Your answer is 3
Answer:
x = 30
Step-by-step explanation:
Vertical angles have equal measures, so ...
2x +10 = 70
2x = 60 . . . . . . subtract 10
x = 30 . . . . . . . divide by 2
Descending order for a polynomial means from highest value of exponent to the lowest value of exponent.
If you observe the options you can see that polynomial shown in option A is only listed in descending order i.e. starting from a maximum exponent of x and then moving towards lower exponents of x.
So answer to this question is option A
P is (18, -16)
to find the answer, u would solve it in reverse order of the midpoint formula by first doing the x-values:
5(2)= 10-(-8) = 18
and then the same to y-values:
-10(2)= (-20)-(-4) = -16
to get:
(18, -16)
