Answer:

  x = {-9, -4, -3/2}

Step-by-step explanation:

The zeros are the values of x that make the factors zero. (If a factor is zero, the product will be zero.)

<u>x+4 = 0</u>

  x = -4 . . . . subtract 4

<u>2x+3 = 0</u>

  2x = -3 . . . . subtract 3

  x = -3/2 . . .  divide by 2

<u>-x-9 = 0</u>

  -9 = x . . . . add x

__

The zeros are ...

  x = {-9, -4, -3/2}

Answer and show all of your work.
quester [9]

Answer:

105 shifts

Step-by-step explanation:

Hourly net rate of pay = $12

1 shift = 8 hours

⇒ net pay per shift = $12 × 8 = $96

Total cost  = tuition + residence + books

                  = $4500 + $4800 + $700

                  = $10,000

To calculate how many shifts Joanne needs to work, divide the total cost by the pay per shift and round it up:

Number of shifts = total cost ÷ net pay per shift

                            = $10,000 ÷ $96

                            = 104.1666666...

                            = 105 shifts

<u>Note</u>: we need to round up, as if Joanne works 104 shifts, she will earn $9,984 which is not quite enough to pay for tuition, residence and books.

If x varies directly as y, find x when y=8. x=11 when y=-3
andriy [413]

Answer:

x=-\frac{88}{3}

Step-by-step explanation:

When a quantity "A" varies DIRECTLY with another quantity "B", we can write the proportionality equation as:

A = kB

Where k is the proportionality constant (to be found)

In this problem, it is given x varies DIRECTLY with y, so we can write:

x = ky

Also, given, x = 11, y = -3, so we plug these into the equation and first find k:

x = ky

11 = k(-3)

k = -11/3

Now, we need to find x when y = 8, so we substitute and find x:

x=ky\\x=(-\frac{11}{3})(8)\\x=-\frac{88}{3}
