Answer:

821 bacteria

Step-by-step explanation:

You have that the growth of bacteria is represented by:

y = 79.31(1.48)x

N° Bacteria=79.31(1.48)(N° Days)

If you know that N° Days is 7, you need to replace x=7 in the Equation given.

Then:

N° Bacteria=79.31(1.48)(N° Days)

N° Bacteria=79.31(1.48)(7)

N° Bacteria=821,65

What is the equation of the line that is parallel to the line 2x − y = 3 and passes through the point (2, −1)?
Ivanshal [37]

Answer:

C. y = 2x − 5

Step-by-step explanation:

Given equation of line

2x − y = 3

rewriting the equation in slope intercept form as answer are given slope intercept form

y = 2x - 3

slope intercept form of equation is

y = mx + c

where m is the slope

c is y intercept

thus

slope for y = 2x - 3 when comparing with y = mx + c is 2

now we know slope of two parallel line is same

thus,

the slope of  line that is parallel to the line 2x − y = 3

is 2

Let the equation of required line be y = mx + c

where m = 2

thus

y = 2x + c is the new required equation

it passes through the point (2, −1)

using y = -1 and x = 2 in y = 2x + c

-1 = 2*2 + c

c = -1 - 4

c = -5

thus,

equation of required line is option c

y = 2x - 5 ----answer

It would be: 11/18 - 1/6

= 11 - 3 / 18

= 8/18

= 4/9

In short, Your Answer would be Option D
