Answer:
Step-by-step explanation:
x -4 , 3x-11 , 5x - 18 ,.......
first term = a = x -4
Common difference (d) = second term - first term
= 3x -11 - [ x - 4]
= 3x - 11 - x + 4
= 3x - x - 11 + 4
= 2x - 7
nth term = a + (n-1)*d
12th term = x - 4 + 11*(2x - 7)
= x - 4 + 11*2x - 7 *11
= x - 4 + 22x - 77
=x + 22x - 4 - 77
= 23x - 81
What type of transformation is the image portraying?
options:
Dilation
Reflection
Rotation
Translation
Answer:
Reflection
Step-by-step explanation: A reflection is a transformation that acts like a mirror.
Answer:
Reflection
Step-by-step explanation:
Translations are a horizontal and/or vertical movement of a shape. In this case, the points wouldn't match up. A dilation is either growth or reduction, which this pretty obviously is not. A rotation also wouldn't properly match the points up. If we reflect this shape across a line directly in between the two, all the points will match up.

how to know if an angle is congruent?
Answer:
Two angles are congruent if they have the same measure. If you didn't already know, when two lines intersect the vertical angles formed are congruent. For example, all the angles in a square are congruent. All the angles in a regular pentagon are 108°, therefore all the angles are congruent because they are the same.
Step-by-step explanation: Hope this helps:).........if not sorry:(
Answer:
Well, AN angle (as you've stated in your question) can't, by definition, be congruent; you need at least two angles. Once that condition is met, then we can say that two angles are congruent if they have the same measure.

Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.

The limits are important in calculus and mathematical analysis and can be used to define integrals, derivatives and continuity. The limit of the given function is 4.
What is limit of a function?In mathematics, the limit is defined as the value that a function approaches the output for the given input values. It is used in the analysis process and it always concerns about the behaviour of the function at a particular point.
The upper and lower limits are used to define the definite integrals whereas the indefinite integrals are defined without using the limits and it have an arbitrary constant while integrating the function.
The limit of the given function is:
limₓ → -1 (2x² + 3x + 5)
(2 × (-1)² + 3 × (-1) + 5)
(2 × 1 + (-3) + 5) = ( 2 - 3 + 5)
= 4
So the limit of the given function is 4.

help please I need this by sunday!!!!!
Answer:
There are infinitely many solutions.
Step-by-step explanation:
So there are three possible scenarios. The is a finite set of solutions, there are infinitely many solutions, or there are no solutions.
We can determine which of these scenarios is possible by analyzing the pair of equations.
Y = (1/4)x - 1
Y = (1/4)(x - 4)
For clarity, I have put parentheses around the fractional component 1/4.
Note, the first equation can be rewritten as such:
Y = (1/4)x - 1
Y = (x/4) - 1
And the second equation can be simplified using the distributive property of multiplication
Y = (1/4)(x - 4)
Y = (1/4)x - (1/4)(4)
Y = (x/4) - (1)
Y = (x/4) - 1
Notice, both equation are actually the same. This means whatever values of x or Y you put in, the two equations will always be equal. This means there are infinitely many solutions because there are an infinite combination of x and Y that solve pair of equations given, which is actually the same equation. In the graph, this is represented as a line on top of the existing line.
Cheers.

The area of the poster is (x^2+2x-15) inches the width is (x-3) inches calculate the dimensions of the poster board when x=14
Answer:
The poster is 11 inches wide and 19 inches in height.
Step-by-step explanation:
We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:
((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.
Therefore:
Height= 19 Inches
Width= 11 Inches
Total Area= 209 Square Inches

Tri scored a total of 31 points in the basketball game, and he scored p points in the second half of the game. Write an expression to determine the number of points he scored in the first half of the game. Then, find the number of points he scored in the first half of the game if he scored 7 points in the second half of the game
Please No Fake Answers this QUESTION IS ALOT OF POINTS ON A TEST
Answer:
If he scored x points in the first half, then x + p = 31
Answer:
expression: y = 31 - pHe scored 24 points in the first half.expression:
first half points + second half points = total points obtained
Let first half points be y
y + p = 31
y = 31 - p ......this is the expression.
solve:
y = 31 - p
y = 31 - 7
y = 24 points
Giana, Kemi, and Matava each have $1.65 in their pockets. They decide to combine the money. How much money do they have altogether?
Answer:
$4.95
Step-by-step explanation:
If three people have $1.65 each, to find out how much money they have all together, you just multiply $1.65 by 3 (or add $1.65 3 times)
1.65 x 3 = 4.95
So all together, they have $4.95.
I hope this helps!
Answer:
Altogether they have 4.95$
Step-by-step explanation:
Giana, Kemi, and Matava are three people who each have 1.65$. So if they all combine it they will have 3×1.65$ which is =4.95$.

Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).
