Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 530 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
c(x) = 18x -10
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
c(x) = 18x - 10
comparing with the slope-intercept form of the line equation
rate of change = 18c(x) or y represents the cost'x' represents the number of ticketsAssuming the total cost i.e. c(x) = $530
In order to determine the value of x, set c(x) = 530
i.e.
530 = 18x -10
switch sides
18x - 10 = 530
add 10 to both sides
18x - 10 + 10 = 530 + 10
18x = 540
Divide 18 to both sides
18x/18 = 540/18
x = 30
Therefore, if you can buy x = 30 tickets if you pay 530 dollars.
What is an equation of the line that passes through the point (-2, -6) and is
parallel to the line x + 2y = 8?
Answer:
The equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]
Step-by-step explanation:
We need to write an equation of the line that passes through the point (-2, -6) and is parallel to the line x + 2y = 8
We need to find slope m and y-intercept b for the new line.
First we need to find slope m of the new line.
The given line x+2y=8 is parallel to new line.
When lines are parallel, there slope is same.
First writing equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept
[tex]x+2y=8\\2y=-x+8\\y=-\frac{1}{2}x+\frac{8}{2}\\ y=-\frac{1}{2}x+4[/tex]
Now comparing with [tex]y=mx+b[/tex] the slope is : [tex]m=-\frac{1}{2}[/tex]
Now finding y-intercept b
Using point (-2,-6) and slope [tex]m=-\frac{1}{2}[/tex] we can find y-intercept
[tex]y=mx+b\\-6=-\frac{1}{2}(-2)+b\\-6=1+b\\b=-6-1\\b=-7[/tex]
So, we get y-intercept b = -7
Now the equation of required line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -7 is:
[tex]y=mx+b\\y=-\frac{1}{2}x-7[/tex]
So, the equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]

Step-by-step explanation:
quantity: the amount of smth
Hope it helps, have a great day!
The quantity resulting from the expression "32 minus 16 multiplied by 9" is -112.
In the given context, "quantity" refers to a specific numerical value or amount. It represents a numerical value that can be measured, counted, or expressed in terms of units. In this case, the quantity is being used to describe the result of a mathematical operation.
In general, when we refer to a quantity, we are focusing on the numerical value itself, irrespective of the units or context. It provides a way to quantify or express a particular amount or value in a given situation.
In the expression "32 minus 16 multiplied by 9," the quantity refers to the value obtained from performing the mathematical operation. To evaluate this expression, we follow the order of operations, which dictates that multiplication should be performed before subtraction:
32 - 16 x 9
Multiplying 16 by 9 gives us 144, and subtracting that from 32 yields the quantity:
32 - 144 = -112
Therefore, the quantity resulting from the expression "32 minus 16 multiplied by 9" is -112.

The perimeter of a rectangle is 64 feet. The length is two more than double the width. Find the dimensions of the rectangle.
Answer:
Length = 22 ; width = 10
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Perimeter = 64 feets
Length = 2 + (2*width)
Let :
Length = l ; width = w
Perimeter = 2((2 + (2w)) + w)
64 = 2(2 + 3w)
64 = 4 + 6w
64 - 4 = 6w
60 = 6w
w = 60/6
w = 10
Width = 10
Length = 2 + (2*width) = 2 + (2*10) = 2 + 20 = 22

Taylor has $4 worth of dimes and quarters. She has 2 more quarters than
dimes. Graphically solve a system of equations in order to determine the
number of dimes, x, and the number of quarters, y, that Taylor has.
Answer: Taylor has 10 dimes and 12 quarters.
Step-by-step explanation: you should end up with the equation y = x + 2 which is where it explains that he had two more quarters than dimes.
Then, your other equation starts with .10x +0.25y = 4 “, but then simplified, which should give u y = -2/5x +16. Once you graph both the top and this equation, they should intersect at the 4, which leads back to your money amount of 4 dollars.

Solve for x:
4(1 – x) + 2 x = -3( x + 1)
Answer:
4(1 – x) + 2 x = -3( x + 1)
first do 4 time 1= 4
then do 4 times x =4x
now the equation should look like this
4-4x+2x=-3(x+1)
then do the other side of the equation

Why move an expression to the right?
We want to move an expression to the right to write the equation in a specific way.
The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality
Step 1
Example
take the equation:
[tex]x+a=b[/tex]
We want the expression a to be on the right hand side of the equation.
Step 1
example(cont)
To move the expression to the right -hand side, use the addition property , and add -a to both sides of the equation:
[tex]x+a+(-a)=b+(-a)[/tex]
Simplify the left hand side and remove the parentheses on the right hand side:
[tex]x+a+(-a)=b+(-a)\\x=b-a[/tex]
Now the expression a is on the right hand side :
[tex]x=b-a[/tex]
Step 2:
Notice! when comparing the beginning and the ending equation, it seems like we just moved the expression to the right hand side and changed its sign:
[tex]x+a=b\\x=b-a[/tex]
This is a shorter way to use the same property.
Now came back to the original equation
[tex]4-2x+3x=-3[/tex]
Move constant to to the right hand side and change its sign
[tex]-2x+3x=-3-4[/tex]
collect like terms
[tex]x=-3-4[/tex]
calculate the difference
[tex]x=-7[/tex]
Why move a constant to the right?
We want to move a constant to the right because the mathematicians agreed upon a convention that the constants in the equation and inequalities always need to be on the right-hand side.
The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality.
Step 1
example
Take the equation:
[tex]x+3=5[/tex]
We want the constant 3to be on the right hand side of the equation.
Step 1
example (cont)
To move the constant to the right-hand side, use the addition property, and add -3 to both sides of the equation:
[tex]x+3+(-3)=5+(-3)[/tex]
Simplify the left-hand side and remove the parentheses on the right - hand side:
[tex]x+3+(-3)=5+(-3)\\x=5- 3[/tex]
Now , all the constants are on the right- hand side:
[tex]x=5-3[/tex]
Step 2
Notice! when comparing the beginning and the ending equation, it seems like we just moved the constants to the right hand side and change its sign:
[tex]x+3=5\\x=5-3[/tex]
This is a shorter way to use the same property.

2 numbers are in ratio 2 is to 4 if their sun is 147 then what i the largest number?
Answer:
The larger number is 98
Step-by-step explanation:
Let the numbers be a and b
a/b= 2/4
4a = 2b ------- 1
a + b = 147 -----2
a= 147 - b -------3
Substitute equation 3 into 1
4(147 -b) = 2b
588 - 4b = 2b
588= 2b + 4b
588 = 6b
b= 588/6
b= 98
Substituting b= 98 into 1
4a = 2(98)
4a = 196
a= 49
The larger number is 98

Answer:
y=2x
Step-by-step explanation:
y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)
Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.
Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!

If the side length of any equilateral triangle is increase by 7% then the area will be change in which percent? How do we do this type of maths?
Answer:
Look at the attachment
The bottom equation states that:
Triangle Area = side^2 * (sqr root 3) / 4 or
Triangle Area = side^2 * .4330127..
So, we'll say the side originally equaled 1 and the new length is 7% longer ot it equals 1 + .07 or 1.07
Looking at the formula:
Triangle Area = 1.07^2 * .4330127...
the .4330127 doesn't change but the side increases to 1.07
and the change in area is 1.07^2 or 1.1449 times larger.
So, the area is 14.49% larger.
