So when we triple the value of "x" in that expression we also triple the value of "y". The corrrect answer is "x 3".

Step-by-step explanation:

For a given "x", y follows the expression: . We have a new input to the function, which we will call "a", we know that this value is 3 times the value of the prior "x", so we can calculate what will happen to "y" as shown below:

For when the input is "a":

We know that "a" is 3 times x, therefore:

Due to the associative property of the product we can rewrite the above expression as:

Since "8*x" is the same as the prior "y", then we have:

So when we triple the value of "x" in that expression we also triple the value of "y". The corrrect answer is "x 3".

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
