Answer:
f(x)= $70 - $1.5*x
Step-by-step explanation:
You know your friend spends $ 5 to enter the fair and $ 15 for food. So the total you spent is given by:
$5 + $15= $20
Knowing that the trips at the fair cost $ 1.50 per trip, and with x being the number of trips, then the cost after x trips will be:
$1.5*x
So the money spent after x rides can be expressed as:
$20 + $1.5*x
Knowing that your friend has $90 when he goes to the fair, to calculate the amount of money he has left after x rides, the amount taken to the fair and the amount spent is subtracted:
$90 - ($20 + $1.5*x)
$90 -$20 -$1.5*x
$70 - $1.5*x
By calling the function f(x) used to determine the amount of money left after x trips, you can finally express:
f(x)= $70 - $1.5*x
a rectangle is 25 feet long its area 375 square feet.
What is the perimeter of the rectangle
Area = length x width.
Divide the area by the length of find the width.
Width = 375/25 = 15 feet.
The perimeter is the sum
Of the 4 sides.
Perimeter = 25 + 25 + 15 + 15 = 80 feet.
The perimeter of a rectangle is 80 feet.
Given that, the length of a rectangle=25 feet and area of the rectangle=375 square feet.
We need to find the perimeter of a rectangle.
What is the formula to find the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
We know that, the area of a rectangle=length×width
Now, the area of a rectangle=25×width
⇒375=25×width
⇒Width=15 feet
So, perimeter = 2(25+15).
=80 feet
Therefore, the perimeter of a rectangle is 80 feet.

1. Square of a Binomial
Symbols/Pattern:
(a + b)2 = a2 + 2ab + b2

In the pattern, if a is the first term and b is the last term, then the square
of a binomial consists of:
a) the square of the first term (a);
b) twice the product of the first and last terms (2ab); and
c) the square of the last term (54).

The graph is posted now.
Answer:
where is the graph itself?
Answer:
see below
Step-by-step explanation:
Pre-image: A(3, 8), B(3, 3), C(7, 3)
Reflection in the x-axis changes the y-coordinate sign:
A'(3, -8), B'(3, -3), C'(7, -3)
Reflection in the y-axis changes the x-coordinate sign:
A''(-3, -8), B''(-3, -3), C''(-7, -3)

Comment
We have assumed that the first image is reflected again to get the second image. If the second image is supposed to be a reflection of the pre-image, then only the sign of x will change from the pre-image coordinates.
There are no "rotated" images; only reflected ones. (Though, after the second reflection, the image could be considered to be a 180° rotation of the pre-image.)

Step-by-step explanation:
A company rents out 17 food booths and 21 game booths at the county fair. The fee for a food booth is $75 plus $10 per day. The fee for a game booth is $95 plus $4 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
Food booth= (75+10d)17
Game booth= (95+4d)21
Step-by-step explanation:
GAME BOOTH
$95 initial fee plus $4 per d amount of days
f(x)=95+4d
Multiply the expression by 21 because you have 21 game booths
FOOD BOOTH
$75 initial fee plus $10 per d amount of days
f(z)=75+10d)
multiply this expression by 17 because their are 17 food booths

This was a wrong answer, Sorry.
Answer:
75
Step-by-step explanation:
if 15 is no more than a number t divided by 5 then you multiply 15 by 5 giving you the answer for t.
15=t/5

A square has a diagonal that measures 18 inches. To the nearest tenth, what is the length of one side
of the square?
Answer:
18/sqrt(2)
Step-by-step explanation:
Divide the square into two congruent right triangles:
a and b are the sides of the triangle
since we know that a=b
then the right triangle is isosceles
meaning that the theorem of the 45-45-90 triangle is applicable
so then we can say that 18/sqrt(2) = a = b

It normally takes Julius 2 hours to mow the yard, but because he is in a hurry he asks his son, Marcos, to help him. If just his son was doing the yard work it would take him 3 hours. How long will it take if both are working together? Use the formula 1/T_1 +1/T_2 =1/T_both where T_1 is the time required for Julius to complete the job alone, T_2 is the time required for Marcos to complete the job alone, and T_both is the time required to complete the job when they both work together. Answer as a decimal, rounded to one decimal place.
Answer: 1.2 hours
Step-by-step explanation:
Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]
Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]
Let the time taken by both to complete the job together = T
[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]
[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]
Hence, it will take 1.2 hours to complete the job by working together.

Which equation has the same solution as 10x-x+5=4110 x − x + 5 = 41?
Answer:
d
Step-by-step explanation:
The equation having same solution as linear equation 10x -x + 5 =41 is equation: 9x +5 = 41
What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting, multiplying, dividing same number to both sides.
Given equation 10x -x + 5 =41
⇒ (10-1) x = 41-5
⇒9x = 36
⇒ x= 36/9 = 4
From given options :
1. 10x + 5 =41⇒ 10x = 36 ⇒ x = 36/10 = 3.6
2. 10x - 5 +x = 41 ⇒ 11x = 41+5⇒ 11x = 46 ⇒ x = 46/11
3. 9x = 46 ⇒ x = 46/9
4. 9x +5 = 41⇒ 9x = 41-5 = 36 ⇒ 9x = 36 ⇒ x = 36/9 = 4
Therefore, the equation 9x +5 = 41 has same solution x= 4 as the given solution.
