On January 1st you bought 100 shares of Ford Motor Company (F) for $8 per share . On October 2nd the stock price is $10 per share. You sell the 100 shares at $10 per share. How much did you make or lose (\$) ? What was your return on investment (ROl) ?
Answer:
$200; $800
Step-by-step explanation:
100 x8 =800
100 x10=1000
1000-800= $200 (what you earn)
the money that you pay back is the return on investment so $800
The amount of profit made by the shares is given by A = $ 200
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The cost of 1 share on January 1st = $ 8
The number of shares = 100
So , the total cost of 100 shares = $ 800
And , the cost of 1 share on October 2nd = $ 10
The number of shares = 100
So , the total selling price of 100 shares = $ 1,000
And , the profit A = total selling price of 100 shares - cost of 100 shares
On simplifying the equation , we get
The profit made A = $ 1,000 - $ 800
The profit made A = $ 200
Hence , the equation is A = $ 200

：Find x+y, if: 2x+3y=8 and 3x+5y=13
Answer:
x=1
y=3
Step-by-step explanation:
Heres a photo with explanation
The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
2x + 3y = 8 ...1
3x + 5y = 13 ...2
Multiply equation 1 by 3 and equation 2 by -2, then we have
6x + 9y = 24
-6x - 10y = - 26
Add the above equations, then we have
- 26 + 24 = 9y - 10y
y = 2
Then the value of the variable 'x' is calculated as,
3x + 5(2) = 13
3x + 10 = 13
3x = 3
x = 1
Then the value of the expression x + y is calculated as,
⇒ x + y
⇒ 1 + 2
⇒ 3
The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

How to write algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.a. Give 2 input-output pairs that represent this function.
There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.
Hence, the two pairs should be as,
(2, 50), (4, 100)
b. Write an equation that represents this function.As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,
[tex]v(n)=25\times n\rm \;\;cents[/tex]
c. Find the output when the input is 10.Put the value 10 on the place of n in the above equation as,
[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]
The output when the input is 10 is 250 cents.
d. Identify the independent and dependent variables.The independent value is the number of quarters and the dependent variable is the value of cents.
Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the equation that represents this function is,

How many solutions does this problem have
Y=-2x -4
Y= 3x plus 3
Answer:
There is one possible solution
Step-by-step explanation:
Here, we want to get the number of solutions
We can proceed to solve the equation
we have two y values so we can directly equate the x parts
-2x - 4 = 3x + 3
3x + 2x = -3-4
5x = -7
x = -7/5
To get y, we substitute
We can only get one value of y too
So we have a point (x,y) as the solution to the system of equations
Joe measures side lengths of triangular canvas to be 22 inches, 10 inches and 11 inches. Could those be correct measurements?
Answer:
Incorrect measurement
Step-by-step explanation:
Given
Shape: Triangle
Length: 22in, 10in and 11in
Required: Determine if the measurements are correct
For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.
i.e.
[tex]22 + 10 > 11[/tex] --- True
[tex]22 + 11 > 10[/tex] --- True
[tex]11 + 10 > 22[/tex] --- False
Since all three conditions are not true, then the measurements are incorrect
Find an equation for the perpendicular bisector of the line segment who’s endpoints points are (-9,3) and (1,7).
Answer:
y = 2/5x + 33/5
Step-by-step explanation:
(-9,3) and (1,7)
m=(y2-y1)/(x2-x1)
m=(7-3)/(1+9)
m=4/10
m = 2/5
y - y1 = m(x - x1)
y - 3 = 2/5(x + 9)
y - 3 = 2/5x + 18/5
y = 2/5x + 33/5

“The difference of –4 and the quotient of a number and –2” should be written as StartFraction negative 4 minus n over negative 2 EndFraction.
“The product of 3 and the difference of –4 and the quotient of a number and –2” should be written as 3 (negative 4) minus (StartFraction n over negative 2 EndFraction).
