Answer:
140.74
Step-by-step explanation:
1.area of right triangle
1/2*b*h=1/2*20*18=180
2.area of semi circle
1/2*pi*r^2=1/2*pi*5^2=39.26
r= d/2
180-39.26=140.74
Answer:
(5,0)
Step-by-step explanation:
x = 5
y = 0
(I love these kind of q's, if anyone needs help!)
:D
Since we know the slope intercept form is y=mx+b and that parallel lines have the same slope we know that the slope in our equation is going to be -4
we can plug in the point (-8,5) into y= -4x+b
in doing that we get 5= -4(-8)+b.
5=-4(-8)+b
5=32+b
subtract 32 from both sides to find b the (y-intercept)
5-32=-27
b=-27
bc the slope is -4 and the y-intercept is -27 the equation of the line that's parallel to y=-4x+5 and passes through the given point (-8,5) is y=-4x-27
Answer:
The answer is x=-3.
Step-by-step explanation:
10x+9=4x-9
10x-4x+9=4x-4x-9
6x+9=-9
6x-9+9=-9-9
6x=-18
x=-3
