Answer:
denoted interchange solve
Step-by-step explanation:
y= (2-x)/3 Let f(x) be denoted by y, thus y= -3x+2 Now interchange x and y, it becomes x= -3y+2 Solve for y, y= (2-x)/3 This is f^(-1) x
M•8=142 is the equation i believe
20 less than (-20) a number (n) is more than (>) twice the same number (2n)
-20+n>2n
minus n both sides
-20>n
n<-20
Answer:241
Step-by-step explanation:
Reduction in cholesterol level = 14%
Original level = 280
To find the approximate cholesterol level now , all we need do is to reduce 280 by 14% , that is we will find 86% of 280.
⇒ 86/100 x 280
= 0.86 x 280
= 240.8
≈ 241
Therefore : the approximate cholesterol level now = 241
