murzikaleks [220]

30w + 20g \geq 2400

In this equation, the number of wreaths is represented with the variable 'w', and the number of garlands is represented the equation 'g'

Since the band only has to make at least 2400, the amount of money made must be equal to or more than 2400.

Good luck!

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
salantis [7]

Answer:

work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Mama L [17]

Answer:

x can be any value, x will be the input, y will be the output.

Step-by-step explanation:

If x = 3, If x = 6, If x = 9,

y = 5x - 4

y = 5 (3, 6, or 9) - 4

y = 11, y = 26, y = 41.

These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.

<u>X (Input)  I  Y (Output)</u>

3              I  11

6              I  26

9              I  41

See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.

Hope This Helps! :)
