Factor the polynomial: 2x3 + 16 Question 15 options:

Mathematics
1 answer:
SOVA2 [1]3 years ago
4 0

Answer:

B

Step-by-step explanation:

Given

2x³ + 16 ← factor out 2 from each term

= 2(x³ + 8) ← x³ + 8 is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²) , then

x³ + 8

= x³ + 2³

= (x + 2)(x² - 2x + 2²)

= (x + 2)(x² - 2x + 4)

Then

2x³ + 16 = 2(x + 2)(x² - 2x + 4) ← in factored form → B

Graph the solution set.-10x≤2y
vagabundo [1.1K]

To be able to determine the graph of this inequality, we'll start rearranging the inequality putting the "y" variable at the left side of the equation.

\begin{gathered} -10x\leq2y \\ \frac{-10x}{2}\leq\frac{2y}{2} \\ -5x\leq y \\ or \\ y\ge-5x \end{gathered}

Since the inequality here is greater than or equal to, this means that the shade is above the solid line.

This equation also has a slope of -5 and y-intercept of 0.

Therefore, the graph of this equation looks like this:

Sam paid $55 for an hour of tutoring on Mondays and $95 for two hours on Tuesday. The hourly rate is $ per hour.The initial fee
Likurg_2 [28]

To find the hourly rate, we can subtract the cost of two hours by the cost of one hour:

m=95-55=40

So the hourly rate is $40.

Then, to find the initial fee, we subtract the cost of one hour by the hourly rate:

b=55-40=15

So the initial fee is $15.
