Line Q is represented by the following equation: 2x + y = 11
Which equation completes the system that is satisfied by the solution (3, 5)? (4 points)
a
x + 2y = 15
b
x + y = 15
c
x + y = 8
d
x − y = 2
Answer:
C) x+y=8
Step-by-step explanation:
I enter (3,5) into 2x+y=11
2*(3) + 5 = 11
11=11 correct
You now you need to enter the (3,5) into all the equations and see if they are correct
A: x + 2y = 15
3+ 2*5=15
13 = 15 is not correct
B. X+ y = 15
3+5= 15
8=15 not correct
C.x + y=8
3+5=8
8=8 correct
D. X-y = 2
3-5=2
-2= 2 not correct
Answer:
The answer is C

What is the LCD of 1/2 and 2/17
Answer:
34
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/2, 2/17
For the denominators (2, 17) the least common multiple (LCM) is 34.
LCM(2, 17)
Therefore, the least common denominator (LCD) is 34.

1. Here are the first 5 terms of a quadratic sequence.
1
3
7
13
21
Find an expression, in terms of n for the nth term of this quadratic sequence.
9514 1404 393
Answer:
n² -n +1
Step-by-step explanation:
First differences of the terms of the sequence are ...
3-1 = 2
7-3 = 4
13-7 = 6
21-13 = 8
Second differences are ...
4-2 = 2
6-4 = 2
8-6 = 2
In a quadratic sequence the coefficient of the squared term is half of the second difference value. Here, that means the squared term will be (2/2)n² = n².
__
We can find the other terms of the quadratic expression by considering the differences between n² and the actual sequence.
The sequence of n² terms is ...
1, 4, 9, 16, 25
When we subtract these from the actual sequence, we get ...
1-1 = 0
3-4 = -1
7-9 = -2
13-16 = -3
21-25 = -4
That is, the amount subtracted from n² is one less than the term number.
The expression for the n-th term is ...
an = n² -n +1

Which pair of triangles can be proven similar by the AA ~ Postulate?
Answer: c
Step-by-step explanation:
The pair of triangles that can be proven similar by the AA ~ Postulate is triangle AXB and QXR.
The correct option is (C).
What is Similarity of Triangles?When the ratio between two triangles' sides is the same and both triangles' angles are equal, a triangle is said to have two equal sides.
Given:
In figure C,
In triangle AXB and QXR
<BAX = <QRX (given)
<AXB = QXR (Vertical opposite angle)
So, AA similarity Criteria triangle AXB and QXR is similar.
Hence, Figure C is following AA similarity.

Jeremy listed five rational numbers. Then he drew a number line to display and compare them.
Plot the numbers on the number line by dragging each one to the correct location.
6/3, -3/4, 1.5, 0.25, -5/4
Answer:
Step-by-step explanation:
A rational number is a number that can be written in the form [tex]\frac{a}{b}[/tex] where b ≠ 0.
In order to properly arrange the numbers on the number line, we need to arrange it in an ascending order.
6/3 = 2
-3/4 = -0.75
1.5 = 1.5
0.25 = 0.25
-5.4 = -1.25
The numbers written in an ascending order will be,
-1.25 = -5/4
-0.75 = -3/4
0.25
1.5
2 = 6/3
Therefore writing this on the number line, we will have it in this order:
-1.25, -0.75, 0.25, 1.5, 2
