Answer:
B 126, 126+7 equals 18 so thats the answer
The first half is -0.012
The second half is 0.05
When add together you get an answer of 0.38
It is always an acute angle, even if the angle was the minimum 1 degree the complement is still 89 degrees which is still acute
Answer: x=6 and y = -4 and x= -1 and y=3
Step-by-step explanation:
Your two equations are y = -x + 2
and y=x^2 -6x + 8
Subsituting y=-x+2, we get
-x + 2 = x^2 -6x + 8
x^2 -5x +6 = 0
Solving by the quadratic formula gives,
(5+/- sqrt(25+24))/2
Thus, the two solutions are 6, and -1.
So x=6
y= -4 and
x=-1
y= 3
