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.
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.

Example:
4X + 5Y = 9
5X - 4Y = 1

Write and solve an equation that can be used to find the value of x then find the perimeter of each shape
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:
A
Step-by-step explanation:
The line plot is obviously symmetric because if you fold it, you would get a perfect fold. It is not bell shaped because, well, it's not in the shape of a bell. It just creates a straight line of points. This just makes option A the only logical answer.

The distance from the car to the cabana is 3 units, and the distance from the cabana to the beach is 6 units. When measuring distance on a graph make sure to use absolute value, because distance can't be a negative number.
Answer:
It would be 9
Step-by-step explanation:
Just count how much units it took to get the cabana and that is 3 units then you count how much it takes to get to the beach from the cabana which is 6 then you add those and what do u get 9.

Which side lengths could create a triangle?
A. 5 cm, 5 cm, 15 cm
B. 5 cm, 10 cm, 20 cm
C. 10 cm, 10 cm, 15 cm
D. 10 cm, 10 cm, 20 cm
Answer:
b
Step-by-step explanation:
Answer:
C. 10 cm, 10 cm , 15 cm
Step-by-step explanation:
In order to form a triangle the sum of two sides of a triangle should exceed the third side so
if we use option B then
10 + 10 > 15
20> 15 (True) ✔
10 + 15 > 10
25 > 10 (True) ✔
Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x
