Answer:

<em>12.5w = 419.38</em>

<em>and</em>

<em>15.5w = 419.38</em>

Step-by-step explanation:

find the total cost of all the computer parts.

= 259.99 + 2* 39.95 + 79.49 = $419.38

Shana will save $12.50 per week and Marie will save $15.50

per week

therefore we can create two inequalities

<h2><u> Shana:</u></h2>

12.50 * w = 419.38

<em>12.5w = 419.38</em>

w = 419.38/12.5

w = 33.5504

<h2><u>Marie</u></h2>

15.50*w = 419.38

<em>15.5w = 419.38</em>

w = 419.38/15.5

w =27.0568

The table below shows how much money a grocery store receives for selling different amounts of asparagus.
Ksivusya [100]
The answer is C) $30.00. First, find out how much 1lb costs. 1lb would cost 1/4 of 4lb. $10×1/4=$2.50/1lb. So 12 pounds would be 12x the cost of 1lb. $2.50×12 pounds=$30/12lb.

Given f(x)=x^2+5 and g(x)=2x^3-1 find (f/g)(-3)
AlekseyPX

For this case we have the following functions:

f (x) = x ^ 2 + 5\\g (x) = 2x ^ 3-1

By definition of composition of functions we have:

(f / g) (x) = \frac {f (x)} {g (x)}

Then substituting:

f (-3) = (- 3) ^ 2 + 5 = 9 + 5 = 14\\g (-3) = 2 (-3) ^ 3-1 = 2 (-27) -1 = -54-1 = -55

So:

(f / g) (- 3) = \frac {14} {- 55} = - 0.25

Answer:

(f / g) (- 3) = \frac {14} {- 55} = - 0.25
