Rus_ich [418]

Answer:

5 + 7x \le 33

Step-by-step explanation:

Given

Base\ Charge = 5

Additional = 7 per mile

Total = 33

Required

Determine the inequality

First, we need to determine the total cost for x miles.

Cost = Base\ Charge + Additional * x

Cost = 5 + 7 * x

Cost = 5 + 7x

The total cost can not exceed the amount he has, so the inequality is:

Cost \le Total

5 + 7x \le 33

blagie [28]
First figure out how many times 9 can go into 25 **do the highest amount of times it can go in-
<span><span>9x1=9 </span><span>9x2=18 </span><span>9x3=27 </span><span>9x4=<span>36
nine can go in 2 times because 3 times would be way to much
so you're mixed number would be 2
now to figure out you're numerator do 25-18=7
Now it would be 2 7/25
so you're mixed number,then the numerator,finally denomantor ALWAYS stays the same.
                *IF YOU'RE NUMERATOR AND DENOMANTOR CAN BE REDUCED THEN REDUCE</span></span></span>

larisa [96]

Answer:

\frac{dy}{dx} = - 21x^{6} + 6x² + 1

Step-by-step explanation:

Differentiate each term using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1}

Given

y = - 3x^{7} + 2x³ + x , then

\frac{dy}{dx} = (7 × - 3 )x^{6} + (3 × 2)x² + (1 × 1 )x^{0}

    = - 21x^{6} + 6x² + 1
