The volume of water the pool currently holds = 20,000 gallons
The rate at which the pool is being filled = 130 gallons/minute
The equation to find h, the number of hours it will take to fill the pool from its current level can be written as follows;
The rate at which the pool is being filled in gallons per hour = 130 × 60 gallons/hour = 7800 gallons/hour
We have;
The volume of water pumped in h hours = (130×60) gallon/hour × h hour = 130×60×h gallons
Whereby we want the total volume of water in the pool to be 43,000 gallons, we add the volume of water obtained from pumping for hours to the volume of water already in the pool, to get 43,000 gallons as follows;
130×60×h gallons + 20,000 gallons = 43,000 gallons
Therefore, the correct option is 130·(60·h)+2000 = 43000.
