Answer:
The total number of students at Milton Middle School is 240
I have some questions i need help with on my profile :)
Answer:
d. vertical line
Step-by-step explanation:
A line with an undefined slope is a vertical line
Slope is the change in y over the change in x
When the slope is undefined, it means that the x does not change, which is a vertical line
Question 2:
What are the factors of x² − 64?
let us first find square root of 64, which is 8
so writing x² − 64 as x² − 8²
Now we use the identity
a²-b² = (a+b)(a-b)
x²-8² = (x+8)(x-8)
So answer is option C. (x+8)(x-8)
Question 2:
Identify the factors of 4x² + 20x + 25.
Using AC method , we first multiply 4*25 =100
finding factors of 100 that add up to give 20 we have 10 and 10.
4x² + 10x+10x + 25
factoring by grouping we have,
(2x+5)(2x+5)
Option C is correct.
Question 3:
Determine the factors of 5x² + 29x − 6.
Using AC method, multiplying 5(-6) = -30, finding two factors of -30 that add up to give 29 are 30 and -1.
5x² + 30x-x − 6
factoring by grouping we get
(x+6)(5x-1)
option 1) is correct.
Question 4:
A polynomial function can be written as (x − 1)(x − 4)(x + 7). What are the x-intercepts of the graph of this function?
equating each product equal to zero,
(x-1) =0 , x=1
(x-4)=0, x=4
x+7=0, x=-7
so zeros are (1,0) , (4,0) and (-7,0).
Option C is correct.
The greatest common factor of 18 and 54 is 18
One way to determine the greatest common factor is to find all the
factors of the numbers and compare them.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.
The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the
greatest common factor is 18.
The greatest common factor can also be a calculated by identifying
the common prime factors and multiplying them together.
The prime factors of 18 are 2, 3, and 3.
The prime factors of 54 are 2, 3, 3, and 3.
The prime factors in common are 2, 3, and 3, so the greatest common
factor is 2 x 3 x 3 = 18.
hope this help
Answer:
the right side of the image is truncated,
but "A" seems to be the answer....
take (2,3) and (3,4)
#1) y2-y2/x2-x1 ... 4-3/3-2 = 1 ... slope = 1
#2 ) y = 1x + b
#3 plug in (2,3) ... 3 = 1(2) + b ... B=1
#4 Y= 1 x + 1
