True or false (if it's false, replace the words in parentheses with the correct answer):
Elis [28]

Answer:

1 is true , 2 is false

Step-by-step explanation:

for equation 2

-2x<8

-2x=8

then we divide both side by coefficient of x which is -2

-2x/-2=8/-2

we will be left with

x= 8/-2

x=-4 which shows that x<-4 and it differs from the second inequality

plz help !! write two real world situations that you can model using the exponential function f(x)=2 to the power of x
Margaret [11]

Answer:

Two real world situations are shown below.

Step-by-step explanation:

Initial population of a certain bacteria is 1 thousand and the population doubles in each hour. So, population of bacteria (in thousands) after x hours is

f(x)=1(2)^x

f(x)=(2)^x

A person invests 1 lakh rupees in shares and the amount is twice at the end of each year. So, total amount (in lakhs) after x years is

f(x)=1(2)^x

f(x)=(2)^x

The sum of two numbers is twice their difference. the larger number is 6 more than twice the smaller. find the numbers.
soldi70 [24.7K]
Let the numbers be x and y; x being the larger number and y being the smaller.

Given,
 
x + y = 2* (x - y)

x + y = 2x - 2y

x = 3y

Also given,

x = 6 + 2y

3y = 6 + 2y

--- y = 6

Thus, x = 3y = 3*6 = 18.

Therefore, the numbers are 18 and 6.
