The graph of 4|x| is shaped like a V where the vertex is at the origin ( because when x = 0 y=0) All y values are positive ( because of the absolute value |x| )
Refection in the x-axis will make all the y values change from positive to negative so the answer is y = -4|x|
g(x) = -4|x|
1 and 3/4
takes out 1/4
so 1 and 3/4-1/4
remember that 1 and 3/4=1+3/4
remember that 3/4=1/4+1/4+1/4 so
1 and 3/4-1/4=1+1/4+1/4+1/4-1/4=1+1/4+1/4+(1/4-1/4)=1+1/4+1/4+(0)=1+1/4 +1/4=1+2/4=1+1/2=1 and 1/2
it called for 1 ad 1/2 cup
10. from the question; the circle theorem obeyed is "angled formed by semi-circle"
The angle formed in a semicircle is 90 degrees, hence
This gives
But
Substituting values we get
hence, x =12
