Answer:
20
Step-by-step explanation:
Replace the variables with their corresponding numbers.
y-x/z 64-4/3 60/3 20
Slope intercept form is y = mx + b
So if you start with 9x - 7y = -7, the first thing you need to do is move the 9x to the other side of the equation by subtracting it from both sides.
9x - 7y = -7
-9x -9x
Now you have -7y = -9x -7
For the equation to be in slope intercept form now you should divide every term by the number in front of your y. In this case divide every term by -7
-<u>7y</u> = <u>-9x</u> <u>-7</u>
-7 -7 -7
That leaves you with: y = 9x/7 + 1
Answer:27^n+3–6*3^3n+3–n*9^n+2
Step-by-step explanation:
This will be a little complex number...
assume 35 years ago, it cost x dollars
for now: x×
=25.25
solve it! :) maybe too difficult without a calculator
