Step-by-step explanation:
y=|4-3x| y: positive number
Let acute angle be x.So x+5x+90=180 so x=30
First we need to find the slope of the given line. And for that we need to bring the equation in y=mx +b form where m is the slope. And for that, we need to solve the given equation for y.
0.5x-5y=9
Moving 9 to the left side
0.5x-5y-9=0
Moving 5y to the right side
0.5x -9 = 5y
Getting rid of 5 by dividing both sides by 5, that is
0.1x -(9/5)=y
or y=0.1x -(9/5)
Therefore slope of the given line is 0.1 and parallel lines have same slopes. Therefore slope of the parallel line is 0.1 too .
B)257.1
Explanation: Area of a square : length x width
Area of square = 12x12= 144
Area of a circle: pie(radius)^2
diameter:12
radius:12/2=6
Area of a circle: pie(6)^2=113.1
ADD BOTH AREAS
Area of the figure =144+113.1
=257.1
