Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

Step-by-step explanation:
M is the midpoint if AB . If coordinates of A are (-1,5) and the coordinates of M are (3,3) , what are the coordinates of B?
Answer:
The co-ordinates of B are ( 7,1)
Step-by-step explanation:
Step(i):-
Given that 'M' is the midpoint of AB
Given co-ordinate points are A(-1,5) and midpoint M(3,3)
we know that the midpoint formula
[tex]midpoint = (\frac{x_{1} +x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
[tex](3,3) = (\frac{-1+x_{2} }{2} ,\frac{5+y_{2} }{2} )[/tex]
Step(ii):-
Equating
[tex]3 = \frac{-1+x_{2} }{2}[/tex] and [tex]\frac{5+y_{2} }{2} = 3[/tex]
cross multiplication, we get
6 = -1 + x₂ and 6 = 5 +y₂
x₂ = 6+1 and y₂ = 6-5
x₂ = 7 and y₂ = 1
Final answer:-
The co-ordinates of B are ( 7,1)
what is the the constant of proportionality
X: 0 2 4 6
Y: 0 3 6 9

Answer:
8) Onaje is correct
9a) answers could be: 3(6y) or 4y + 6y + 8y or 2(2y + 3y + 4y)
b) all answers simplify to be 18y
Step-by-step explanation:
Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t
16t + 9t only equals 25t
Answer:
8. Onaje's expression is correct.
Step-by-step explanation:
The price, t, of the medium T-shirts can be represented as 16t, or 16 × t.
The price, t, of the large T-shirts can be represented as 9t, or 9 × t.
16t + 9t = (16 + 9) × t = 25t
Answer:
9. Part a: The expression could be 9y - 3y + 12y.
9. Part b: 9y - 3y = 6y
6y + 12y = 18y
Identify the slope and y-intercept. If the equation is in standard form, you may need to switch it to slope-intercept form. Sketch the graph of each line.
5x + 4y = 4
Answer:
Slope= -5/4
Y-intercept= 1
Step-by-step explanation:
First put into slope-intercept form, which would get y= -5/4x+1.
Then identify what's what, with the formula y=mx+b, where m is the slope and b is the y intercept. Using that you can see that -5/4 is the slope and 1 is the y.
Which letter is in the solution set for graph #2
Answer:
AStep-by-step explanation:
y > 0 - the region above the line together with that line
y ≥ 0 - the region above the line together with that line
y < 0 - the region below the line without that line
y ≤ 0 - the region below the line together with that line
We have:
y > 2 - the region above the line together with that line
y ≥ 2x - 3 - the region above the line together with that line

Answer:
x = 23
Step-by-step explanation:
the angles in a triangle add up to 180
the square means 90
90 + 67 + x = 180
157 + x = 180
157 - 157 + x = 180 - 157
x = 180 - 157
x = 23

Find the length and width of a rectangle.
Perimeter = 50
Side A = 3x + 2
Side B = x - 5
Step-by-step explanation:
Perimeter = 2 * (Side A + Side B)
= 2 * (3x + 2 + x - 5)
= 2 * (4x - 3)
= 8x - 6.
We have 8x - 6 = 50, so 8x = 56 and x = 7.
Length of rectangle = 3(7) + 2 = 23.
Width of rectangle = (7) - 5 = 2.
Answer:
Length of rectangle = 3(7) + 2 = 23.
Width of rectangle = (7) - 5 = 2.

The sum of the digits of a two-digit number is 11. When the digits are reversed, the new number is 27 more than the original number. Find the original number. Check your answer.
The original number is 38.
The original number is 47.
The original number is 74.
The original number is 83.
Answer:
-44+-11=11
Step-by-step explanation:
la respuesta es 54 y sí está bien gracias ahora adiós que tengas un buen día 33. Entonces -44 + -11 = 11 pero esa es la billetera que tengo.
Answer:
47
Step-by-step explanation
83 - 38 doesn't equal 27 and it said 27 more so it couldn't be 74 because if it was, it would be 27 less. So the only number left is 47!

Answer:
x = 7/12
Step-by-step explanation:
20 = 15(x + 3/4) (Given)
20 = 15x + 45/4 (Distribute)
35/4 = 15x (Subtract 45/4 on both sides)
7/12 = x (Divide 15 on both sides)
You can substitute the solution for x to check.
20 = 15(7/12 + 3/4)
20 = 15(4/3)
20 = 20
