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

Your answer is
X=8
The equation can be made by:
Letting x be the price of each tshirt sold
Y be the cost of washing cars
So the equation 1:
292.50 = 15x + 12y
Then the equation 2 is for this week:
<span>747.50 = 45x + 10y</span>
Use the compound amount formula: A = P(1+r)^t
Here, A = $2700(1+0.07)^3 = $3307.62
Luis will have accumulated $3307.62 to spend on his trib to Belize.
