Fittoniya [83]3 years ago

For the book store, it is a discreet graph. Every book is a case by itself, no event is dependent on the other. So now variable is dependent on another.
The swimming pool case, the time is the independent variable in the function where the water volume changes with respect to time. So it it has a continuous graph.

Hope this helps.

You are selling tickets to a play. You have sold (3t+2) tickets for $5 each and (2t+5) tickets for $7 each. Write an expression
aliya0001 [1]

Given that the number of tickets that are sold for $5 is (3t+2) tickets.

The number of tickets that are sold for $7 is (2t+5) tickets.

We need to determine the expression that represents the total number of tickets sold and the simplified expression.

<u>Total number of tickets sold:</u>

The expression for (3t+2) tickets sold for $5 is given by

5(3t+2)

The expression for (2t+5) tickets sold for $7 is given by

7(2t+5)

The expression for the total number of tickets sold is given by

5(3t+2)+7(2t+5)

Thus, the expression that represents the total number of tickets sold is 5(3t+2)+7(2t+5)

<u>Simplified expression:</u>

We need to simplify the expression 5(3t+2)+7(2t+5)

Hence, let us multiply the terms within the bracket.

Thus, we get;

15t+10+14t+35

Adding the like terms, we have,

29t+45

Thus, the simplified expression is 29t+45

Please help this is important<br> -1.5x+12=2.5x-12
Anna35 [415]

Answer:

x = 6

Step-by-step explanation:

move all terms to the left:

-1.5x+12-(2.5x-12)=0

get rid of parentheses

-1.5x-2.5x+12+12=0

add all the numbers together, and all the variable.

-4x+24=0

move all terms containing x to the left, all other terms to the right

-4x=-24

x=-24/-4 - divide

x=+6

schepotkina [342]
Given:

A rectangular piece of cloth (dimensions):

L = length of the rectangle
W = width of the rectangle

The area of the rectangle is:

A = L x W

If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:

 A (one sail) = 1/2 (L x W) <span />
