1 gallon is $4.20
16.80/5=4.20

- Evaluate the expression ⇨ (-6) squared.


This will be equal to..

Multiply -6 by itself (squaring a number means to multiply the number by itself twice)

-6 multiplied by-6 will get you 36 as the answer.

Answer:
your answer is y = 8/3
Step-by-step explanation:
If the line that goes through (9, 6) is perpendicular to y = -1/3x + 7, then their slopes will be opposite reciprocals. The slope of the line given is -1/3. The opposite reciprocal of -1/3 is +3. If we have our new line passing through point with x coordinate 9 and y coordinate 6, we will use that x and y and the slope of 3 to solve the slope-intercept equation for b. Like this: 9 = 3(6) + b. 9 = 18 + b and b = -9. That means that the new equation, the one that is perpendicular to the given line, is y = 3x - 9.
