Slope = (y2 - y1) / (x2 - x1)
(0,4)...x1 = 0 and y1 = 4
(-8,-1)...x2 = -8 and y2 = -1
now we sub and solve
slope = (-1 - 4) / (-8 - 0) = -5/-8 = 5/8 <=
23.99×.22=5.277 round to to 5.28
23.99-5.28= 18.71 sale price
It'll be 8 |a^3|.
we don't use modulus on 8 cuz it is obviously positive but we do not know about a^6 when rooted it can be +ve or -ve.
We know that
[area of <span>Martha's bathroom]=5*7-----> 35 ft</span>²
[area of one tiles]=(1/4)²-----> 1/16 ft²
if 1 tile has area of--------------> 1/16 ft²
x tiles---------------------------> 35 ft²
x=35/(1/16)-----> x=35*16-----> x=560 tiles
the answer is
560 tiles
