The factor (x-9) is negative for x < 9. It is zero for x = 9.

The factor (7x+2) is negative for x < -2/7.

The factors have different signs for -2/7 < x < 9. When their signs are different, their ratio is less than zero. When x = 9, the ratio is equal to zero.

The appropriate choice is the graph that shows -2/7 < x ≤ 9.

When this 3 digit number is rounded to the nearest hundred it rounds to 900. The digit in the ones is the fifth odd number you c

Vilka [71]

The first digit is 9 or 8.
The fifth odd number you count beginning with one is 9.
Let the middle number be x.
If the first number is 8, then 8 + x + 9 = 22 => 17 + x = 22 => x = 22 - 17 = 5. then the number is 859 which approximates to 900 to to the nearest hundred.
If the number is 9, then 9 + x + 9 = 22 => 18 + x = 22 => x = 22 - 18 = 4, then the number is 949, which also approximates to 900 to the nearest hundred.

Therefore, the required number is 859 or 949.

15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he

Snezhnost [94]

Answer:

$2575

Step-by-step explanation:

For this problem, we need to form an equation that represents the car salesman's weekly income. We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales. Let n represent the total amount of sales the car salesman made. So we can build the equation as follows:

f(n) = 0.025n + 700

Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.

So let's use our formula to calculate how much he made for the week given he made $75000 in sales.

f(75000) = 0.025(75000) + 700

f(75000) = 1875 + 700

f(75000) = 2575

Hence, the car salesman made $2575 for the week.

Cheers.
