Solve each system of equations by using elimination. a store placed two orders with a supplier. the first order was for 12 digital cameras and 8 camcorders for a total of $7640. the second order was for 9 digital cameras and 11 camcorders for a total of $8330. find a price of a digital camera and a camcorder.

camcorders= 290

digital cameras=520

Step-by-step explanation:

so firstly you will need to make two equations

12x+8y=7640

9x+11y=8330

Then eliminate the one you choose,

(11) 12x+8y=7640

(-8) 9x+11y=8330

132x+ 88y=84040

-72x-88y=-66640

now eliminate your Ys and add your Xs

60x=17400

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
