Write the standard form of the line that passes through the point (1, 5) and is parallel to the x-axis. Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
Answers
A horizontal line is represented by x = a number...with that number being the y coordinate of ur points. So ur parallel equation is : y = 5.....but we need it in standard form.....0x + y = 5
Answer:
Equation of line passing through the point (a,b) and having slope m is given by :
→ [tex]\frac{y-b}{x-a}=m[/tex]
Equation of X axis is , y = 0
i.e slope , m= 0
Any line parallel to x axis have slope = 0
Equation of line passing through the point (1,5) and parallel to X axis is given by :
→ y - 5 = m( x -1)
As , m=0
→ y -5 = 0× (x-1)
→ y- 5= 0
→ y = 5 [ Final Answer]

A taxi company charges passengers $1.00 for a ride, and an additional $0.30 for each mile traveled. The function rule C = 0.30m + 1.00 describes the relationship between the number of miles m and the total cost of the ride C. If the taxi company will only go a maximum of 40 miles, what is a reasonable graph of the function rule?
Answers
Answer: The graph of the function is shown below,
The given function is,
[tex]C=0.30m+1.00[/tex]
Where C is the cost and m is the distance in miles and it is a linear equation.
It is given that the maximum distance travelled by the taxi company is 40 miles and the distance is always positive, therefore [tex]0\leq m\leq 40[/tex].
The total cost of the company at initial distance means at m=0 is,
[tex]C=0.30(0)+1.00=1.00[/tex]
The total cost of the company at maximum distance means at m=40 point is,
[tex]C=0.30(40)+1.00=12.00+1.00=13.00[/tex]
So, [tex]1\leq C\leq 13[/tex].
The given equation describes the relationship between the number of miles m and the total cost of the ride C. The miles are independent variable and C is the dependent variable.
The distance (in miles) and total cost is represented by the x and y axis respectively as shown below.
The graph of the function C = 0.30m + 1.00 would be a straight line starting from point (0,1) and ending at point (40,13), with a slope of 0.30, reflecting the cost per mile and the initial flat rate.
Explanation:The function C = 0.30m + 1.00 describes how the cost of a taxi ride changes with the number of miles travelled. Here, 'C' represents the total cost (in dollars) and 'm' represents miles. The number 0.30 represents the cost per mile, and the 1.00 represents the initial cost regardless of distance traveled.
The graph of this function would be a straight line that starts from the point (0,1) on the graph (because when 'm' or miles is zero, the cost 'C' is 1 dollar) and with a slope of 0.30 (because for every mile, the cost increases by $0.30). Therefore, the line would go upwards and have a slope of 0.30. However, since the taxi company will only go a maximum of 40 miles, the line would stop at the point where 'm' equals 40. At 40 miles, the cost 'C' would be [tex]0.30*40 + 1 = $13.00.[/tex]

Write 8.25 × 103 as an ordinary number.
***** I need an explanation on how do you convert a standard from (without a power of 10) into a normal number.
** Brainliest, approved answer rewarded***
Answers
since ur exponent is positive, u move the decimal to the right...and since the exponent is 3, u move it 3 spaces to the right of ur decimal....8.25...moving the decimal 3 spaces to the right makes ur number 8250
examples :
2.3 * 10^5....move the decimal to the right 5 spaces, = 230000
5.67 * 10^4...move the decimal to the right 4 spaces, = 56700
now if ur number has a negative exponent, u would move ur decimal to the left.
2.3 * 10^-3....move ur decimal to the left 3 spaces, = 0.0023
5.467 * 10^-5....move the decimal 5 spaces to the left, = 0.00005467
Final answer:
To convert 8.25 × 10³ into an ordinary number, move the decimal point 3 places to the right, resulting in 8250. Similarly, for dividing powers of ten, subtract the exponents and divide the coefficients accordingly.
Explanation:
To convert 8.25 × 10³ to an ordinary number, you need to understand how powers of ten work in scientific notation. The exponent on the 10 indicates how many places to move the decimal point. Since the exponent is positive, you will move the decimal point to the right. For 8.25 × 10³, you move the decimal 3 places to the right, giving us 8250.
Now, addressing the division example of 2.4 × 10¹³ divided by 8 × 10⁷, we use the rule that when dividing powers of 10, we subtract the exponents. This gives us 10¹³/10⁷ = 10⁶ (13 minus 7 equals 6). Then we divide the coefficients (2.4 divided by 8 equals 0.3) to get the final answer of 0.3 × 10⁶, or 3 × 10⁵ when we adjust the coefficient to have a single digit before the decimal point.
what is the value f(-4)?
{-10 if x < -5
{x cubed if -5 less than or equal to x less than or equal to < 2
{2x + 4 if x > 2
a. -10
b. -12
c. -64
d. -4
Answers
-------------------------------------
-------------------------------------
This is a piecewise function. The function f(x) will change based on what x happens to be. There are 3 different cases here
Case A: f(x) = -10
Case A is only true if x < -5
Case B: f(x) = x^3
Case B is only true if -5 <= x <= 2
The symbol "<=" without quotes means "less than or equal to"
and finally,
Case C: f(x) = 2x+4
Case C is only true if x > 2
-------------------------------------
We want to find the value of f(-4) meaning we want to find the value of f(x) when x = -4
Look through the inequalities and see where x = -4 fits
does x = -4 make x < -5 true? In other words, is -4 smaller than -5? In other words is -4 to the left of -5? The answer to all of these questions is a simple "no"
So we move on. Check the second inequality -5 <= x <= 2 and sure enough -4 is between those two endpoints. So we'll use the second function
We will use f(x) = x^3
f(x) = x^3
f(-4) = (-4)^3 .... every x has been replaced with -4
f(-4) = (-4)*(-4)*(-4) ... expand out the cubic
f(-4) = ((-4)*(-4))*(-4)
f(-4) = (16)*(-4)
f(-4) = -64

Answers
Answer:
b
Step-by-step explanation:
The data set that matches the description best is Option C where both the median and the mean are 8, indicating a centrality of data around 8. This is the system, in other measures like range and mode, showing that if another measurement was taken, it would likely be around 8.
Explanation:The set of data described - data is around 8 and another measurement would also probably be around 8, can be best represented by Option C. In this option, the median is 8 and the mean is also 8. This signifies that the data is centered around 8 meaning, the typical value in the data set is around 8 and the average of all values is 8. If another measurement were to be taken at random, the most likely result would be close to this central value of 8.

What are the two numbers less than 20 with the most factors
Answers
They both have 6 factors.
Final answer:
The two numbers less than 20 with the most factors are 12 and 18, as each of them has six factors.
Explanation:
The question you're asking pertains to identifying the two numbers less than 20 that have the most factors. To find the numbers with the most factors, we list the number of factors for each number less than 20 and determine which have the most. Factors are the numbers you can multiply together to get another number. For example, 2 and 5 are factors of 10 because 2 x 5 = 10.
The number 12 has the factors 1, 2, 3, 4, 6, and 12, totaling 6 factors. On the other hand, the number 18 has the factors 1, 2, 3, 6, 9, and 18, also totaling 6 factors. Hence, the two numbers with the most factors less than 20 are 12 and 18, each with six factors.

You must multiply, subtract, and divide for this question:

15 * 2 = 30
75 - 30 = 45
45/3 = 15
