Answer:

2x^2 +11

Step-by-step explanation:

f(x) = 3x^2 +2

g(x) = x^2 -9

f(x) - g(x) = 3x^2 +2 - (x^2 -9)

 Distribute the minus sign

        = 3x^2 +2 -x^2 +9

    Combine like terms

         = 2x^2 +11

melisa1 [442]

Answer:

Step-by-step explanation:

12 men and 18 women: x1; 14 days; y1

8 men and 16 women: x2; ?; y2

12/18 simplified is equal to 2/3

8/16 simplified is equal to 1/2

This is a direct proportion, thus we can say that:

(1/2*14)/(2/3)=y2

7/(2/3)=10.5 days

I hope this helped you get out of homework trouble :D

Elina [12.6K]

Answer: 0.15p+1.59n ≤ 5.00

Step-by-step explanation:

Given: A pencil costs $0.15, and a The notebook costs $1.59.

Let p = Number of pencils.

n = Number of notebooks.

Total cost of pencil and notebook = 0.15p+1.59n

Since Mayumi has $5.00.

So, Total cost of pencil and notebook ≤ $5.00

⇒ 0.15p+1.59n ≤ 5.00

Hence, the required inequality: 0.15p+1.59n ≤ 5.00

OMG Help Me !Select all the correct answers. Which tables represent constant functions? Pick 2 and show your work. No guessing.
atroni [7]

Tables 1 and 2 because they move at a constant rate of change and they are linear functions with a slope.

Table 3 is not a function because there is more than one input for each output.

Table 4 is an exponential equation with the equation y = 4x^2

Table 5 is not a function for the same reason as table 3.
