Answer:
Step-by-step explanation:
An equation contains a sign equality (=) between two expressions.
And an expression is a simple algebraic statement.
By these definitions,
Equations Expressions
x = 2x + 5 21x - 13 + 11x
-3.7x - 13
3x + 1 = -2.1 
Answer: OPTION C.
Step-by-step explanation:
The systems of linear equations can have:
1. <u>No solution:</u> When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. <u>One solution</u>: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. I<u>nfinitely many solutions</u>: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts <em><u>never</u></em> have more than one solution.
Answer:
11 cm
Step-by-step explanation:
As Y is midpoint if XZ
XY=YZ=2a+1
WZ=WX+XY+YZ=28
a+1+2a+1+2a+1=28
5a+3= 28
5a=25
a=5
XY=2a+1
=2(5)+1
=10+1
=11 cm
Answer:
2x squared + 2x + 3
Step-by-step explanation:
you can either use synthetic division or use long division. either way will work. search up synthetic and long division on y___ube and you should get it
