Answer:
y = -2.25
Step-by-step explanation:
-8(3y+5) = 14
-8(3y+5)/-8 = 14/-8
3y+5 = -1.75
3y+5-5 = -1.75-5
3y = -6.75
3y/3 = -6.75/3
y = -2.25
The area of the square is 9, the area of all the semi circles added together is 15.7, when you add them together you get 24.7
Answer:
(x=0, y=11)
(x=2, y=9)
Step-by-step explanation:
first equation substitution for x first.
y=11-x
plug into 2nd equation
(x+2)^2+(11-x-7)^2=20
this should lead you into a quadratics equation.
you get x=0, x=2.
do the same for y value this time, subbing in the x value
(11-y+2)^2+(y-7)^2=20
this also leads into a quad equation
solve and you get y=11, and y=9
A. 12.2%
Steps:
1) 1380-1571= -191
2) -191/1571= -0.12
3) -0.12(100) = 12.15 = 12.2%
Answer:
-3
Step-by-step explanation:
f(-2) = (-2)^2 + 10 = 14 -> (-2, 14)
f(-1) = (-1)^2 + 10 = 11 -> (-1, 11)
(11-14)/(-1-(-2)) = -3/1 = -3
