Answer:
f(x)^-1 = 
Step-by-step explanation:
f(x) = (4x - 3) / 7
y = (4x - 3) / 7
x = (4y - 3) / 7
x / 7 = 4y - 3
x/7 + 3 = 4y
y =
Answer:
2
Step-by-step explanation:
0(162/3125)+1(162/625)+2(216/625)+3(144/625)+4(48/625)+5(32/3125)
= 2
For finding the perimeter of abc (triangle), we MUST need the two others coordinates of b and c
let b(1, 2) and c (2, -4)
we need to calculate the distances ab, ac, and bc
vector (ab)=(1-(-2), 2-9)=(3, -7), so its length is ab=sqrt(3²+ (-7)²)=7.61
realising the same method, we find bc=6.08, ac=13.60
so the perimeter of abc is P= ab+bc+ca=13.60+6.08+7.61=27.29
The answer is a - yes, because of the associative property
Answer:
a) 3/16
b) 8/7
Step-by-step explanation:
i think the idea there was just simplifying the fractions.
