Hello,
I suppose you mean -1! else f(x)=f^1(x)
y=x²-81
-> x=y²-81 (exchahge x and y)
->y²=x+81 (solve for y)
It is because (f^-1)(x) is not a function!
with x>=-81
<span>Let l equal the length of the rectangle
</span><span>width of a rectangle is 10 mm shorter than its length
</span>
<span>a. Write an expression for the width in terms of the length?
</span> w = l - 10
<span>b. Write an equation for the perimeter in terms of l.
P = l + l + (l-10) + (l-10)
P =4l - 20
</span><span>c. Solve the equation, clearly indicating the length of the rectangle.
</span> P =4l - 20
244 = 4l - 20
4l = 244 + 20
4l = 264
l = 284/4
l = 66
<span>d. Solve for the width of the rectangle. Clearly indicate the width of the rectangle.
</span>w = l - 10
w = 66 - 10
w = 56
Answer:
only construction
Step-by-step explanation:
it must have 4 sides
Answer:
1/8
Step-by-step explanation:
Given that:
Fraction shared = 1/2
Number of people = 4
Fraction shared / Number of people
1/2 ÷ 4 = 1/2 * 1/4 = 1/8
Fraction of the whole meat each got = 1/8
