can anybody plzz helpme understand what domain ,funtions and range are?

Answers

Answer 1
The domain is all input values(otherwise known as all x-values on the x-axis) and the range is all possible output values( y-values, as shown on the y-axis). Functions are expressions involving 1 or more variables, in a function x-values are only allowed 1 y-value or else it isn’t considered a function.

Hope this helps!

Which expression is equivalent to 4/5x + 1 1/5?
A. 1/5 (4x + 1)
B. 2/5 (2x + 3)
C. 4/5 (x + 2)
D. 5/4 (x + 1)
I'd love it if you gave me an explanation for this.

Answers

Answer:

The answer would be B!

Step-by-step explanation:

To find which expression is equivalent, do the distributive property.

A. 1/5 * 4x = 4/5x

    1/5 * 1/1 = 1/5

4/5x + 1/5  <--- This is wrong!

B.  2/5 * 2x = 4/5x

    2/5 * 3/1 = 6/5 = 1 1/5

4/5x + 1 1/5 <--- This is correct!

C. 4/5 * x = 4/5x

    4/5 * 2/1 = 8/5

4/5x + 8/5 <--- This is wrong!

D. 5/4*x = 5/4x

    5/4 * 1/1 = 5/4

5/4x + 5/4 <--- This is wrong!

Therefore, the answer is B!  Hope this helps!

Find the equation of a line that is perpendicular to the line y=1/9x+4 and contains the point (-9,0).​

Answers

Answer:

When you are finding a line that is perpendicular, you need to look at the slope. In the format, y=mx+b, the m represents the slope. In this case, the slope (m) of the line is -1/9. A line with a perpendicular slope is the negative inverse. The negative inverse for -1/9 is 9/1. Once you know the slope, you can begin to plug in the new information in order to find the new b (y intercept).

New Line information:

m=9/1, (2,-5) --> this means that x = 2 and y = -5

y=mx+b

-5 = 9/1(2) + b

-5 = 18 + b

-23 = b

Once you find the b, you plug the b and m into the equation y = mx + b

y = 9/1x -23
