Answer:
x = 30
Step-by-step explanation:
We know that the angle is a right angle, which is equal to 90. So in order to see what the equation is equal to, we have to subtract 81 from 90.
90 - 81 = 9
With the answer we get, we can now begin to solve for x.
2x - 51 = 9, add 51 to both sides
2x = 60, divide 60 by 2 to get x
x = 30
Now, to check your work, plug 30 into the equation.
2(30) - 51
60 - 51 = 9
hope this helps!! :]
Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.
Answer: The $75 rebate.
Step-by-step explanation: When you have a question that deals in percentages, you would place a decimal point in the second point back--- Or rather, it would be 1.00 at 100% and above, and .05 for 5%. You would be getting $71.25 discount with the 15%, while you would be getting $3.75 more with the $75 rebate.
