ANSWER
Katnis is right
EXPLANATION
We use the Remainder Theorem to check if she is right.
According to the Remainder Theorem, if the polynomial function,
is divided by x+1, then the remainder is given by
We substitute x=-1 into the function to obtain,
We simplify to get:
Katnis is right because the remainder is zero
6x + ( 3x - 9) = 90°( being complementary angles )
6x+3x -9 = 90°
9x = 90° + 9
x = 99 / 9
x = 11
Step-by-step explanation:
(y+7)/(-9+7) = (x+10)/(-5+10)
(y+7)/(-2) = (x+10)/5
5(y+7)=-2(x+10)
5y+35= -2x-20
the equation :
5y=-2x-20-35
devided by 5
=> y = -2/5 x - 11
or y = -0.4x - 11
