An employee produced 9/2 widgets in 1/6 hour .how many widgets does she produce per hour

puteri [66]

To get her output per hour, you will have to divide her output by the time she took to produce it (in hour)

So per hour she would produce:

9/2 ÷ 1/6 = 9/2 x 6 = 27

The answer is 27 widgets per hour

Which statement must be true? a b c d

lozanna [386]

ANSWER

$\boxed {m \ne0}$

EXPLANATION

The given function is

$f(x) = mx + b$

We need to find the inverse of this function,

Let

$y= mx + b$

We interchange x an y to obtain,

$x = my + b$

We solve for y now to obtain,

$x - b = my$

We divide through by m to get,

$\frac{x - b}{m} = y$

Hence the inverse function is ,

${f}^{ - 1} (x) = \frac{x - b}{m}$

For this inverse to exist, the denominator must not be equal to zero,

Thus

$m \ne0$

The correct answer is A.

This is the same as the last question you asked. 63 + 61 = 124. 180 - 124 = 56. Angle ACB is 56 degrees.
