For the first florist you would do $12.50 divided by 4 as there are 2 flower bouquets and 2 vases = $3.125, which represents both b and v
As for the second florist you would do $29.00 divided by 10 as there are 8 flower bouquets and 2 vases. This results to $2.6, this represents the cost of one b and one v.
Answer:
7,7
Step-by-step explanation:
A vertex should be connected, so 7 as the x makes the most sense
![\bf f(x)=|x+2|\implies f(x)=\pm\sqrt{(x+2)^2}\implies f(x)=\left[ (x+2)^2 \right]^{\frac{1}{2}} \\\\\\ \cfrac{dy}{dx}=\stackrel{chain~rule}{\cfrac{1}{2}[(x+2)^2]^{-\frac{1}{2}}\cdot 2(x+2)^1\cdot 1}\implies \cfrac{dy}{dx}=[(x+2)^2]^{-\frac{1}{2}}(x+2) \\\\\\ \cfrac{dy}{dx}=\cfrac{x+2}{[(x+2)^2]^{\frac{1}{2}}}\implies \left. \cfrac{dy}{dx}=\cfrac{x+2}{\pm \sqrt{(x+2)^2}} \right|_{x=1}\implies \cfrac{3}{\pm 3}](https://tex.z-dn.net/?f=%5Cbf%20f%28x%29%3D%7Cx%2B2%7C%5Cimplies%20f%28x%29%3D%5Cpm%5Csqrt%7B%28x%2B2%29%5E2%7D%5Cimplies%20f%28x%29%3D%5Cleft%5B%20%28x%2B2%29%5E2%20%5Cright%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7Bdy%7D%7Bdx%7D%3D%5Cstackrel%7Bchain~rule%7D%7B%5Ccfrac%7B1%7D%7B2%7D%5B%28x%2B2%29%5E2%5D%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%5Ccdot%202%28x%2B2%29%5E1%5Ccdot%201%7D%5Cimplies%20%5Ccfrac%7Bdy%7D%7Bdx%7D%3D%5B%28x%2B2%29%5E2%5D%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%28x%2B2%29%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7Bdy%7D%7Bdx%7D%3D%5Ccfrac%7Bx%2B2%7D%7B%5B%28x%2B2%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%5Cimplies%20%5Cleft.%20%5Ccfrac%7Bdy%7D%7Bdx%7D%3D%5Ccfrac%7Bx%2B2%7D%7B%5Cpm%20%5Csqrt%7B%28x%2B2%29%5E2%7D%7D%20%5Cright%7C_%7Bx%3D1%7D%5Cimplies%20%5Ccfrac%7B3%7D%7B%5Cpm%203%7D)
check the picture below. the point 1,3 is on the increasing slope side, so will be 3/3 or 1.
Answer:
not enough information, I'd be able to help if there was sorry
