Hello,
I hope you and your family are doing well!
The answer is y = 5 (See below for the explanation).
To find a linear equation representing a line passing through two points, you can use the slope-intercept form of the equation, which is written as y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To find the slope of the line, you can use the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two given points, we get:
m = (5 - 5) / (-8 - 3) = 0 / -11 = 0
Since the slope of the line is 0, the line is horizontal and passes through both points at the same y-value (5). The x-intercept (the point at which the line crosses the x-axis) is not relevant in this case.
Therefore, the linear equation representing this line is y = 5.
Happy Holiday & New Year!

If a polynomial f(x) has a remainder of 4 when divided by x-5, what is f(5)?
The remainder of 4 when f(x) is divided by x - 5 means that f(5) = 4
How to determine the remainder of the quotientFrom the question, we have the following parameters that can be used in our computation:
The function is given as
Polynomial = f(x)
Remainder = 4
The function is represented as
z(x)
This means that
x = 5 in f(x)
So, we add -5 to both sides of the equation
This gives
x - 5 = 0
Also, we have
A remainder of 4 when divided by x-5
So, when the equation in interpreted, it means
The remainder when f(x) is divided by x - 5 is 4

over time v(t) can be modeled by the following formula:
1.36(0.9758)', where t is the number of years since 2000.
0.9758 is the decay factor of the model
How to determine the decay factor?Given that:
The value of the U.S. dollar over time v(t) can be modeled by the following formula:
v(t) = 1.36(0.9758)^t , where t is the number of years since 2000
The form of the exponential decay models is f(t) = ab^t
where,
a is the initial value, b is the decay factor and t is the time
Comparing f(t) = ab^t with v(t) = 1.36(0.9758)^t :
a = 1.36
b = 0.9758

The solutions to the x and w variables are x = 2097153 and w = (6)⁻²/⁵
How to determine the solution to the variables?From the question, we have the following parameters that can be used in our computation:
1/7log(x - 1) = 3log(2)
3 ln(w + 6) = 5 ln(6)
Solving the equation (1), we have the following equation
1/7log(x - 1) = 3log(2)
Multiply both sides of the equation by 7
So, we have the following representation
log(x - 1) = 21log(2)
Apply the power rule of logarithm
log(x - 1) = log(2)²¹
By comparison, we have
x - 1 = (2)²¹
Evaluate the exponent
x - 1 = 2097152
So, we have
x = 2097153
Solving the equation (2), we have the following equation
3 ln(w + 6) = 5 ln(6)
Multiply both sides of the equation by 1/3
So, we have the following representation
ln(w + 6) = 5/3 ln(6)
Apply the power rule of logarithm
ln(w + 6) = ln(6)³/⁵
By comparison, we have
w + 6 = (6)³/⁵
So, we have
w = (6)⁻²/⁵
Hence, the solutions are x = 2097153 and w = (6)⁻²/⁵

In the fall of 1996, tuition and registration fees for undergraduates at the University of California, Davis was $1411. In the fall of 2018, tuition and fees
were $14,402. Find the percent increase. Round your answer to the nearest tenth percent
% increase
To find the percent increase, we need to calculate the difference between the new tuition and fees and the old tuition and fees, and then divide this difference by the old tuition and fees and multiply by 100%.
The difference between the new tuition and fees of $14,402 and the old tuition and fees of $1411 is $14,402 - $1411 = $12,991.
The percent increase is: ($12,991/$1411) * 100% = 9.2 * 100% = 920%
Therefore, the percent increase in tuition and fees between the fall of 1996 and the fall of 2018 was 920%, rounded to the nearest tenth percent.

What do you mean by congruent?When it comes to geometry, two figures or objects are said to be congruent if they are the same size and shape, or if one is the mirror image of the other.
More specifically, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid motions including translation, rotation, and reflection. This indicates that either object may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. If we can cut out and then perfectly match up two separate plane figures on a piece of paper, they are then congruent. I'm allowed to turn the paper over.
Here both the given figures are congruent figures. So, their shape and size must be equal.
Therefore from the two figures, PM=DA
So, PM=6

the equation of the normal to the 2x² + 2y² -4x +4y =12 at the point (-1,1) is
To find the equation of the normal to the given curve at the point (-1,1), you can use the following steps:
Rewrite the given equation in the form "y = mx + b," where m is the slope of the curve and b is the y-intercept.
Find the slope of the curve at the point (-1,1). This can be done by taking the derivative of the equation and evaluating it at x = -1.
The slope of the normal line at the point (-1,1) is the negative reciprocal of the slope of the curve at that point. Calculate this value.
Use the point-slope formula to write the equation of the normal line in the form "y - y1 = m(x - x1)," where (x1, y1) is the point (-1,1) and m is the slope of the normal line.
Substitute the values for x1, y1, and m into the point-slope formula to obtain the final equation of the normal line.
For example, if the given equation is 2x^2 + 2y^2 - 4x + 4y = 12, you can follow these steps:
Rewriting the equation in slope-intercept form, we get: y = -x + 2
Taking the derivative of the equation, we get: y' = -1
The slope of the normal line is the negative reciprocal of the slope of the curve, which is 1/-1 = -1
Using the point-slope formula, we get: y - 1 = -1(x + 1)
Substituting the values into the point-slope formula, we get: y - 1 = -1x - 1
Thus, the equation of the normal line at the point (-1,1) is y - 1 = -1x - 1.
At the end of a snowstorm, Gabriella had 11 inches of snow on her lawn. The

inches per hour. Assuming no more snow was falling, how much snow would
Gabriella have on her lawn 3 hours after the snow began to melt? How much snow
would Gabriella have on her lawn after t hours of snow melting?
The snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t
What is a constant rate of change?
A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Constant rate is also called uniform rate which involves something traveling at a fixed and steady pace or else moving at some average speed.
The snow started melting at a rate of 0.5 inches per hour and it is known that 3 hours after the storm ended, the depth of snow was down to 11 inches.
Snow melted in 3 hours = 0.5 * 3 = 1.5 inches
Thus;
The Initial depth of snow = 11 + 1.5 inches = 12.5 inches.
Now, depth of snow on Gabriella's lawn = Initial depth - 0.5(Number of hours)
Let S(t) be the depth of snow on Gabriella's lawn, in inches, t hours after the snow stopped falling.
Hence, the snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t

Let 3x = the number of green marbles and 4x = the number of red marbles
By using the ratios and the total we can know how many green and red marbles are there in a bag. so the formula is:
ax+bx=t-------(1)
a and b are ratios of given marbles
t is the total number of marbles
x is to find the value

A local company offers you an opportunity to sell discount cards. You will have to pay the company a one-time setup fee of $320. Each card will cost you $6. How many cards would you have to sell before your average total cost per card falls to $10?
Answer:
80 cards would have to sold before your average total cost per card falls to $10
Step-by-step explanation:
To find the number of cards you would have to sell to bring the average total cost per card down to $10, you can use the following formula:
number of cards = setup fee / (average total cost per card - cost per card)
Plugging in the values given in the problem, we get:
number of cards = $320 / ($10 - $6)
Solving this equation gives us:
number of cards = $320 / $4
Dividing 320 by 4 gives us a result of 80, so you would have to sell 80 cards before your average total cost per card falls to $10
Another approach is setting it up as y = mx+b
$10 = (320 + 6x) / x
Where x is the number of cards that you need to sell.
Solving for x, we get:
$10x = 320 + 6x
4x = 320
x = 80
