Give two systems of equations that would be easier to solve by substitution than by elimination. Then give two systems that would be easier to solve with elimination. Finally, explain how you decide whether to use elimination or substitution to solve a system.​

Answers

Answer:

Answer: These techniques for elimination are preferred for 3rd order systems and higher.  They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b.  Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method.  As the system of equations increases, the "condition" of a matrix becomes extremely important.  Some of this may sound completely alien to you.  Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n')  become larger than 2.

Step-by-step explanation:

Example:

 

4X + 5Y = 9

5X -  4Y = 1

An isosceles triangle (2 sides are equal) has a base of 5 cm and legs "x" cm long. The perimeter is no more than 30 cm. Write an inequality to find the possible values of x.

Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon. How long is the BLUE ribbon if the length of the RED ribbon is 12 inches?

Answers

r = red, b=blue

r = b-7
12= b-7, add 7 to both sides
19= b

Checking answer, if blue is 19 inches, 7 inches less than that is 12, which is the length of the red.
The blue ribbon is 19 inches long

Write and solve an equation that can be used to find the value of x then find the perimeter of each shape

Answers

Answer:

Equation: (2x+5)4=(2x+8)3

X: 2

Perimeter: 36

Step-by-step explanation:

You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.

So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.

That leaves you with 2x=4. Dividing 2 by both sides means x=2

You can plug this in to prove if it is correct.

16+20=36

12+24=36

Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)

Four graphs are shown below:

Scatter plot A is shown with data points that move in an upward direction and are located at 1 and 0.3, 2 and 1, 3 and 2, 4.1 and 4, 5.2 and 6.1, 5.9 and 9.5. Additional points are located at 4.6 and 5, 5.8 and 7.4, 5.2 and 7.1. Scatter plot B shown with data points that move in an upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Scatter plot C shown with data points that move in a downward direction and are located at 0.1 and 8.7, 4 and 5.6, 5 and 4.3, and 6 and 0.5. Additional points are located at 5.9 and 1.5, 5.5 and 3.5. Scatter plot D is shown with points that move in a downward direction and are located at 0 and 7, 1 and 6, 2, and 5, 3 and 4, 4 and 3, 5 and 2, 6, and 1.

The required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.



Graphs have been shown below, the graph with the positive linear association between x and y to be determined.


What is a graph?

The graph is a demonstration of curves that gives the relationship between x and y-axis.

Options C and D can be omitted first because question asked for positive linear association between x and y, but in both graphs have negative associations so both options are incorrect.
While Option A and B have a positive association but graph A does not have a linear association so graph A will also be omitted. Graph B has a linear association because a straight curve represents linearity.

Thus, the required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.
