Answer:the y=x graph will have a slope of positive one and the y intercept would be 0. The y=-x+4 graph will have a slope of negative one ( line going down) and have a y intercept of 4
Step-by-step explanation:
So, Cot is negative in second and fourth quadrant.
So, tan(x+
)=-cot(x)
Option B
Answer:
>
Step-by-step explanation:
4 is greater than 3
sqrt15 is greater than sqrt6
So 4+sqrt15 must be greater than 3+sqrt6
X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
