Can I have some help with this? Construct a linear function that has a slope of -3 and passes through the point (-2,3).

Arisa [49]

Answer:

-3x-3

Step-by-step explanation:

We want our equation to look like this

y=mx+b

we know that m= -3 so we just need to find b

We can start by plugging in the ordered coordinates into our equation

3=(-3)(-2)+b

Solve for b

3=6+b

b= -3

Which means our final equation is

y= -3x-3

Question 28 of 30Calculate the surface area in square feet of a box that measures 13 inches inlength, 11 inches in width, and 11

KATRIN_1 [288]

ANSWER:

5.65 ft²

STEP-BY-STEP EXPLANATION:

We have the following measures:

Length (l) = 13 inches

Width (w) = 11 inches

Height (h) = 11 inches

We can determine the surface area as follows:

$\begin{gathered} A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \\ \text{ We replacing:} \\ \\ A=2(13)(11)+2(13)(11)+2(11)(11) \\ \\ A=286+286+242 \\ \\ A=814\text{ in}^2 \\ \\ \text{ Convert inches to feet, knowing that 1 foot is equal to 12 inches} \\ \\ A=814\text{ in}^2\cdot\frac{(1\text{ ft\rparen}^2}{(12\text{ in\rparen}^2} \\ \\ A=5.65\text{ ft}^2 \end{gathered}$

Therefore, the correct answer is 5.65 ft²
