what number will the x-coordinate always be in any point that is a y-intercept? Explain!
1) what is the x-coordinate of any y-intercept?
2) explain why that is always the x-coordinate of a y-intercept
For a y-intercept, the x-coordinate will always be 0.
The y-intercept is the point that a line or a function crosses the imaginary line of y, which is between x = -1 and x = 1.
This point is at x = 0, and every y-intercept will always have an x-value of 0, as that is what makes it a y-intercept.
The x-coordinate of any y-intercept is always 0. This is because the y-intercept is the point where the line crosses the y-axis, and along that axis, the x-coordinate never changes from 0.
Explanation:The x-coordinate of any y-intercept is always 0. This is due to the definition of a y-intercept. A y-intercept is a point where the line crosses the y-axis. The x-axis and y-axis intersect at the point (0,0) and along the y-axis, the x-coordinate is always 0 regardless of where you are on that axis.
Imagine a horizontal line across any scatter plot. As this line moves up or down along the y-axis, the x-coordinate remains at 0, because it is not moving left or right along the x-axis. Therefore, this makes the x-coordinate of any y-intercept always 0.

Cost = initial fee + hourly charge * hours
Cost = 500 + 50h
Elegant Homes
Cost = initial fee + hourly charge * hours
Cost = 0+ 75h
Cost = 75h
Set the costs equal
500+ 50h = 75h
Subtract 50 h from each side
500 = 25h
Divide by 25
500/25= 25h/25
25 =h
The costs are equal at 20 hours
If less than 20 hours it costs less at Elegant homes.
If more than 20 hours it costs less at Rock the house

David sells two calculators for ₹1500 each .He earns a profit of 25% on
one and suffers a loss of 25% on the other. Find his total profit or loss on
the whole deal. Also calculate it as a percentage
Answer:
gain = 0
% = 0
Step-by-step explanation:
Profit
He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%
₹1500 * 125/100 = ₹187500/100 = ₹1875
Loss
Here he sells it for 25% less than the selling price he wanted.
100% - 25% = 75%
₹1500 * 75/100 = ₹112500/100 = ₹1125
Discussion
He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.
What he actually accomplishes is ₹1125 + ₹1875 = ₹3000
So he has a net gain (loss) of 0.
The % is 0

A taxi company charges $2.50 plus $1.10 for each mile driven.Weite an equation to represent this situation. Use this equation to determine how far you can travel if you have $10.00
The equation representing the taxi company's charges is y = 2.50 + 1.10x. With $10, you can afford to travel approximately 6.82 miles.
Explanation:The taxi company's charges can be represented by a simple linear equation. The basic charge of $2.50 is the y-intercept of the equation, which means it's the starting point before any miles are driven. The $1.10 per mile charge, on the other hand, is the slope of the line and represents the cost for each mile driven.
So the equation to represent this situation would be y = 2.50 + 1.10x where y is the total cost and x is the number of miles driven.
To find out how far you can travel with $10, you would set y to 10 and solve for x:
10 = 2.50 + 1.10x
To solve for x, subtract 2.50 from each side of the equation:
7.50 = 1.10x
Then divide each side by 1.10 to solve for x: x ≈ 6.82
So you could travel approximately 6.82 miles with $10.

34x - 18 = 10x - 9
solve for x
Hello there! Your answer would be x = 9/24.
You want to isolate x, and get everything on the other side of the equation.
Let's start by subtracting 10x from both sides. This will cancel it out on the right side, so our x values are only on the left side.
34x-10x - 18 = 10x-10x - 9
24x - 18 = - 9
Next, you want to add 18 to both sides so the x values are on their own side.
24x - 18+18 = - 9+18
24x = 9
Now our last step is to divide both sides by 24 to finish isolating x.
24/24x = 9/24
x = 9/24
The equation is already simplified, so we don't need to simplify any further. I hope this helps and have a great day!
The solution to the equation 34x - 18 = 10x - 9 is x = 3/8.
The given expression is,
34x - 18 = 10x - 9
Combining like terms.
We can do this by subtracting 10x from both sides, which gives us:
34x - 10x - 18 = -9
Simplifying further, we can combine the x terms:
24x - 18 = -9
Next, we'll add 18 to both sides of the equation:
24x = 9
Finally, we'll divide both sides by 24 to isolate x:
x = 9/24
Simplifying the fraction gives us:
x = 3/8
So the solution to the equation 34x - 18 = 10x - 9 is x = 3/8.

Jason makes $7 per hour picking up trash. His boss offers to pay him an additional $45 a week for sorting the recycling after work. What are the parameters in this scenario?
Answer:
The parameters are 7 and 45.
Step-by-step explanation:
Let's model the situation.
Let h be the number of hours Jason worked in a week.
Then, his total income is calculated as follows
His hourly charges = $7
Number of hours worked = h
So, hourly charges for the hours he worked = 7h
Additional income offered by his boss = 45
So, his total income per week = 7h + 45
Here, 7, the hourly charge and 45, the additional income are the parameters.

The value of n is both 5 times as much as the value of m and 36 more than the value of m. What are the values of n and m ? Explain.
Answer:
Values of n and m is; 45 and 9
Step-by-step explanation:
As per the given statement: The value of n is both 5 times as much as the value of m and 36 more than the value of m.
"value of n is 5 times as much as the value of m" means [tex]n = 5m[/tex]
"value of n is 36 more than the value of m" means [tex]n = 36 +m[/tex]
then we have an equation:
[tex]n = 5m[/tex] ......[1]
[tex]n = 36 +m[/tex] ......[2]
Substitute the value of n from equation [1] to [2] we get;
[tex]5m = 36 +m[/tex]
Subtract m from both sides we get;
5m -m = 36 + m -m
Simplify:
4m = 36
Divide both sides by 4 we get;
m = 9
Substitute the value of m=9 in equation [1];
n = 5(9)
n = 45
Therefore, the value of m = 9 and value of n =45
The value of n is 5 times the value of m and is also 36 more than the value of m. By solving two equations, we can find that the values of n and m are 45 and 9, respectively.
Explanation:The value of n is 5 times the value of m and is also 36 more than the value of m. Let's represent the value of m as x. According to the given information, we can write two equations:
n = 5m
n = m + 36
Now we can solve these equations to find the values of n and m. Substituting the value of n from the first equation into the second equation, we get:
5m = m + 36
Subtracting m from both sides of the equation:
4m = 36
Dividing both sides of the equation by 4:
m = 9
Plugging the value of m back into the first equation, we get:
n = 5(9) = 45
Therefore, the values of n and m are 45 and 9, respectively.

what is the value of x?
Answer:
x = 2
Step-by-step explanation:
When 2 secants are drawn from an external point to a circle the following theorem applies
outside × whole = outside × whole, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1) ← simplify
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand factors on both sides
x² + 13x + 12 = x² + 9x + 20 ( subtract x² from both sides )
13x + 12 = 9x + 20 ( subtract 9x from both sides )
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
