This isn't an answer, rather a suggestion. I would use the website desmos to help me. But for future reference I can help you.
f(x) = - x+6 is similar to y=-x+6.
Simply plug in random numbers into the variable x (preferably ones that could fit on your paper like 0,1,2,3...)
Answer:
$57
Step-by-step explanation:
When you are asked to solve an equation, you need to isolate the variable which is t in this case. To isolate t, you would divide both sides by -5 and be left with t=-6 which is the final answer.
I hope this helps.
Answer:
the square root of 75 is either 
or 8.66
Step-by-step explanation:
In order to find which is the answer, we will go step-by-step. Numbers that are not followed by I are drawn on the Real Axis and the other ones are drawn on the Imaginary Axis. You go first on the Real Axis and then on the Imaginary Axis and intersect those 2 points. If a number does not have an imaginary or real part you can assume that is equal to 0. As you can notice the number that is not in the shaded area is <span>2 − I</span>
