Answer:
48.95 percent (rounded)
Step-by-step explanation:
Answer: 20/3 square inches
Step-by-step explanation:
Area = length*width
length = 5 in.
width = 4/3 in.
A = 5 * (4/3) = 20/3 in^2
4(x-1)=6 you start by dividing the whole equation by 4, so
x-1=6/4 simplify, x-1=3/2 then you add 1 to the whole equation
x=1 and 3/2 or x=5/2
Answer:
x = ±(√y)/3
x = ±(√2)/3
Step-by-step explanation:
Put the given information in the given equation and solve for x:
f(x) = 2
2 = 9x^2 . . . . . use 2 in place of f(x)
2/9 = x^2 . . . . divide by 9
±√(2/9) = x . . . take the square root
x = ±(√2)/3 . . . simplify
_____
Using this as an example, we can solve f(x) = y in the same way:
y = 9x^2 . . . . use y for f(x)
y/9 = x^2 . . . divide by the coefficient of x^2
±√(y/9) = x . . . take the square root; next, simplify
x = ±(√y)/3 . . . . the equation solved for x. Note this matches the above when y=2.
