Answer:

1) Inequality: 110x>150+85x

2) Solution: x>6, then Nadia would need to sell more than 6 ads per week in order for Choice A to be the better choice,


<u>Solution:</u>

Be x the number of ads Nadia sells

A) Choice A: $110 for each ad she sells. She would earn:

Ea=110x

B) Choice B: A weekly salary of $150, plus $85 for each ad she sells. She would earn:

Eb=150+85x

1) Write an inequality to determine the number of ads Nadia would need to seel per week in order for Choice A to be the better choice:

Ea>Eb

110x>150+85x

2) Solution

Solving for x: Subtracting 85x both sides of the equation:

110x-85x>150+85x-85x

Subtracting:

25x>150

Dividing both sides of the equation by 25:

25x/25>150/25

Dividing:

x>6

Simplify the expression c^-6 * d^4/ c^-16 * d^14​
Naily [24]

Answer:

\dfrac{c^{10}}{d^{10}}

Step-by-step explanation:

Although the way you wrote problem, this is not what it looks like, I think this is what you meant.

\dfrac{c^{-6} \times d^{4}}{c^{-16} \times d^{14}} =

= \dfrac{c^{-6}}{c^{-16}} \times \dfrac{d^{4}}{d^{14}}

= c^{-6 - (-16)} \times d^{4 - 14}

= c^{-6 + 16} \times d^{-10}

= c^{10} \times d^{-10}

= \dfrac{c^{10}}{d^{10}}

Does 17/10 and 12/5 form a proportion?
ki77a [65]

Answer:

No

Step-by-step explanation:

17/10 is not proportional to 12/5. Proportional relationships are relationships between two variables where their ratios are equivalent.  17/10 as a ratio is 17:10 and 12/5 as a ratio would be 12:5. A proportional relationship for 12/5 would be 24/10.

Hope this helps :)

Help! What is the average rate of change of f(x)=x^2+3x+6 over the interval -3 less-than-or-equal-to x less-than-or-equal-to 3?
Makovka662 [10]

Answer:

The average rate of change of the function over the interval is 5.

Step-by-step explanation:

Average rate of change of a function:

The average rate of change of a function f(x) over an interval [a,b] is given by:

A = \frac{f(b)-f(a)}{b-a}

Interval -3 less-than-or-equal-to x less-than-or-equal-to 3

This means that a = -3, b = 3

f(x) = x^2 + 3x + 6

So

f(b) = f(3) = (3)^2 + 3(3) + 6 = 9 + 9 + 6 = 24

f(a) = f(-3) = (-3)^2 + 3(-3) + 6 = 9 - 9 + 6 = 6

Average rate of change

A = \frac{f(b)-f(a)}{b-a} = \frac{24+6}{3-(-3)} = \frac{30}{6} = 5

The average rate of change of the function over the interval is 5.
