Step-by-step explanation:
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
ANALYZING TABLE 1
Part A)
Given table 1
x 0 1 2 3
y 1 3 5 7
From table 1, the y-intercept can be determined by setting x=0 and checking the corresponding y-value.
so at x = 0, y = 1
Thus, the y-intercept is (0, 1).
From the graph, it is clear that the line W has a y-intercept (0, 1).
Therefore, table 1 represents the line W.
Part B)
Taking two points (0, 1) and (1, 3) to find the slope using the formula
m = (y₂-y₁) / (x₂-x₁)
m = 3-1 / 1-0 = 2/1 = 2
now substituting m = 2, and b = 1 in the slope-intercept form
y = mx+b
y = 2x+1
Thus, table 1 represents the line W with the equation line y = 2x+1
ANALYZING TABLE 2
Part A)
Given table 2
x 0 1 2 3
y 0 3 6 9
From table 2, the y-intercept can be determined by setting x=0 and checking the corresponding y-value.
so at x = 0, y = 0
Thus, the y-intercept (0, 0).
From the graph, it is clear that line F has a y-intercept (0, 0).
Therefore, table 2 represents the line F.
Part B)
Taking two points (0, 0) and (1, 3) to find the slope using the formula
m = (y₂-y₁) / (x₂-x₁)
m = 3-0 / 1-0 = 3/1 = 3
now substituting m = 3, and b = 0 in the slope-intercept form
y = mx+b
y = 3x+0
y = 3x
Thus, table 2 represents the line F with the equation y = 3x
ANALYZING TABLE 3
Part A)
Given table 1
x 0 1 2 3
y 2 3 4 5
From table 3, the y-intercept can be determined by setting x=0 and checking the corresponding y-value.
so at x = 0, y = 0
Thus, the y-intercept (0, 2).
From the graph, it is clear that line N has a y-intercept (0, 2).
Therefore, table 3 represents line N.
Part B)
Taking two points (0, 2) and (1, 3) to find the slope using the formula
m = (y₂-y₁) / (x₂-x₁)
m = 3-2 / 1-0 = 1/1 = 1
now substituting m = 1, and b = 2 in the slope-intercept form
y = mx+b
y = (1)x+2
y = x+2
Thus, table 2 represents the line N with the equation y = x+2

Answers
Answer: 0.2d
Step-by-step explanation: For calculating the 20% tip of the cost in dollars of a dinner, simply multiply 0.2 by the cost of dollars of a dinner. 0.2 represents 20% and by using the variable "d" to represent the cost of the dinner, you can write this equation: 0.2d.

Simplify the following expression.
?
9t2 + 7t + 4 - 2t2 + 5t
Answers
Answer:
I'm assuming the 2 after 9t and -2t means squared.
7t² + 12t + 4
Step-by-step explanation:
To simplify the expression we should combine like terms. Like terms are terms with same variables and powers.
Let's start with 9t² and -2t² since they have the same variable and power of t². To combine them we should add them together which would be: 9t² + (-2t²) = 9t² - 2t² = 7t²
Next we can combine 7t and 5t since they have the same variable and power of t. 7t + 5t = 12t
4 doesn't have any like terms so we leave it as it is.
Lastly we add all of our terms: 7t² + 12t + 4

Find three consecutive POSITIVE ODD integers such that when you multiply the first
and third the result is nine less than six times the second integer.
Answers
Answer:
3, 5, 7
Step-by-step explanation:
Let the first of the three positive consecutive odd numbers be [tex]x[/tex].
Now, the second odd number = [tex]x+2\\[/tex]
And, the third odd number = [tex]x+4[/tex]
As per question statement, the multiplication of the first and third odd number is 9 lesser than the 6 times the second integer.
Writing the equation, we get:
[tex]x(x+4) = 6(x+2)-9\\\Rightarrow x^{2} +4x=6x+12-9\\\Rightarrow x^{2} +4x-6x = 3\\\Rightarrow x^{2} -2x - 3=0\\\text{Solving the above equation by factorization method:}\\\Rightarrow x^{2} -3x +x - 3=0\\\Rightarrow x(x -3) + 1(x - 3)=0\\\Rightarrow (x -3) (x+ 1)=0\\\Rightarrow x =3, -1[/tex]
As, we got a quadratic equation, so we have two solutions here.
One is positive integer and other one is negative.
So, solution is [tex]x=3[/tex]
First number is 3.
Second number is 3 + 2 = 5
Third number is 5 + 2 = 7

