Calling card A charges a connect fee of 69e plus 1.9c/minute. Calling card B has no connect fee but charges 6e/minute. Which system of equations can be used to determine the number of minutes (x) where the price (y) is the same for both cards?
y = 1.9x + 69
ОА
y=6x
OB.
y = 6x + 69
y = 1.9x
y 6x + 69
1.9 mx
D
69 - 1.9x + y
0 6x + y
ОЕ.
y 69x + 1.9
y = 6

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

if i put something wrong your not gonna like it so rather not say nothing.

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
