Answer:

Step-by-step explanation:

because, if y = 4 and x = 1 then it would be 4/1 or 4 just simplify.

45 POINTS!! Please help me solve this Table I’m having a hard time this is my last chance to pass!

Anettt [7]

Solution:

Given function:

f(x) = x - 1

Solution (x = -2):

f(x) = x - 1
=> -2 - 1
=> -3

Solution (x = 0):

f(x) = x - 1
=> 0 - 1
=> -1

Solution (x = 2):

f(x) = x - 1
=> 2 - 1
=> 1

Solution (x = 3):

f(x) = x - 1
=> f(x) = 3 - 1
=> 2

Enter the value for x that makes the equation -3(x-4)+x=2x true.

Norma-Jean [14]

Answer:

x = 3

Step-by-step explanation:

Simplify the equation to -3x + 12 + x = 2x, and then to -2x + 12 = 2x. Now you have to make the x values on one side so now you are left with 12 = 4x, so you just simplify by dividing 12 by 4. The answer is 3 = x.

A culture started with 3,000 bacteria. After 8 hours, it grew to 3,300 bacteria. Predict how many bacteria will be present after

Sav [38]

Answer:

$3,462\ bacteria$

Step-by-step explanation:

In this problem we have a exponential function of the form

$y=a(b^x)$

where

x is the time in hours

y is the numbers of bacteria

a is the initial value

b is the base

r is the rate of growth

b=(1+r)

we have that

$a=3,000\ bacteria$

For x=8, y=3,300

substitute in the exponential function

$3,300=3,000(b^8)$

solve for b

$1.1=(b^8)$

$b=\sqrt[8]{1.1}$

$b=1.0120$

Find the value of r

$r=b-1=1.0120-1=0.0120=1.20\%$

The equation is equal to

$y=3,000(1.012^x)$

For x=12 hours

substitute the value of x in the equation

$y=3,000(1.012^{12})$

$y=3,462\ bacteria$
