find an equation of the line that satisfies the given conditions. through (4, 9), parallel to the y-axis
We can write the line's equation as y = 5.
What is the slope of a line?The slope of a line can indicate how the line behaves and changes its value. As we know, an increasing line is inclined to the right, whereas a decreasing line is inclined to the left. Furthermore, the steeper the line, the greater the change in value with respect to the independent variable.
To find the equation:
With the given conditions, we find the equation of the line.
We begin by recognizing that we can write the line's expression in the point-slope form, which is expressed as:
[tex]y-y_0=m\left(x-x_0\right)[/tex]Where [tex]\left(x_0, y_0\right)[/tex] is the point through which the line passes and m is the slope We have already been given the point:
[tex]\left(x_0, y_0\right)=(4,5)[/tex]Which the line passes through.
We are also told that the line is parallel to the x-axis. The x-axis, as we know, is a horizontal line, indicating that the slope is zero, or m = 0.We now write the line's equation:
[tex]\begin{gathered}y-y_0=m\left(x-x_0\right) \\y-5=(0)(x-4) \\y-5=0 \\y=5\end{gathered}[/tex]
Therefore, we can write the line's equation as y = 5.

Tickets numbered 4, 5, 6......48, 49 are placed in a box and mixed thoroughly. One ticket is drawn from the box. Find the probability that the number on the ticket is:
(i) an even number (ii) A number less than 16
(iii) a perfect square (iv) a prime number less than 30.
Answer:
i) The probability that the number on the ticket is even is [tex]\mathbf{\frac{1}{2}}[/tex]
ii) the probability that the number on the ticket is a number less than 16 is [tex]\mathbf{\frac{6}{23}}[/tex]
iii) The probability that the number on the ticket is a perfect square is [tex]\mathbf{\frac{5}{46} }[/tex]
iv) the probability that the number on the ticket is a prime number less than 30 is [tex]\mathbf{\frac{4}{23} }[/tex]
Step-by-step explanation:
Tickets numbers are: 4, 5, 6......48, 49
So, total tickets in box = 46
We need to find probability that the number on the ticket is:
i) an even number.
Even number in tickets are: 4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48
Total number of favourable outcomes = 23
So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]
Total number of outcomes = 46
Number of favourable outcomes = 23
Putting values and finding probability
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{23}{46}\\Probability=\frac{1}{2}[/tex]
So, the probability that the number on the ticket is an even number is [tex]\mathbf{\frac{1}{2}}[/tex]
ii) A number less than 16
Even number in tickets are: 4,5,6,7,8,9,10,11,12,13,14,15
Total number of favourable outcomes = 12
So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]
Total number of outcomes = 46
Number of favourable outcomes = 12
Putting values and finding probability
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{12}{46}\\Probability=\frac{6}{23}[/tex]
So, the probability that the number on the ticket is a number less than 16 is [tex]\mathbf{\frac{6}{23}}[/tex]
iii) a perfect square
Perfect squares are: 4,9,16,25,36
Total number of favourable outcomes = 5
So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]
Total number of outcomes = 46
Number of favourable outcomes = 5
Putting values and finding probability
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{5}{46}[/tex]
So, the probability that the number on the ticket is a perfect square is [tex]\mathbf{\frac{5}{46} }[/tex]
iv) a prime number less than 30.
Prime numbers less than 30 are: 5,7,11,13,17,19,23,29
Total number of favourable outcomes = 8
So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]
Total number of outcomes = 46
Number of favourable outcomes = 8
Putting values and finding probability
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{8}{46}\\Probability=\frac{4}{23}[/tex]
So, the probability that the number on the ticket is a prime number less than 30 is [tex]\mathbf{\frac{4}{23} }[/tex]
Suppose 2a-3b = -23. Given that a and b are consecutive integers and a
Answer:
a = 20 and b = 21
Step-by-step explanation:
Given:
2a-3b = -23
a and b are consecutive
Find:
a and b
Computation:
a = b - 1
So,
2a-3b = -23
2(b-1)-3b = -23
2b - 2 - 3b = -23
-b = -21
b = 21
So
a = b - 1
a = 21-1
a = 20

Barbara photographs a bird. The bird measures 8.6 cm tall in the photo and is actually 52.4 cm tall. Approximately how long is the bird's beak if it measures 1.1 cm in the photo?
An actual measurement represents a reading that is taken manually at the physical thickness measurement location on the equipment.
Find the solution ?actual measurement = 8.6cm(bird's height), ? (beak)
photo measurement = 52.4(birds height), 1.1 (beak)
if 52.4 = 8.6
1.1 = 1.1 x 8.6

Step 1: Subtract 60x from both sides.
100x−200−60x>60x−120−60x
40x−200>−120
Step 2: Add 200 to both sides.

Find the side length of a cube with a volume of 422 yd ^3
Answer:
5.5 yd
Step-by-step explanation:
To find the side length of the cube, the volume is a clue. We know that all sides of a square are equal, and the volume of a cube is length×width×height. Since the length, width and height are all the same, we know it is V=x³. Since we know the volume, we can plug in and solve for x.
166=x³
In order to get x alone, we have to cube root both sides.
x≈5.5 yd

Reuben bought 5CDS that were each the same priceIncluding sales tax, he paid a total of \$81.50. Each CD had a tax of $0.60. what was the price of each cs before tax ?
Answer:
The price of each CD before tax is $15.70
Step-by-step explanation:
Given that:
Number of CDs bought by Reuben = 5
Cost of five CDs = $81.50
Sales tax on each CD = $0.60
Sales tax on 5 CDs = 0.60*5 = $3.00
Price of CDs without tax = 81.50 - 3.00 = $78.50
Price of each CD = [tex]\frac{Cost\ of\ CDs}{No.\ of\ CDs}[/tex]
Price of each CD = [tex]\frac{78.50}{5}[/tex]
Price of each CD = $15.70
Hence,
The price of each CD before sales tax is $15.70
2. Here are some equations that are related to `x-0.1x+2.70=56.70`. Each equation is a result of performing one or more moves on that original equation. Each can also be interpreted in terms of Noah's purchase.
Question isn't complete so we assume you wish to solve the equation above
`x-0.1x+2.70=56.70
Answer:
Step-by-step explanation:
To solve this equation
x-0.1x+2.70=56.70
We first find like terms and then subtract both sides of the equation
x-0.1x+2.70=56.70= 1x-0.1x+2.70=56.70
Add like terms
0.9x+2.70=56.70
Subtract both sides of equation
0.9x=56.70-2.70
Divide both sides
0.9x=54
x=54/0.9
x= 60
