Drag the answers into the boxes to match each system.
{4x−2y=102x−y=5
{y=2x−3−2x+y=−5
{2x−5y=143x+4y=10
Answers:
Consistent Indpendent
Consistent Dependent
Inconsistent
Answer:
(dependent)
(Incosistent)
(Independentt)
Step-by-step explanation:
{4x−2y=102x−y=5
{y=2x−3−2x+y=−5
{2x−5y=143x+4y=10
The system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
A) The given system of equations are 4x−2y=10 and 2x−y=5
4/2 = (-2)/(-1)=10/5
2=2=2
Since, a₁/a₂ =b₁/b₂=c₁/c₂
The system of equations have infinitely many solution, so they are consistent dependent.
B) y=2x-3 and -2x+y=-5
Here, 2x-y-3=0 and -2x+y+5=0
2/(-2)=(-1)/1≠(-3)/5
-1=-1≠(-3)/5
Since, a₁/a₂ =b₁/b₂≠c₁/c₂
The system of equations are parallel, so they are inconsistent equations.
C) 2x−5y=14 and 3x+4y=10
Here, 2x-5y-14=0 and 3x+4y-10=0
2/3≠(-5)/4≠(-14)/(-10)
Since, a₁/a₂ ≠b₁/b₂
The system of equations have unique solution, so they are consistent independent.
Therefore, the system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

1. Rachel used the white basket.
2. Rachel carried 4 more apples than the Girl with the red basket.
3. The girl that carried 20 apples is either the girl that used the red basket or Rachel.
The solution is, It is not reasonable to say they can carry 15 feet with each person taking only one turn.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
given that,
Kevin=5 feet
Rachel=3 feet further than Kevin=(3+5)=8 feet
Daniel=half as far as Rachel=(1/2)×8=4 feet
If each person takes one turn;
Total distance covered=(Kevin's distance+Rachel's distance+Daniel's distance)
Replacing;
Total distance covered=(5+8+4)=17 feet
17 feet≠15 feet
It is not reasonable to say they can carry 15 feet with each person taking only one turn.

What do squares and rhombuses have in common?
Check all that are true.
Both shapes are quadrilaterals.
Both shapes have all sides of equal lengths.
Both shapes have equal opposite angles.
Both shapes have four right angles.
Both shapes have parallel opposite sides. plz help me i give you branlyest
Answer:
Everything except the third one.
Step-by-step explanation:
A quadrilateral has 4 sides and 4 angles which both shapes do. The next 2 and the last one are correct because squares are classified with the rules. All sides are equal, all angles are the same size and have all parallel sides. Rhombuses are called rhombuses because they have all sides measuring same length, opposite angles are equal, have 4 angles, and opposite sides are parallel.
The correct statements are :
1) Both shapes are quadrilaterals.
2) Both shapes have all sides of equal lengths.
3) Both shapes have four right angles.
4) Both shapes have parallel opposite sides
Given,
Square and rhombus.

What is the distance between point A and point B?
Enter your answer in the box.
The distance between points A and B on the number line is
units.
Answer:
The distance is 11 units
Step-by-step explanation:
Given
See attachment
Required
Determine the distance between A and B
From the attachment:
[tex]A = -1[/tex]
[tex]B = 10[/tex]
This distance (D) is calculated using the following expressions:
[tex]D = B - A[/tex]
Substitute values for B and A
[tex]D = 10 - (-1)[/tex]
[tex]D = 10 +1[/tex]
[tex]D = 11[/tex]
The distance is 11 units
