Answer:
.4 repeating
Step-by-step explanation: divide the top number by the bottom number so 4 divided by 9
Answer:
y = 3x - 6
Step-by-step explanation:
slope intercept form is: y = mx + b
m is your slope, so figure it out by doing rise/run
you rise 3, over one which is 3/1, but simplifies to 3
b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6
therefore, your answer is: y = 3x - 6
As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10
<h3>
Evaluating expressions:</h3>
Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:

And we want to evaluate it in:

So we just need to replace k by that value in the above expression, we will get:

Now we can just solve this:
