Select the expression represented by the tiles. Remember, red tiles represent negative
quantities.
A. xsquared + 3x – 4
B. xsquared + 7x - 4
C. – xsquared-7x -4.
D. - xsquared + 3x -4
x^2 + 5x - 2x - 4
= x^2 + 3x - 4

Answer:
5
Step-by-step explanation:
4x-10=2x - Original equation
4x=2x+10 - Move constant to the right-hand side and change its sign
4x-2x=10 - Move variable to the left-hand side and change its sign
2x=10 - Combine like terms and divide both sides by 2
x=5 - Answer
Hope this helps!!!
Answer:
C. 16
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
If the coordinates of two points on the number line are a and b, then the distance between the two points is
d = |a - b|
The coordinates here are -9 and 7.
distance = |-9 - 7| = |-16| = 16
Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
