Because this expression can actually be written as x (4x-10)(4x-10)(4×-10)

Yes, it does. A good way to fill another 6 characters is with a "please".

Watch carefully:

You have said that 2x - 5 = 7

Add 5 to each side: 2x = 12

Divide each side by 2: x = 6 .

Answer:

36.5 inches

Step-by-step explanation:

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

$x= 3.83/0.105$

$x\approx 36.5$

Hey there,

Question : In which of the scenarios below can you reverse the dependent and independent variables while keeping the interpretation of the slope meaningful

Answer :I have come across this question before.. So I know the answer :D
As the time spent swimming increases, the number of calories burned in the body increases.

Hope this helps :))
