Answer:
A) x = 12
Step-by-step explanation:
4x-6 = 42
4 = 48
x = 12
7x+10 = 94
7x = 82
x = 12
Answer:
The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.
Step-by-step explanation:
Total length of the steel = 31 inches
Let the length of the first piece = x
let the length of the second piece = y
Let the length of the third piece = z
So,
y = 2x
z = 4x + 3
x + 2x + 4x +3 = total length of the steel = 31
7x + 3 + 31
7x = 31 - 3
7x = 28
x= 4 inches
Thus; y = 2x = 2 × 4 = 8 inches
z = 4x +3 = 4×4 +3 =19 inches
∴The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.

Answer:
g(x) = -√(x -2) -1
Step-by-step explanation:
We note the domain of f(x) is x ≤ -1. The is the range of the function g(x).
The inverse function is the solution to ...
x = f(y)
x = (y +1)² +2
x -2 = (y +1)²
-√(x -2) = y +1 . . . . . . . we are interested only in the negative values
y = -√(x -2) -1
The inverse function is ...
g(x) = -√(x -2) -1
Answer:
566
Step-by-step explanation:
We can solve this equation using PEMDAS, first solving the exponent.
24^2 = 576
Now we can move onto the subtraction
576 - 3 = 573
573 - 7 = 566
