(0.20)3 (0.80)
(0.80)3 (0.20)
0.20

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
