Answer:
No solution
Step-by-step explanation:
get rid of parentheses first by multiplying
5x-3=4x+8+x
combine like terms
5x-3=5x+8
-3=8

Answer:</h3>
- Find the composite of the functions
- x/3
- All the answers are correct
- f(x) = 2+∛(x/3)
- f(x) = (x+3)/2
<h3>
Step-by-step explanation:</h3>
1. If f(x) and g(x) are inverse functions, then f(g(x)) = g(f(x)) = x. Finding the composite of the two functions will tell you if they are inverses.
2. To find the inverse of a function, swap x and y, then solve for y.
... x = 3y
... x/3 = y . . . . . matches f(x) = x/3
3. A function will pass the vertical line test. If its inverse is also a function, that, too, will pass the vertical line test. Since the inverse of a function is that function reflected across y=x, any inverse function that passes the vertical line test corresponds to an original function that passes the horizontal line test. (A vertical line reflected across y=x is a horizontal line.)
4. See 2.
... x = 3(y -2)³
... (x/3) = (y -2)³ . . . . divide by 3
... ∛(x/3) = y -2 . . . . .take the cube root
... 2+∛(x/3) = y . . . . .add 2
... f(x) = 2+∛(x/3) . . . . is the inverse
5. See 2.
... x = 2y -3
... x+3 = 2y . . . . . add 3
... (x+3)/2 = y . . . .divide by 2
... f(x) = (x+3)/2 . . . . is the inverse
Answer:
Lee has more pizza
Lee has 2.24 in^2 more than John
Step-by-step explanation:
step 1
Find the area of each slice of pizza
we have
----> the radius is half the diameter
substitute
step 2
Find the area of John's part (area of shaded triangle)
The measure of the central angle of each slice of pizza is equal to
so
the height of triangle is equal to the base
Let
x ---->the base of the shaded triangle
Remember that
substitute
solve for x
Find the area of shaded triangle
step 3
Find the area of Lee's part
The area of Lee's part is equal to the area of two slices of pizza minus the area of two triangles
so
assume
so
Lee's part is greater than John part's
Find the difference
therefore
Lee has more pizza
Lee has 2.24 in^2 more than John
