Answer: D. g(x)

Step-by-step explanation: since,f(x)=-x^4-2

x^4>=0 for all x so,-x^4<=0 for all x

⇒ -x^4-2<=-2 for all x

⇒ f(x)<=-2 for all x so, maximum possible value of f(x)=-2

whereas g(x)= -3x^3+2 can take values from (-∞,∞)

so, g(x) has the maximum y value

17 = 3(4x - 5)

<em><u>Distributive property.</u></em>

17 = 12x - 15

<em><u>Add 15 to both sides.</u></em>

32 = 12x

<em><u>Divide both sides by 12.</u></em>

x = 2.67. (This is your answer.)

How do i find the area for number 4?

ankoles [38]

<h3>Answer: 41 cm^2</h3>

Explanation:

Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles

The bottom rectangle has area of 4*8 = 32 cm^2
The top rectangle has area of 3*3 = 9 cm^2

The total area is therefore 32+9 = 41 cm^2

You can say "square cm" or "sq cm" in place of the "cm^2".
