Answer:
VW = √2
Step-by-step explanation:
y = x+1
x²+y²+2x+2y+1=0 (x²+2x+1) + (y²+2y+1) = 1
(x+1)² + (y+1)² = 1 : Circle: (x-h)² + (y-k)² = r² Center (O): (h , k) = (-1 , -1) r = 1
solve for roots: x²+(x+1)²+2x+2(x+1)+1=0
2x² + 6x + 4 = 0 x²+3x+2=0
(x+1)(x+2)=0
x = -1 or x = -2
y = 0 or y = -1
V and W: (-1 , 0) and (-2 , -1) forms a 90° center angle
√vw = √1²+1² = √2
<span>C = AB + D
AB = C - D
B = (C-D)/A
B = C/A - D/A</span>
Answer:
Step-by-step explanation:
g(x) = -4x + 5....find g(5)....sub in 5 for x
g(5) = -4(5) + 5
g(5) = -20 + 5
g(5) = -15 <===
477>80 is correct
-4.5<3 this one is also correct
Answer:
There was a %5 increase
Step-by-step explanation:
You just have to substract 65-60 and you get 5
