The graph of a function contains the points (6, 7) and (10, 13). Which of these statements is correct based on this information?
A. If the graph also contains the point (4, 4) then the function must not be linear.
B. If the graph also contains the point (12, 16) then the function must not be linear.
C. If the graph also contains the point (1, 2) then the function could be linear.
D. If the graph also contains the point (8, 10) then the function could be linear.
Answer:
The true statements are:
B and D.
Step-by-step explanation:
First, a linear function can be written as:
y = a*x + b
Such that a is the slope, and b is the y-intercept.
If we know that the graph of the function passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we have a function that passes through the points (6, 7) and (10, 13), then if this function is linear, the slope is:
a = (13 - 7)/(10 - 6) = 6/4 = 3/2
Then the function will be something like:
f(x) = (3/2)*x + b
Knowing that the function passes through (6, 7), this means that:
f(6) = 7
Then:
(3/2)*6 + b = 7
3*3 + b = 7
9 + b = 7
b = 7 - 9 = -2
The function, if linear, is:
f(x) = (3/2)*x - 2
Now let's read the statements:
A) If the graph also contains the point (4, 4) then the function must not be linear.
If the point is a solution of the equation, then the function is linear.
If the point is not a solution of the equation, then the function is not linear.
f(4) = 4 = (3/2)*4 - 2
4 = 3*2 - 2
4 = 6 - 2 = 4
Then (4, 4) is a solution, so if the graph also contains the point (4, 4) the function can be linear. Then the statement "A" is false.
Now let's do the same analysis for the other statements:
B) If the graph also contains the point (12, 16) then the function must not be linear.
F(12) = 6 = (3/2)*12 - 2 = 3*6 - 2 = 18 - 2 = 16
6 = 16
(12, 16) is not a solution, so if the graph contains this point, the function is not a linear function, the statement is true.
C) If the graph also contains the point (1, 2) then the function could be linear.
f(1) = 2 = (3/2)*1 - 2 = 3/2 - 2 = -1/2
The point (1, 2) is not a solution, so if the graph contains this point, then the function can't be linear, so the statement is false.
D) If the graph also contains the point (8, 10) then the function could be linear.
f(8) = 10 = (3/2)*8 - 2
10 = 3*4 - 2 = 12 - 2
10 = 10
The point (8, 10) is a solution of the linear equation, so if the graph contains this point, the function could be linear, so the statement is true.

Answer:
3
Step-by-step explanation:
y = -3x^2 + 5x + 3
↑ this is "the number at the end/constant," and according to the question the number at the end/constant is the y-intercept
Thus, the y-intercept is 3.

A new school is ordering math textbooks. They are 3/4 of an inch thick. How many of these books will fit into a bookshelf that is 2 feet long?
A) 2 books
B) 12 books
C) 26 books
D) 32 books
Answer:
32 Books
Step-by-step explanation:
You know that the bookshelf is 2 feet long, and you know the book is 3/4 inches thick. To start you have to get a common measurement in this case we will use inches. You already know that 1 foot is 12 inches so 2 feet will be 24 inches. Next all you do is divide the 24 inches by 3/4 inches. This will give you 32 which is the total amount of books that can fit on the bookshelf.
Jim's basketball team scores 97 points
in a game. The team made a total of 41
two-point and three-point baskets. How
many of each type of basket did the
team make?
A 15 two-pointers and
26 three-pointers
B 18 two-pointers and
23 three-pointers
C 23 two-pointers and
18 three-pointers
D 26 two-pointers and
15 three-pointers
Answer:
D) 26 two-pointers and 15 three-pointers
Step-by-step explanation:
x= 2 pointers
y= 3 pointers
Make a system of equations:
x=41-y
2x+3y=97
Plug In:
2(41-y)+3y=97
82+y=97
y= 15 (three point shots)
Check:
15(3)=45
97-45=52
52/2=26
x=26 (2 point shots)
HURRY! What value of m completed the two-way table?
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
Answer:
A - 13
Step-by-step explanation:
50 (8th graders) - 8 (tiling lovers) - 29 (carpeting lovers) = 13 (wooden floor lovers)

Number of miles a car travels are 28.
What is division?The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Number of gallons of gas = 20
A car with 20 gallons of gas can drive 560 miles
Based on the given conditions,
= [tex]\frac{560}{20}[/tex]
= 28
Hence, number of miles are 28.

In a game, students draw a card, replace it, and then draw again. What is the probability of drawing a prime number then a composite number
Answer:
16 / 81
Step-by-step explanation:
Between digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9
Prob (prime number) = Prime numbers / Total numbers ; Prime numbers = 1,3,5,7. So, Prob = 4 / 9
Prob (composite number) = Composite numbers / Total numbers ; Composite numbers = 2, 4, 6 , 8. So, Prob = 4 / 9
Prob (Prime & Composite) = 4 / 9 x 4 / 9 = 16 / 81

Step-by-step explanation:
comment if u need explanation :))
Answer:
3 x 3 x 3 = 27
2 x 2 = 4
27 + 4 = 31, the answer is C
Since it is exponents
3 to the power of three means you multiply three by itself 3 times which equals 27.
Same with 2 to the power of 2,
you multiply 2 by itself 2 times therefore you get 4 and add them up to get 31.

Answer:
184 cm^2
Step-by-step explanation:
To find the surface area, find the area of each of the faces and add them up.
Let's start with the base/bottom.
The dimensions are 6 and 10, and it is a rectangle.
Area = 6 x 10 = 60 cm^2
Next, lets do the slanted sides.
The dimensions are 10 and 5, and they are both rectangles.
Area = 10 x 5 = 50 cm^2
Since there are 2 of the slanted sides, multiply 50 by 2.
50 x 2 = 100 cm^2
Then, do the triangles.
The dimensions are 6 (base) and 4 (height)
Area = 6 x 4 / 2
Area = 24 / 2
Since there are 2 triangles, we do not need to divide by 2. We will need to multiply by 2 afterwards, so there's no point in dividing by 2.
24 cm^2
Finally, add up all the areas.
60 + 100 + 24 = 184 cm^2
Heh, funny, there's no answer choice for that... maybe ask your teacher?
