For number 9 just take the two functions and multiply or add them I can’t tell what sign that is
In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.
Let's start with the first equation.

Cross multiply both sides of the equation.


Subtract 6x on both sides of the equation.


Divide both sides of the equation by -5.


Therefore, the slope of the first equation is 4/5.
Let's now simplify the second equation.

Add x on both sides of the equation.


Divide both sides of the equation by -4.


Therefore, the slope of the second equation is -5/4.
Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.

Answer:
The reasonable measurement in question 1 is D - the distance from New York to California is 2,250 miles. The best unit of measurement for the length of the distance of your textbook is A - inch.
Step-by-step explanation:
The United States uses the Imperial System of measurement which uses things such as inches, feet, yards and miles. In order to understand reasonable measurements, you need to first realize the order in which size would be determined. For instance, 12 inches is equal to one foot, which can be found on your typical ruler. Additionally, three feet is equal to one yard, which we can find on a yard stick. Lastly, there are 1,760 yards in one mile, which is typically measured with some time of pedometer/odometer. So, when you think about calculating measurement for common things such as a pencil or distance between cities, think about whether this distance could be measured using a ruler or perhaps the odometer on a car.
