A woman went marketing for sugar for canning. In one store, sugar was 8 1/2¢ per pound and she found that she lacked 30¢ of havi
alex41 [277]
X=amount of money woman has
n=pounds of sugar 
Store #1: 8.5*n=x+30
Store #2: 8*n=x-25

multiply #2 by 17/16 to make coefficient of n same as in #1

2: 8.5*n=17/16(x-25)

Subtract #2 from #1

0=x+30-17/16(x-25)
x+30-17x/16 +25*17/16
x/16=30+25*17/16
x=480+425
=905 cents
=$9.05

What goes on the lines I don’t understand the problem
Elis [28]

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = -\frac{5}{3}x+14

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

Find the average rate of change for the function over the given interval.
jekas [21]

Answer:

The average rate of change for the function over the given integral

A(x) = \frac{e^{-2} -1}{2}

Step-by-step explanation:

Explanation

<u>Average rate of a functio</u>n:-

<u>We can define the average rate of change of a function from a to b</u>

<u></u>

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

Given function f(x) = eˣ

Given interval      x = a = -2   and y = b = 0

f(a) = f(-2) = e⁻²

f(b) = f(0) = e⁰

A(x) = \frac{e^{-2} -1}{0-(-2)}

The average rate of change for the function over the given integral
