Tell whether x and y show direct variation. x + y = 6

Over [174]

<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul

Alexandra [31]

45 million * $2^{4}$ = 45million * 16 = 720million

Or you can use
$y=Ae^{kt}$
A is equal to 45 million
To find the rate, k, we can plug in:
$90million=45million*e^{k*1}
$
$2=e^{k}$
$k=ln(2)$
$y=4.5*10^{7}*e^{t *ln2}$
Knowing that t = 4
$y = 4.5*10^{7}*e^{ln(2)*4}
$
$y = 720 million$

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

$2x-10+2x-10+3x+25=180$ <em>combine like terms</em>
