Answer:
15 yards
Step-by-step explanation:
proportion:
2/5:6/X
2x=30
x=15
Mr. Lewis | 100$
Glue = 1.50$ (x40)
Box = 0.89$ (x40)
1.50 x 40 = 60$
0.89 x 40 = 35,6$
Total spend (95,6$)
100 - 95,6 = 4,4$
Answer: 4,4$
Y= 3.11x+ 17.59
I got this equation by doing 23.81-20.70 to find m, which is 3.11.
Then to find b, or y-intercept, I subtracted 3.11 from 20.70 to get the origin all price and got 17.59
Answer:
60 squaer feet
So lets seperate the shapes one for the bottom small chunk and one for hte big long large top chunk.
To find area you do height times width. So the bottom would be 3 times 4 which is 12 square feet.
Now the top part would be 4+4+4 which is 12 then times that by 4 and get 48.
Now you add 48 and 12 and you get 60 square feet!

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
