Answer:

16y

Step-by-step explanation:

$-(4x - 8y) + 4x + 8y$

Use order of operation to simplify the given expression

Lets start with simplifying the parenthesis

Multiply negative sign inside the parenthesis

$-(4x - 8y) + 4x + 8y$

$-4x + 8y+ 4x + 8y$

Now we combine like terms. Combine the terms that has same variables

$-4x + 8y+ 4x + 8y$

$16y$

F(x)= if -1 < x < 1<br> if 3 < x < 5

blsea [12.9K]

Answer:

(x−4)²+(y)²=1

Step-by-step explanation:

If you translate this into English, you get something like this:

The y value lies between -1 and 1, if the x value is between 3 and 5, This could very well be a circle with the center point M and a radius of 1.

The x-coordinate of the middle lies between 5 and 3, which is 4

The y-coordinate of the middle lies between -1 and 1, which is 0.

So the middle is (4 , 0) and radius is 1

The circle equation (xa) 2 + (yb) 2 = r 2

The circle with center M( a b ) and radius r has as a comparison:

(x - a)² + (y - b)² = r²

with a = 4 and b = 0 and r = 1

(x − 4)² + (y - 0)² = 1²

(x−4)²+(y)²=1

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

$m =\frac{y_2 - y_1}{x_2 - x_1}$

Pick any two corresponding points from the table

So, we have:

$(x_1,y_1) = (8,1.21)$

$(x_2,y_2) = (12,1.63)$

So:

$m =\frac{y_2 - y_1}{x_2 - x_1}$

$m =\frac{1.63 - 1.21}{12 - 8}$

$m =\frac{0.42}{4}$

$m =0.105$

The linear equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y = 0.105 * (x - 8) + 1.21$

Open bracket

$y = 0.105x - 0.84 + 1.21$

$y = 0.105x + 0.37$

To get the length closest to 4.2lb,

we set $y = 4.2$

Then solve for x

So, we have:

$y = 0.105x + 0.37$

$4.2 = 0.105x + 0.37$

Collect like terms

$0.105x= 4.2 - 0.37$

$0.105x= 3.83$

Solve for x

$x= 3.83/0.105$

$x\approx 36.5$

Liono4ka [1.6K]

Answer:

$362.25

Step-by-step explanation:

Profit made per product :

Soft pretzel = $5.25 - $3.50 = $1.75

Candied apple = $3.50 - $1.75 = $1.75

For every 2 candied apple sold, 7 soft pretzel is sold :

If 161 sold pretzel is sold, the number of candied apple sold will be :

(161 / 7) * 2

23 *. 2 = 46 candied apple was sold

Profit made on product sold :

Soft pretzel = $1.75 * 161 = $281.75

Candied apple = $1.75 * 46 = $80.5

$(80.5 + 281.75) = $362.25
