Answer: A
Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added or subtracted.
Notice that in the the first sequence shown, we add 4 to reach the next term in the sequence which means this is arithmetic.
The others are not arithmetic because the difference
between the terms does not remain constant.

The only pair of possible values for x and y is (1,3) that satisfies the inequality expression.
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal.
For the given situation,
The expression is
x and y are integers, y>2, x<2
y< x + 3
[tex]x < 2[/tex] , x can take any value less than two.
⇒ [tex]x=1[/tex] and
[tex]y > 2[/tex] , y can take any value greater than two
⇒ [tex]y=3[/tex]
Thus the expression becomes,
⇒ [tex]y < x + 3[/tex]
⇒ [tex]3 < 1 + 3[/tex]
⇒ [tex]3 < 4[/tex]
Hence we can conclude that the only pair of possible values for x and y is (1,3) that satisfies the inequality expression.

Answer:
3: x = 3 4: y = 8
Step-by-step explanation:
Problem 3:
Because of the lines on each side of the rhombus, that shows you that all of those lines are congruent with each other, meaning they are all the same length. So since one side equals the other, you can equal one of the equations on one side to another equation on another side. EX: x+5 = 3x-1. And then you solve that through multi-step equations.
Problem 4:
Just like on Problem 3, due to the little dashes going through the sides of the rectangle, the sides are congruent (the same length) as one another. Except the sides with one dash are not congruent with the sides with two dashes. But if you equal 2y and y+8, then you can solve that through multi-step equations again and get y = 8 since they are congruent with each other (due to the singular dashes running through their sides).
Hope this helped!

A rectangular room is 2 times as long as it is wide, and its perimeter is 36 meters. Find the width of the room.
The width of the room is equal to 6 m
What is the area of the rectangle?The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.
Given here: Perimeter=36 m
Let the length of the room be 2x and width of the room be x
Then we have (2x+x)=36
x=12
Thus length =12m & width=6 m
Hence, the width of the room is equal to 6 m

Step-by-step explanation:
What are the coordinates of point P on the directed line segment from A to B such that P is One-fourth the length of the line segment from A to B? (StartFraction negative 29 Over 4 EndFraction , negative three-halves) (negative thirteen-fourths, one-half) (negative eleven-fourths, negative one-half) (twenty-five-fourths, negative one-half)
Answer:
Option C is the correct answer.
Step-by-step explanation:
Given:
The coordinates of the point A and B are (-5,-1) and (4,1)
The point P on the directed line segment from A to B such that P is One-fourth the length of the line segment from A to B.
Thus, we have;
m=1 and m+n=4
We need to determine the coordinates of the point P(x,y)
x - coordinates of the point P:
The x - coordinates of the point P can be determined using the formula
x=(m/m+n)(x₂ - x₁)+ x₁
Substituting the values, we get;
x= 1/4(4+5)-5
x = 9/4-5
x = -11/4
Thus, the x - coordinate of the point P is -11/4
y - coordinate of the point P:
The y - coordinate of the point P can be determined using the formula,
y=(m/m+n)(y₂ - y₁)+ y₁
Substituting the values, we get;
y= 1/4(1+1)-1
y = 2/4-1
y= -2/4
y= -1/2
Thus, the y - coordinate of the point P is -1/2
Therefore, the coordinates of the point P is (-11/4, -1/2)
Hence, Option C is the correct answer.

f(x) = -4x2 + 12x – 9
What is the value of the discriminant of f?
How many x-intercepts does the graph of f have?
Answer:
[tex]D = 0[/tex]
The graph has 1 x-intercept
Step-by-step explanation:
Given
[tex]f(x) = -4x^2 + 12x - 9[/tex]
Required
- Discriminant of f
- Number of x intercepts
Let D represent the discriminant;
D is calculated as thus
[tex]D = b^2 - 4ac[/tex]
Where a, b and c are derived from the following general format;
[tex]f(x) = ax^2 + bx +c[/tex]
By comparing [tex]f(x) = ax^2 + bx +c[/tex] with [tex]f(x) = -4x^2 + 12x - 9[/tex]
We have
[tex]f(x) = f(x)\\ax^2 = -4x^2\\bx = 12x\\c = -9[/tex]
Solving further;
[tex]a = -4\\b=12\\c=-9[/tex]
So, D can now be calculated;
[tex]D = b^2 - 4ac[/tex] becomes
[tex]D = 12^2 - 4 * -4 * -9[/tex]
[tex]D = 144 - 144[/tex]
[tex]D = 0[/tex]
Hence, the discriminant of f is 0
From the value of the discriminant, we can determine the number of x intercepts of the graph;
When D = 0, then; there exists only one x-intercept and it as calculated as thus
[tex]x = \frac{-b}{2a}[/tex]
Recall that
[tex]a = -4\\b=12\\c=-9[/tex]
So, [tex]x = \frac{-b}{2a}[/tex] becomes
[tex]x = \frac{-12}{2 * -4}[/tex]
[tex]x = \frac{-12}{-8}[/tex]
[tex]x = \frac{12}{8}[/tex]
[tex]x =1.5[/tex]

Jane works 3 times as fast as Eleanor. If they work together they can do a job in 21 minutes. How long does it take Eleanor to do the job by herself?
Answer:
1 hour and 24 min
Step-by-step explanation:
Jane does 3/4 job done in 21 min
Eleanor does 1/4 job done in 21 min
21*4=84
60+24
1 hour and 24 min
The work rate when they work together is much higher than when Eleanor
does the job herself.
It will take 84 minutesReasons:
Jane's work rate = 3 × Eleanor's work rate
The time it takes both Jane and Eleanor to do a job = 21 minutes
Required:
The time it would take Eleanor to do the job herself.
Solution:
Let x represent the portion of the job performed by Eleanor in the 21
minutes, we have;
The portion performed by Jane = 3 × x
Therefore;
The job done when they work together for 21 minutes = x + 3·x = 4·x
The time it takes Eleanor to do the job portion, x = 21 minutes
Therefore;
The time it will take Eleanor to do a job of 4·x = 4 × 21 minutes = 84 minutes
The time it would take Eleanor to do the job herself = 84 minutesLearn more about work word problems here:

A grocer wishes to blend two different coffee brands in order to make a blend of 400 pounds to sell at $3.00 a pound. If he uses a brand of coffee worth $2.70 a pound with another brand worth $3.20 a pound, how many pounds of each does he use?
Answer:
160 pounds at 2.70
240 pounds at 3.20
Step-by-step explanation:
Let x be the pounds and 2.70 per pound
400-x is the pounds and 3.20 per pound
there will be 400 pounds and 3.00 per pound
2.70 x + (400-x) *3.20 = 400 *3
Distribute
2.70x +1280-3.20x = 1200
Combine like terms
-.5x +1280 = 1200
Subtract 1280 from each side
-.5x = -80
Divide each side by -.5
x = -80/-/5
x =160
160 pounds at 2.70
400-160 = 240 pounds at 3.20
