The difference has 4 terms and a degree of 7. Profit is the difference between revenue and cost.
S= soft taco
d= double deckers
$11.25= 3s+3d
$10.00= 4s+2d
first eliminate 1 variable, lets say d ,to do this we must cancel them out, to do this multiply the top by -2 and the bottom by 3
-2 ($11.25= 3s+3d) -$22.50= -6s-6d
3 ($10.00= 4s+2d) which becomes... $30.00=12s+6d
then the -6d and the positive 6d cancel out and you are left with 1 variable
after this add the remaining parts to get...
$7.50=6s divide by 6, then put s back into one of your original equations and solve for d then you have found how much each item costs and are finished with the system of equations
I might need a little most info?
Remember that moving on the x axis is 1 and on the y axis 2
You need to simplify the question first. 2^3 is 8, 3^4 is 81, 4^5 is 1024, 6^7 is 279,936, and 9^10 is 3,486,784,401. If you multiply all of these values, you get <span>6.476775e+20. Then you can solve the 4 options you have and you'll get the answer, B.</span>
