Write a slope-intercept form of the equation if it passed the

inna [77]

Answer:

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Step-by-step explanation:

We need to write the slope intercept form of the equation which passes through (4,-1) and parallel to the line y = -3/4x .

We know that the line parallel to a given line has the same slope . Therefore the slope of the line will be , ( on comparing to Slope Intercept Form ) .

$\sf\longrightarrow Slope =\dfrac{-3}{4}$

On using point slope form ,

$\sf\longrightarrow y-y_1= m ( x - x_1)$

Substitute the respective values ,

$\sf\longrightarrow y - (-1) = \dfrac{-3}{4}( x - 4 )$

Simplify ,

$\sf\longrightarrow y +1 = \dfrac{-3}{4}x + 3$

Multiply both sides by 4 ,

$\sf\longrightarrow 4y + 4 = -3x + 12$

Put all terms on same side , i.e. on LHS ,

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Hence the equation of the line is 3x + 4y - 8 = 0.

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be re

Assoli18 [71]

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

$p=2^d$

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
