Answer:
#1 is 2x-12°=-12
#2 is x+34°=34
Step-by-step explanation:
when it tells you to add the second number will always be that number but a positive.
when it tells you to subtract the second number will always be that number but a negative.
plus=positive
minus=negative
remember that.
hope that helped you out!
Answer: y=-7x-45
Explanation: Two parallel lines have the same slope, so that means the slope of the line would be -7. When you add that value to your equation, that would give you: y=-7x+b. Now that you have the slope, the only other value you’re missing is b. To find the value of b, you can substitute any point into the equation that’s on the line and solve for b:
-3=-7(-6)+b
-3=42+b
b=-45
Now that you have the value of b, substitute it into the final equation:
y=-7x-45

Given:
The length of the rectangle = 16 ft
The width of the rectangle = 12 ft
The diameter of the semicircle = 12 ft
To find the area of the given figure.
Formula
where,
be the area of the given figure
be the area of the rectangle
be the area of the semicircle.
- The area of the rectangle =
where, l be the length and b be the width - Area of the semicircle =
, r be the radius of the semicircle.
Now,
The radius of the semicircle r = 6 ft
Putting, r=6, l=16 and b= 12 we get,
sq ft
or, 
sq ft
sq ft
or, 
sq ft
So,
sq ft
= 248.52 sq ft
Rounding off to the nearest tenth, we get;
A=248.5 sq ft.
Hence,
The area of the composite figure is 248.5 sq ft.
