Answer:
A) $18
B) [tex]y=2.50x+18[/tex]
C) Coefficient of x-term represents the cost for each ride ticket and constant term represents the cost of admission to the fair.
Step-by-step explanation:
(A)
The county fair charges $2.50 per ticket for the rides and Henry bought 15 tickets for the rides.
So, the total cost of the 15 tickets will be: [tex](\$2.50*15)=\$37.50[/tex]
He spent total $55.50 on ride tickets and fair admission.
So, the cost of admission to the fair will be: [tex](\$55.50-\$37.50)=\$18[/tex]
(B)
If [tex]x[/tex] represents the number of ride tickets and [tex]y[/tex] represents the total cost, then the cost for [tex]x[/tex] number of ride tickets is [tex]\$2.50x[/tex]
So, the linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission will be: [tex]y=2.50x+18[/tex]
(C)
In the above linear equation, coefficient of x-term is 2.50, which represents the cost for each ride ticket.
And the constant term is 18, which represents the cost of admission to the fair.

the room shown below right is 14ft by 10ft. Find the dimensions of each piece of furniture to the nearest tenth.
The dimension of dresser is :
Length is 6.0 feet
width is 3.0 feet
The dimension of bed is :
Length is [tex]5\sqrt{2}[/tex] = 7.1 feet
Width is [tex]4\sqrt{2}[/tex] = 5.7 feet
The dimension of table:
Length is [tex]2\sqrt{2}[/tex] = 2.8 feet
Width is [tex]2\sqrt{2}[/tex] = 2.8 feet
Answer:
A). Dimensions of the bed = 7.1 ft × 5.7 ft
B). Dimensions of table = 2.8 ft × 2.8 ft
C). Dimensions of the dresser = 6ft × 3ft
Step-by-step explanation:
Dimensions of the room are 14 ft by 10 ft.
We have to find the dimensions of each furniture.
First we take the bed.
Length of the bed = [tex]\sqrt{(5)^{2}+(5)^{2}}[/tex]
= [tex]\sqrt{25+25}[/tex]
= [tex]\sqrt{50}[/tex]
= 7.07 ft ≈ 7.1 ft
Width of the bed = [tex]\sqrt{4^{2}+4^{2}}[/tex]
= [tex]\sqrt{16+16}[/tex]
= [tex]\sqrt{32}[/tex]
= 5.7 ft
We take another furniture table which is in the square shape,
Side of the table = [tex]\sqrt{2^{2}+2^{2}}[/tex]
= [tex]\sqrt{8}[/tex]
= 2.8 ft
Therefore, each side of the table is 2.8 ft
Length of the dresser = 6 ft
Width of the dresser = 3 ft

consider the following equation: f(x)=x^2+4\4x^2-4x-8 name the vertical asymptote(s)
ANSWER
The vertical asymptotes are
[tex]\Rightarrow x=2\:or\:x=-1[/tex]
EXPLANATION
We have
[tex]f(x)=\frac{x^2+4}{4x^2-4x-8}[/tex]
For vertical asymptotes we set the denominator to zero and solve the quadratic equation;
[tex]4x^2-4x-8=0[/tex]
[tex]\Rightarrow x^2-x-2=0[/tex]
We split the middle term to obtain,
[tex]x^2+x-2x-2=0[/tex]
[tex]\Rightarrow x(x+1)-2(x+1)=0[/tex]
[tex]\Rightarrow (x-2)(x+1)=0[/tex]
[tex]\Rightarrow x=2\:or\:x=-1[/tex]
Therefore the vertical asymptotes are
[tex]x=2\:or\:x=-1[/tex]
The vertical asymptotes are x = 2 and x = -1
How to determine the vertical asymptote?[tex]f(x)=\frac{x^2+4}{4x^2-4x-8}[/tex]
Set the denominator to 0
[tex]4x^2-4x-8 = 0[/tex]
Divide through by 4
[tex]x^2-x-2 = 0[/tex]
Expand
[tex]x^2+x-2x-2 = 0[/tex]
Factorize
[tex]x(x+1)-2(x+1) = 0[/tex]
Factor out x + 1
[tex](x-2)(x+1) = 0[/tex]
Solve for x
x = 2 or x = -1