guys help I am stuck on this question I have to send my winter holiday
48 girls and 64 boys belong to the Twelve Mile Coulee School choir. The choir teacher plans to arrange the students into equal rows (the same number of students in each row). Only girls or boys will be in each row. What is the greatest number of students that could be in each row?
Answers
Answer:
16
Step-by-step explanation:
To find the greatest number of students that could be in each row, we need to find their greatest common factor. We can list out their prime factors first.
48: 2 × 2 × 2 × 2 × 3
64: 2 × 2 × 2 × 2 × 2 × 2
Here, their common prime factors are 2 × 2 × 2 × 2 which is 16. Thus, the greatest number of students that could be in each row is 16.
No. of rows in the girls = 48 ÷ 16
= 3
No. of rows in the boys = 64 ÷ 16
= 4
Answer:
Step-by-step explanation:
I believe for this question you need to find the HCF (or GCF you may say) of 48 and 64
HCF - Highest Common Factor
GCF - Greatest common Factor
First, prime factorize 48 and 64 (write them in the product of their prime numbers)
64 = 2 × 2 × 2 × 2 × 2 × 2
48 = 2 × 2 × 2 × 2 × 3
Choose common prime factors (all of them that are common)
on observation, there is 2 × 2 × 2 × 2 common between both of them
which is 16.
So 16 maximum people in each row
Also additional thing, it's fine if some questions were wrong, try and attempt it yourself first before asking it from someone. Getting used to ask someone is going to be troublesome in the long run. If you get stuck, then get help from your teachers (unless the teacher is unco-operative) in which case, seek help from your friends, or talk to your parents about it if you freely share stuff with them.
But anyway, hope that helps ^

Explain how you know that segment de is not parallel to segment bc
Answers
Line segments DE and BC are not parallel because they divide the opposite side of the triangle at different ratios.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
Given, Line segment AD is 4 units and line segment DB is 2 units.
∴ Line segment AD is (4/2) = 2 times greater.
On the other hand line segment, AE is 9 units and line segment EC is 5 units.
∴ Line segment AE is (9/5) = 1.8 times greater.
Line segments BC and DE should have been parallel if they had the same ratios.

The pencils produced by the machine are unsharpened, so two employees in the factory need to sharpen each pencil by hand. Employee A can sharpen 8 pencils per minute and Employee B can sharpen 5 pencils per minute. Employee A breaks 10% of the pencils they sharpen and Employee B breaks 15% of the pencils they sharpen. What is the probability that a broken pencil was broken by Employee A
Answers
Answer:
0.4156
Step-by-step explanation:
Given that:
Employer A:
8 pencils per minute
Probability of breaking a pencil = p(A) = 10%
Employer B:
5 pencils per minute
Probability of breaking a pencil = p(B) = 15%
Hence,
Probability of breaking a pencil:
P(breaking a pencil) = (P(A breaks pencil) * P(A)) + (p(B breaks pencil) * p(B))
P(A breaks pencil) = 0.1 * 8 = 0.8
P(B breaks pencil) = 0.15 * 5 = 0.75
P(breaking a pencil) = (0.8 * 0.1) + (0.75 * 0.15) = 0.1925
Hence, probability that a broken pencil was broken by employer A will be :
(P(A breaks pencil) * P(A)) / probability of breaking a pencil
= (0.8 * 0.1) / 0.1925
= 0.08 / 0.1925
= 0.4155844
= 0.4156

Answer:
Equation: x° + x° + (x + 10)° + 59° = 360°
Solution: x = 97
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Therefore:
x° + x° + (x + 10)° + 59° = 360°
Solve for x
x + x + x + 10 + 59 = 360
Add like terms
3x + 69 = 360
Subtract 69 from each side
3x = 360 - 69
3x = 291
Divide both sides by 3
x = 97
What is the rate change of the linear function that has a graph that passes through the points (2,9) (-1,3)
Answers
(3-9)/(-1-2) = -6/-3 = 2
The rate of change is 2
The linear function is y = 3x + 6. Then the rate of change of the linear function will be 3.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
The linear equation that is passing through the points (2,9) and (-1,3).
Then we have
y - 3 = [(3 - 9)(-1 - 2)] (x + 1)
y - 3 = (-6) / (-2) (x + 1)
y - 3 = 3x + 3
y = 3x + 6
Then the rate of change of the linear function will be
y' = 3

Answers
Answer:
48
Step-by-step explanation:
Hi!
Remember, the sum of the angles on a straight angle is 180 degrees. Additionally, the sum of the measures of a triangle are 180 degrees.
Now, let's label the angles of the given triangle.
<DCE = y and <CDE=x
x+y+92=180
x+y= 88
Now, y+140 = 180 --> y= 40
x+40 = 88
x=48
The answer is 48 degrees.
Hope this is correct! Have a good day!
