A mountain climber records her altitude and the surrounding temperature at various points as she ascends a mountain. She then plots the points on a scatter plot and draws a line of best fit. The equation of the line is y=−3.6x+59 , where x is the altitude in thousands of feet and y is the temperature in degrees Fahrenheit (°F). What does the slope of the equation represent in this scenario?
Answer:
-3.6
Step-by-step explanation:
The general equation of a straight line formula is represented as y = mx + c, where m is the gradient or slope of the line and c is called the intercept on the y-axis.
The equation of the line in the question above is y= −3.6x + 59 ,
Therefore comparing both equations together,
y = mx + c = y = −3.6x + 59
m = -3.6
Therefore, the slope of the equation represent in this scenario is -3.6
Let f(x)=3x2+2x−3. What is f(3)?

Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 3x² + 2x - 3
f(3) is x = 3
Step 2: Evaluate
Substitute in x: f(3) = 3(3)² + 2(3) - 3Exponents: f(3) = 3(9) + 2(3) - 3Multiply: f(3) = 27 + 6 - 3Add: f(3) = 33 - 3Subtract: f(3) = 30The mean number of independent-reading books read by the 4 eighth-grade students shown in the scatterplot is the same as the mean number of independent-reading books read by all 62 eighth-grade students in the school last year.

9x + 5 = 86
Answer: 9(9)+ 5 = 86
Step-by-step explanation: the x equals 9 so means 9(9) + 5 = 86
Answer:
x = 9
Step-by-step explanation:
9x + 5 = 86, minus 5 of both sides
9x = 81, divide 9 on both sides
x = 9
The algebraic expression p(x) = 3x^4 +1 can become a polynomial:
a) for any value of a, b and c
b) a + b=c
c) b=0
d) b=√2
Answer:
A polynomial p(x) in one variable x is a mathematical articulation in x of the structure p(x) = anx n + an−1x n−1 + ....... + a2x 2 + a1 x + a0, where a0, a1, a2, .... an are individually the coefficients of x 0 , x 1 , x 2 , .... x n and n is known as the level of the polynomial if a ≠ 0. Each anx n ; an−1x n−1 ; .... a0, is known as a term of the polynomial p(x)

Landon is building new bookshelves for his bookstore's new mystery section. Each shelf can hold 37 books. There are 1,221 mystery books. How many shelves will he need to build? (please help I suck at mathhhh!)
Answer:
33
Step-by-step explanation:
Landon is building new book shelves for his bookstore's new mystery section
Each of the shelf can hold 37 books
There are 1221 mystery books
Therefore the number of shelves that Landon will need to build can be calculated as follows
= 1221/37
= 33
Hence Landon needs to build 33 shelves

*4. On Saturday, a minor league baseball team gave away baseball cards to each person entering the stadium. One group received 28 baseball cards. A second group received 68 baseball cards. If each person entering the stadium received the same number of cards, what was the greatest number of baseball cards that each person could have received?
9514 1404 393
Answer:
4
Step-by-step explanation:
The greatest common factor of 28 and 68 is 4.
28 = 4×7
68 = 4×17
Each person could have received 4 baseball cards.

HELP DUE AT 11:59!
Answer:
a₇ = [tex]\frac{4096}{3125}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 4 ÷ 5 = [tex]\frac{4}{5}[/tex]
r = [tex]\frac{16}{5}[/tex] ÷ 4 = [tex]\frac{4}{5}[/tex]
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = [tex]\frac{4}{5}[/tex] , thus
a₇ = 5 × [tex](\frac{4}{5}) ^{6}[/tex] = 5 × [tex]\frac{4096}{15625}[/tex] = [tex]\frac{4096}{3125}[/tex]

Solve the following system of inequalities graphically on the set of axes below. State the coordinates of a point in the solution set.
(PLEASE HELP!!!)
The solution to the system of inequalities y < 2x - 8 and y > -1/2x - 3 is (2, -4)
How to solve the system of inequalities graphically?The system of inequalities is given as
y < 2x - 8
y > -1/2x - 3
Next, we plot the system of inequalities on a graph (see attachment)
From the attached graph, we have both lines of the graph intersect at (2, -4)
Hence, the solution to the system of inequalities y < 2x - 8 and y > -1/2x - 3 is (2, -4)

Answer: Left-brace 14, negative 7, 0, 243, negative 3 Right-brace
Step-by-step explanation:
To obtain our answer, we need to know what an integer means and hence, it's properties or characteristics ;
An integer must be an whole number including Zero, which means no fractions
Similarly, integer numbers could be either positive or negative in value.
Hence, from the set represented above ;
(14, - 7, 0, 243, - 3) ; all the numbers in the set conform to the characteristics expected of an integer.

Sarah buys a package of 500 jewelry to decorate for different pairs of jeans she uses the same number of Jewelry each pair of jeans how many jewelry well she use for each pair of jeans
When Sarah buys a package of 500 jewelry to decorate four different pairs of jeans, the number of jewelry fur each pair is 125 jewelries.
How to illustrate the information?It should be noted that Sarah buys a package of 500 jewelry to decorate 4 different pairs of jeans and it was stated that she uses the same number of Jewelry each pair of jeans.
Therefore, it should be noted that the number of jewelry that she will use for each pair of jeans will be:
= Number of jewelry / Number of jeans
= 500 / 4.
= 125
Therefore, when Sarah buys a package of 500 jewelry to decorate four different pairs of jeans, the number of jewelry fur each pair is 125 jewelries.

because both sides are like that 48×2=96 for the middle 12-9=3 I did that because I needed to know the sides of this new rectangle so now 3×6=18 now we need to add them together to get the area 48+96+18=162