Hey! I was wondering if someone could explain to me how solving two-step inequalities works. Thanks!
Here is the inequality:
[tex]-2x+6<20[/tex]
You're looking for x. To find it, you have to remove everything on the same side of the variable. The only thing with it is positive 6. To remove it, you have to do the opposite of it, which is -6, which is also the same as subtracting 6. Subtract 6 from both sides:
[tex]-2x+6-6<20-6 \\-2x<14[/tex]
Now you have -2x. When you have a negative variable, the inequality sign changes. Change the sign:
[tex]-2x<14 \rightarrow -2x>14[/tex]
You're looking for x alone. To leave x alone, you have divide both sides by -2 since the variable is -2x. Divide both sides by -2:
[tex]-2x \div -2 > 14 \div -2 \\\\x>-7[/tex]
When dividing a negative number number by a positive or vice versa, the result is ALWAYS negative. That's why in your answer, it's -7.
Your answer is x > -7

What is the measure of angle a?
A. Cannot be determined
B. 45•
C. 15•
D. 60•
As all angles of the triangle have to give 180 ° and, as the triangle is equilateral (all the angles are equal), the three angles have the same amplitude. 180 ÷ 3 = 60
So, the answer is D.
The measure of angle a (x) is 60 degrees when all sides of triangle are equal The correct answer is option D: 60°.
Since all three sides of the triangle ABC have equal lengths (15 units each), we can determine that this is an equilateral triangle. In an equilateral triangle, all three angles are congruent, meaning they have the same measure.
Let's represent the measure of angle a as "x."
In an equilateral triangle, the sum of all three angles is 180 degrees. So, we can write the equation:
x + x + x = 180
Combine like terms:
3x = 180
Now, divide by 3 to solve for x:
x = 180 / 3
x = 60
Therefore, the measure of angle a (x) is 60 degrees.
The correct answer is option D: 60°.

abigail has 16 shoes use repeated subtraction to show how many pairs of shoes Abigail has
Hello!
Here is how we solve this question.
We know that 2 shoes = 1 pair
So we subtract 2 from 16 until we reach 0, and count how many times we subtracted.
16-2=14
14-2=12
12-2=10
10-2=8
8-2=6
6-2=4
4-2=2
2-2=0
After we do repeated subtraction we find that Abigail has 8 pairs of shoes!
Hope this helps you with your question.
Since shoes comes in pairs, then the number of shoes Abigael has would be obtained by subtracting 2 from 16 until we obtain 0. Hence, the number of shoes she has is 8.
The total number of shoes = 16
Shoes are in pairs ; Hence 1 pair of shoe = 2 shoes
Using repeated subtraction :
1 ; 16 - 2 = 14
2 ; 14 - 2 = 12
3; 12 - 2 = 10
4; 10 - 2 = 8
5; 8 - 2 = 6
6; 6 - 2 = 4
7; 4 - 2 = 2
8; 2 - 2 = 0
Therefore, the Number of shoes Abigael has is 8

B. [(-3,3)], [(3,3)], [(0,0)], [(1,1)], [(-1,1)]
C. [(-2,5)], [(-1,4)], [(0,3)], [(-1,2)], [(-2,1)]
Both A and B represent functions, as the same x value is not used twice.
However, with option C, the x value -2 is used twice, and thus it is not a function.
The concept of functions in mathematics is determined by whether each input (or 'x' value) corresponds to exactly one output (or 'y' value). Upon examination, the sets of ordered pairs in option A qualify as functions, while the sets in options B and C do not.
Explanation:A function in Mathematics is a relation between a set of inputs and a set of outputs where each input is related to exactly one output. In your question, you have three different sets of ordered pairs. Let's examine them.
A. [(-2,3)], [(-1,5)], [(0,7)], [(1,9)]
Here every 'x' value is paired with only one 'y' value, so this one is a function.
B. [(-3,3)], [(3,3)], [(0,0)], [(1,1)], [(-1,1)]
For this one, we see that 'x' values -1 and 1 are both paired with 'y' value 1. This implies that a single 'x' value has more than one 'y' value which is not allowed for a function. So this one is not a function.
C. [(-2,5)], [(-1,4)], [(0,3)], [(-1,2)], [(-2,1)]
This one is similar to the second case where 'x' values -1 and -2 are both paired with multiple 'y' values. So, this one is not a function either.
So, only the first set constitutes a function.
