The line that passes through the given point and is parallel to the graph
y = -4x - 23.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Equation: y=-4x+3
As, we know that the slope of parallel line are same.
Now, using slope- intercept form
y = mx+ b
y = -4x+ b
Now, the line passes through (-4, -7).
So, y= -4x + b
-7 = -4(-4) + b
-7 = 16 + b
b = -23
So, the equation of parallel line is
y = -4x - 23

The probability that their meeting will be held at the station would be = 1/4
What is probability?Probability is defined as the representation of an expression which shows the possible outcome of an event.
The random time for the arrival of both friends at the station = ,7:20 - 7:00
= 20 minutes.
The extra minutes used to wait for each other which is outside the random time needed to arrive at the station = 5 min.
Therefore the probability for both of them meeting at the station = 5/20 = 1/4.

what is the slope of a line that has the coodinates of (10,23) & (20,36)?
Step-by-step explanation:
The slope of a line can be calculated as the difference of the y-coordinates divided by the difference of the x-coordinates of two points on that line. In this case, we have two points: (10,23) and (20,36).
So, the slope of the line would be:
(36 - 23) / (20 - 10) = 13 / 10 = 1.3.
Therefore, the slope of the line that has the coordinates of (10,23) and (20,36) is 1.3

Who will have traveled for a greater amount of time when their distance from New York stops decreasing and starts increasing?
A.
Charlie
B. They will have traveled the same amount of time.
C.
Annabeth
D. This cannot be determined from the given information.
The answer is B. Both Charlie and Annabeth will have travelled for the same amount of time.
They will have travelled the same amount of time. This is because the time spent traveling is determined by the total distance travelled, not the direction of travel. In this case, the distance between New York and the travellers' current location is decreasing at first and then increasing, suggesting that they have reached their destination and are now returning. Since the total distance travelled is the same regardless of the direction, the time spent traveling will also be the same for both travellers.

The new function obtained by performing f first and then g is the combination of two functions g and f.
The composition of two functions f and g, denoted by (f ◦ g)(x), is defined as the function that maps x to f(g(x)).
Given the functions f(x) = 2x + 3 and g(x) = -x^2 + 5, the composition of these two functions is:
(f ◦ g)(x) = f(g(x)) = f(-x^2 + 5) = 2(-x^2 + 5) + 3 = -2x^2 + 11

6.) Vanilla Ice takes out an ordinary loan to pay back a rental company. The bank has a 10.3% ordinary
interest rate for 240 days. What is the principal that Vanilla Ice borrowed if the result is a $330.00 interest
charge?
Let P be the principal Vanilla Ice borrowed. The interest charge is calculated as P * 10.3% * 240/365.
So, 330 = P * 10.3% * 240/365
Solving for P, we get:
P = 330 / (10.3% * 240/365) = $3,116.71
Therefore, Vanilla Ice borrowed a principal of $3,116.71.
Simple Interest (SI) is calculated based on the principal amount only, and the interest rate stays constant throughout the tenure. The formula for Simple Interest is:
SI = P * R * T
Where:
P = Principal amount
R = Interest rate
T = Time (in years)
Compound Interest (CI) is calculated based on the principal amount and the interest earned on it in previous periods. The interest earned in each period is added to the principal, and the new amount becomes the principal for the next period. This leads to an exponential growth of the invested amount. The formula for Compound Interest is:
CI = P * (1 + R/n)^(nt)
Where:
P = Principal amount
R = Interest rate
n = Number of compounding periods per year
t = Time (in years)
In summary, the main difference between simple and compound interest is that simple interest is calculated only on the principal amount, whereas compound interest is calculated on the principal amount and the accumulated interest.

The average of the 3-day simple moving averages for these five days to the nearest $0.01 is $105.99, $107.19 and $110.40.
What is a Simple Moving Average?
By dividing the number of periods inside the range by the average of the range of prices, simple moving averages are used.
We are given closing prices of a stock over a 5-day period.

What is domain and range?The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x).
A function's range is the collection of values it can take as input. The values in this set

The domain of the function is the input values, that is the x-coordinates thus,
Domain: -4 ≤ x ≤ 4
Range of the function is the output values, that is the y-coordinate thus,
Range: 0 ≤ y ≤ 3
Relative max is a point where the function changes from increasing to decreasing thus,
Relative max: x = 0, y=3
Relative min is a point where the function changes from decreasing to increasing, thus,
Relative min: x = -2, y=0 and x = 2, y =0
