Do only equations with variables on both sides have no solution? Or can the variable be just on one side? Justify your answer.
Choose the correct answer below.
A.
Any equation can have one solution, infinitely many solutions, or no solutions. This does not depend on whether the variable appears on only one side or on both sides.
B.
Every equation with variables on both sides has no solution. However, it is also possible for an equation with the variable on only one side to also have no solution.
C.
If the variable only appears on one side of an equation, then the equation can always be solved for the variable. By contrast, an equation with variables on both sides always has no solution or infinitely many solutions.
D.
If the variable only appears on one side of an equation, then the equation can always be solved for the variable. This means that if an equation has no solution, then the variable must appear on both sides.
Answer:
A
Step-by-step explanation:
..................
The number of solutions, an equation can have is independent of the position of the variable.
An equation can have:
1 solutionInfinitely many solutionsNo solutionsIrrespective of where the variable appears
Take for instance:
[tex]x + 5 = 17 - x[/tex]
To solve this, we start by collecting like terms
[tex]x + x = 17- 5[/tex]
[tex]2x = 12[/tex]
Divide both sides by 2
[tex]x = 6[/tex]
In the above scenario, the variable (x) appears on both sides of the equation and the equation has 1 solution.
Another case scenario is as follows:
[tex]x + 5 = x[/tex]
Collect like term
[tex]x - x = -5[/tex]
[tex]0 = -5[/tex]
The above scenario shows that the equation has no solution and the variable (x) appears on both sides of the equation.
So, we can conclude that, an equation can have:
1 solutionInfinitely many solutionsNo solutionsIrrespective of where the variable appears
Hence, option (a) is correct.

8. Find y when x = 3, if y = -4 when x
= -9.
Answer:
x = 3, y = 8.
Step-by-step explanation:
So if x = 3, and y = ?,
Its the same as if y = -4 when x = -9.
Find the difference between 3 and -9.
3 - (-9) = 12 because when you subtract a negative number, the second negative sign flips the direction your going on the number line. We just found the absolute value. Now the oppisite of 12 is -12. Final answer is -12.
Let's do the same thing to the -4, but subtract -12.
-4 - (-12) = 8.
So if x = 3, y = 8
a school built a new gym the gym is rectangular and has an area of 6,000 square feet. if the gym is 100 feet long how wide is it
Using the formula of the area of the rectangle, the required width of the rectangular gym is 60 ft.
What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can also be defined as an equiangular quadrilateral since equiangular indicates that all of its angles are equal; or a parallelogram containing a right angle.
An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°).
A rectangle has equal and parallel opposite sides.
A rectangle has two dimensions—length and width—because it is a two-dimensional form.
So, we know that the area is:
6000 ft²
And the length is 100 ft.
Then the width will be:
Area = l * w
6000 = 100 * x
x = 6000/100
x = 60 ft
Therefore, using the formula of the area of the rectangle, the required width of the rectangular gym is 60 ft.

Find the 15th term of the arithmetic sequence whose common difference is d= 7 and whose first term is a1 = 5
Answer:
The 15th term is 103
Step-by-step explanation:
Arithmetic Sequence
An arithmetic sequence is a list of numbers with a definite pattern by which each term is found by adding or subtracting a fixed quantity to the previous term. If n is the number of the term, then:
[tex]a_n=a_{n-1}+d[/tex]
Where d is called the common difference. If we know the first term, the nth term is calculated by:
[tex]a_n=a_1+(n-1)*d[/tex]
The question asks us to find the term n=15 of an arithmetic sequence with a common difference d=7 and first term a1=5.
Applying the formula above:
[tex]a_{15}=5+(15-1)*7[/tex]
[tex]a_{15}=5+14*7[/tex]
[tex]a_{15}=5+98=103[/tex]
The 15th term is 103
