Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
6x + 8y = 0
-7x + y = 31
Step 2: Rewrite Systems
-7x + y = 31
Add 7x to both sides: y = 7x + 31Step 3: Redefine Systems
6x + 8y = 0
y = 7x + 31
Step 4: Solve for x
Substitution
Substitute in y: 6x + 8(7x + 31) = 0Distribute 8: 6x + 56x + 248 = 0Combine like terms: 62x + 248 = 0Isolate x term: 62x = -248Isolate x: x = -4Step 4: Solve for y
Define equation: -7x + y = 31Substitute in x: -7(-4) + y = 31Multiply: 28 + y = 31Isolate y: y = 32y+ 3 = 15

What is the solution of the equation 70 = 1.4y ?
The solution of the equation 70 = 1.4y is 50.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 70 = 1.4y.
Seventy equal to one point four y.
In the given equation the variable is y.
We need to solve for the y.
70 = 1.4y.
Divide both sides by 1.4
70/1.4=y
Seventy divided by one point four equal to y
50=y
The value of y is fifty.
Hence, the solution of the equation 70 = 1.4y is 50.

O yes, because all the elements of set A are in set R
O yes, because all the elements of set R are in setA
O no, because each element in set A is not represented in set R
O no, because each element in set R is not represented in set A
Answer: BBBBBB
Step-by-step explanation:
The correct option is,
"Yes because all the elements of set R are in set A"
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given the following sets;
U = {x | x is a real number}
A = {x | x is an odd integer}
R = {x | x = 3, 7, 11, 27}
Hence, The elements of the set A are,
⇒ A = {1, 3, 5, 7, 9, 11...}
R ⊂ A can be interpreted as R is a subset of A
i.e all the elements of R can be found in A.
Since, all the elements of R are all odd integers and can be fi=ound in A, hence R ⊂ A is TRUE.
The correct option is "Yes because all the elements of set R are in set A"

Write the equation of the line that is parallel to y = -6x + 10 and crosses the y-axis at -4.
Answer:
y= -6x-4
Step-by-step explanation:
As two lines are parallel, their slope is same which is -6
Now, use:y-y1=m(x-x1)
y-(-4)= -6(x-0) (y1=-4,x1=0, cause the equation of y axis is x=0)
So,y= -6x-4

II. Mr. Roy sold a cupboard to Mohan for RO 60 and earned a profit of RO 10. Mohan spent RO 27 to polish and repair the cupboard. He then sold it to Gopi at a profit of RO 8. After using the cupboard for a year , Gopi sold it to a furniture dealer for RO 90. Did Gopi make a profit or a loss in the deal? *
Answer:
Gopi made a loss in the deal
Step-by-step explanation:
To solve this question, we'll analyse each statement in the question one after the other.
From Roy to Mohan,
[tex]Selling\ Price = Ro.\ 60[/tex]
The profit of [tex]Ro.\ 10[/tex] goes to Roy
Mohan spent [tex]Ro. 27[/tex] on polish and repairs.
So, the cost price of the cupboard becomes
[tex]Cost\ Price = Ro.60 + Ro.27[/tex]
[tex]Cost\ Price = Ro.87[/tex]
He sells at a profit of [tex]Ro.8[/tex]. to Gopi
So, the selling price is:
[tex]Selling\ Price = Ro.8 + Ro.87[/tex]
[tex]Selling\ Price = Ro.95[/tex]
At this stage, the cost price of the cupboard to Gopi is:
[tex]Cost\ Price = Ro.95[/tex]
and
[tex]Selling\ Price = Ro.90[/tex]
Profit is calculated as:
[tex]Profit = Selling\ Price - Cost\ Price[/tex]
[tex]Profit = Ro.90 - Ro.95[/tex]
[tex]Profit =- Ro.5[/tex]
Because; the profit is negative, then it is a loss.
[tex]Loss = Ro.5[/tex]
Gopi made a loss in the deal
