Timothy is going to the store to buy balloons. Large balloons cost $7.80 each and small balloons cost $2.25 each. He has $75 to spend. Which inequality shows all possible combinations of large balloons, x, and small balloons, y, that Timothy can purchase?

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

its line 2 i just added the rest or else it wouldn't let me answer

image for option 4

step-by-step explanation:

i just know the internet

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
