Helping in the name of Jesus.
Therefore, 4a + 12 - 2c + c = 25
Step-by-step explanation:a = 4
c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?
Answers
Answer:
We can start by using the formula:
time = distance / speed
Let t be the time (in hours) for Tom and Katherine to meet.
Tom's distance = Tom's speed x time = 14t
Katherine's distance = Katherine's speed x time = 10t
Since they are riding towards each other, the total distance they cover is the sum of their distances:
Tom's distance + Katherine's distance = 42 miles
14t + 10t = 42
Simplifying:
24t = 42
t = 42 / 24
t = 1.75 hours
Therefore, Tom and Katherine will meet after 1.75 hours of riding.

A recent conference had 650 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?
There were about 167 principals in attendance.
There were about 316 principals in attendance.
There were about 483 principals in attendance.
There were about 1,878 principals in attendance.
Answers
There were about 483 principals in attendance.
The correct option is (3).
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.
As per the given data:
The total number of people in the recent conference = 650
The total number of people in one exhibit room = 70
Number of teachers in one exhibit room = 18
Number of principals in one exhibit room = 52
To find out the total number of exhibit rooms:
= Total number of people in the conference / total people in one room
= 650 / 70
= 9.28 = 9 {rounding off to the nearest integer}
Number of principals in one exhibit room = 52
Total number of principals in the conference:
= Number of rooms × Principals in one room
= 9 × 52 = 468 which is equal to 483 {approximate answer}
There were about 483 principals in attendance.
Hence, There were about 483 principals in attendance.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Answer:
The x-intercept is (-5, 0).
The y-intercept is (0, 5).
Step-by-step explanation:
To find the x-intercept, we set y = 0 and solve for x:
0 = 5 + x
x = -5
Therefore, the x-intercept is (-5, 0).
To find the y-intercept, we set x = 0 and solve for y:
y = 5 + 0
y = 5
Therefore, the y-intercept is (0, 5).
Answer:
x-intercept is (-5,0)
y-intercept is (0,5)
Step-by-step explanation:
We are given a linear equation and are asked to find the x- and y-intercepts of the equation.
\(\Huge{y=5+x\)
\(\hrulefill\)
What are x- and y-intercepts?In mathematics, the terms "x-intercept" and "y-intercept" refer to points where a graph intersects the x-axis and y-axis. They are important concepts in the study of functions and graphs.
The x-intercept is the point at which a graph crosses or intersects the x-axis. It represents the value of x when y is equal to zero. In other words, it is the value of x when the function or equation is satisfied with y = 0. The x-intercept is often denoted as (x, 0), where "x" is the x-coordinate of the point.
Similarly, the y-intercept is the point at which a graph crosses or intersects the y-axis. It represents the value of y when x is equal to zero. Geometrically, it is the point on the graph where x = 0. The y-intercept is often denoted as (0, y), where "y" is the y-coordinate of the point.\(\hrulefill\)
(1) - Finding the x-intercept
To find the x-intercept, you set y equal to zero and solve the equation for x.
\(y=5+x\\\\\\\text{Let y=0}\\\\\\\Longrightarrow 0=5+x\\\\\\\Longrightarrow \boxed{x=-5}\)
Thus, the x-intercept is (-5,0).
(2) - Finding the y-intercept
To find the y-intercept, you set x equal to zero and solve the equation for y.
\(y=5+x\\\\\\\text{Let x=0}\\\\\\\Longrightarrow y=5+0\\\\\\\Longrightarrow \boxed{y=5}\)
Thus, the y-intercept is (0,5).\(\hrulefill\)
We can check this answer using a graphing calculator. Simply type in the given function and see were the function crosses each axis. Refer to the attached image.

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Sky High TV is a satellite television provider. They charged about a month. The first month of service costs 85.45. After the second month, the total cost is $148.65. After the third month, the total cost is $211.85. An equation in the form of y = c + d(x - 1) to represent the situation. Define the variables. ____________________________________________________________________________________________________________________________________________________________________________________________________________
Answers
Answer: y = 63.20x + 22.25, where x is the number of months and y is the total cost.
Step-by-step explanation:
Let's start by finding the value of the constant term c. We know that the first month of service costs $85.45, so we have:
y = c + d(x – 1)
85.45 = c + d(1 – 1)
85.45 = c
Now we need to find the value of the slope d. We can use the information from the second and third months:
y = c + d(x – 1)
148.65 = 85.45 + d(2 – 1)
63.20 = d
y = c + d(x – 1)
211.85 = 85.45 + d(3 – 1)
126.40 = 2d
Simplifying the second equation, we get:
63.20 = d
Substituting the values of c and d into the equation, we get:
y = 85.45 + 63.20(x – 1)
y = 63.20x + 22.25
Therefore, the equation that represents this situation is:
y = 63.20x + 22.25, where x is the number of months and y is the total cost.
