i dont understand the question
Answer:
Insert the numbers into the equation y=3x-5.
the rule states that in every equation the first number is x.so it will be -6=3(4)-5
-6=12-5
-6=7.
If u want, you can leave your answer like that
Answer:
10x+3y+2
Step-by-step explanation:
no it isn't. 2cos(x) is 2 multiplied by cos(x), cos (2x) is cos(2 multiplied by x) meaning 2x is the angle you're taking the cosine of. if you want to know what cos(2x) look up the double angle rule.
Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm
