Find the slope, y intercept and equation LAST ONE FOR THIS
Sara leaves home at 8:00 a.m. and drives at an average speed of 45 miles per hour. Her brother Pedro leaves home at 9:00 a.m. and drives along the same path at an average speed of 65 miles per hour. a. How many hours will Sara have driven when Pedro catches up with her? hours b. How far from home are they when Pedro catches up with Sara?
Using linear functions, we have that:
a. Sara will have driven 2.25 hours when Pedro catches up with her.
b. They are 146.25 miles from home when Pedro catches up with Sara.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.We have to consider the starting time as when Pedro leaves, when Sara will be at position 45 miles. Considering the velocities as the slope, the functions are:
S(t) = 45 + 45t. P(t) = 65t.Pedro will catch up with Sara when:
P(t) = S(t)
Hence:
65t = 45t + 45
20t = 45
t = 45/20
t = 2.25 hours.
Sara will have driven 2.25 hours when Pedro catches up with her.
The distance from home will be given by:
P(2.25) = S(2.25) = 65(2.25) = 45(2.25) + 45 = 146.25.
They are 146.25 miles from home when Pedro catches up with Sara.

Write a numerical expression for the difference of six and two divided by four
A local donut shop charges $0.89 per donut, plus a one-time charge of $0.15 for the box, the service, etc. (a) write a function that expresses the amount charged as a function of the number of donuts bought. (b) use the function from (a) to determine the price of a box with a dozen donuts in it. (c) use the function from (a) to determine how many donuts would in a box that cost $6.38.
The answers are as follows -
(a) f(x) = 0.15 + 0.89x
(b) $ 10.83.
(c) 7 donuts
(a) Firstly, forming the function using given information. Let x be the number of donuts. Adding the one-time fee and cost per donut.
f(x) = 0.15 + 0.89x
(b) As per the known fact, 1 dozen = 12 quantities. Hence, there will be 12 donuts. Keeping the values in formula to find the price of box.
f(12) = 0.15 + 0.89 × 12
f(12) = 0.15 + 10.68
f(12) = 10.83
Thus, the price of box containing one dozen donuts is 10.83.
(c) Now, finding the value of x as per given cost.
6.38 = 0.15 + 0.89x
0.89x = 6.38 - 0.15
0.89x = 6.23
x = 6.23 ÷ 0.89
x = 7
Thus, a box costing $6.38 will contain 7 donuts.
Hence, (a) f(x) = 0.15 + 0.89x, (b) $ 10.83 and (c) 7 donuts.

Factor completely using GCF
The factored expression of 21x^7y^7z^4 + 31x^4y^4 is x^4y^4(21x^3y^3z^4 + 31)
How to factor the expression completely?The expression is given as
21x^7y^7z^4 + 31x^4y^4
Express the above expression as a product
So, we have

Submit Answer
In Wednesday, the stock market had its biggest loss.
Over the course of a day, the stock market will fluctuate in value due to a number of factors. These include political news and economic data. Over the first four days of the week, this means that Monday through Thursday there is more volatility because these are typically the busiest trading days for stocks.
10.45 - (-18.75) = +29.2
-34.75 - (10.45) = -45.2
-40.89 - (-34.75) = -6.14
On Wednesday the stock value lost -45.2 of its value.
When the stock market loses value, it is usually because there are concerns about a company's future prospects. This can be due to changes in the business environment, new technologies that negatively impact the company's performance, or regulatory issues.
Hence, the stock market lost its most value on Wednesday .

Any straight line segment that cuts through the center of a circle and has ends that are on the circle is considered a circle's diameter in geometry. It is also known as the circle's longest chord.
Diameter also refers to the length d of a diameter. As opposed to a diameter, which refers to the line segment itself, one uses the term "diameter" in this context since all diameters of a circle or sphere have the same length, which is equal to twice the radius r. The longest distance that may be generated between the tangents of two opposite parallel lines is referred to as the diameter for a convex shape in the plane.

According to the given statement the first 13 words in this sequence add up to 260.
What is sequence?In mathematics, a sequence is an itemized group of elements where repeats are tolerated and order is significant. It has members, just like a set (also called elements, or terms). The length of the series is the number of items (potentially infinite). In contrast to a set, the same items might occur more than once in a sequence at various points, and unlike a set, the order is important. A sequence can be described formally as a function from natural numbers (the locations of the sequence's members) to the items at each of those positions. An indexed family, which is a function from an index set that may not be integers to another set of elements, can be thought of as a more extended version of a sequence.
According to the given data:We are informed that the order is2,5, 8, 11, ..... ..............(1)

If Samantha works in a department store selling clothing and she makes a guaranteed salary of $500 per week but is paid a commission on top of her base salary equal to 25% of her total sales for the week, then Samantha would make $662.5 in a week in which she made $650 in sales and she would make 500 + 0.25 xx in a week in which she made xx dollars in sales.
The amount of money Samantha makes in a week can be given by an algebraic expression.
Amount of money Samantha makes in a week = Salary per week + 25% of her total sale
Amount of money Samantha makes in a week = 500 + 0.25 x
Here x is the sales Samantha made in a week
If she made $650 in sales in a week :
Amount of money Samantha makes in a week = 500 + 0.25(650)

Find the slope of the line that passes through (-6,10) and (7,-10)
Take the difference in y coordinates and divide that by the difference in the x coordinates. That's the slope, sometimes called the "rise over run" For a straight line or a linear function the slope is a constant
(6-10)(7,10) = 2/3 = slope
the line is
y-h = m(x-k) where m=2/3 and (k,h) = (10,10) or either point
to get y-10 = (2/3)(x-10)
3y -30 = 2x-20
2x-3y = -10
or use (k,h) as (7,8)
y-8 = (2/3)(x-7)
3y-24 = 2x-14
2x-3y = -10
or if you write it in y=mx + b form
it's y=(2/3)x + 10/3 where 10/3 is the y-intercept and 2/3 = slope
In this form, take the derivative of (2/3)x + 10/3
to get y' = 2/3, the derivative is the slope

According to the given question.
Weigths of 10 young dogs.
W : 7, 5, 11, 8, 14, 19, 16, 15, 13, 27
As we know that mean si calculated by the formula
Mean = ΣW / n
Thereofre, the mean of the weights of 10 young dogs
= 7 + 5 + 11 + 8 + 14 + 19 + 16 + 15 + 13 + 27/ 10
= 13.5
And, Standard deviation (s) = 6.433
Proportion that lies in mean ± 2s
Lower = Mean - 2s
⇒ 13.5 - 2(6.433) = 0. 632
Also, Upper = Mean + 2s
⇒ 13.5 + 2(6.433) = 26.376
Mean ± 2(sd) = (0.632, 26.276)
The only digit from the data which falls outside the defined range = 27

When carpet sells for $4 per square foot and will cost you $616 to carpet your rectangular room, if you room is 14 feet long then the width is 11 feet
Given,
The cost of Carpet per square foot = $4
Total cost of the carpet = $616
We know
Area of the rectangle = Length × Width
Length = 14 feet
Consider the width of the rectangular room as x
Then the area of the room = 14x
Total cost of carpet = Area of the rectangular room× Cost of carpet per foot
Substitute the values
14x×4=616
14x=154
