x +3=0
Determine which of the following equations define a function. For - 1

Answers

Answer 1
Answer: x + 3 = 0 is not a function because it is a vertical line.

A vertical line has undefined slope because all points the line have the same x-coordinate.

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

Remember that a function can only take on one output for each input. Since a vertical line has the same x-coordinates for all values of y-coordinates, then it means that it is not a function.

Factor the following expression...
x^2 - 2x - 3

Answers

Trying to factor by splitting the middle term

 1.1     Factoring  x2-2x-3 

The first term is,  x2  its coefficient is  1 .
The middle term is,  -2x  its coefficient is  -2 .
The last term, "the constant", is  -3 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3 

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   -2 .

     -3   +   1   =   -2   That's it


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  1 
                     x2 - 3x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (x-3)
              Add up the last 2 terms, pulling out common factors :
                     1 • (x-3)
Step-5 : Add up the four terms of step 4 :
                    (x+1)  •  (x-3)
             Which is the desired factorization

Final result : (x + 1) • (x - 3)

Mr Morris earns $3500 per month. He deposits 2/7 of his salary every month. How much money will he deposit in 5 month.

Answers

5000, take 3500 multiplied by 2/7 to find the amount of money deposited per month which is 1000 then multiply it by 5 to find the deposit over 5 months
3500 x 2/7= 1000
1000 x 5 = 5000

He will deposit $5000 in 5 months

Solve the inequality 4x-7<5

Answers

4x - 7 < 5

Add 7 to the both sides,
4x - 7 + 7 < 5 + 7
4x < 12

Divide 4 from the both sides,
4x/4 < 12/4
x < 3

So, your final answer is x < 3

Hope this helps!
