Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.

Simplify this expression. 12x2(3x4 − 2x)

musickatia [10]

Answer:

$36*x^6-24*x^3$

Step-by-step explanation:

We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:

$=12*x^2*(3*x^4-2*x)$

$=12*3*x^(2+4)-12*2*x^(2+1)$

$=36*x^(6)-24*x^(3)$

The answer is B

$36*x^6-24*x^3$

A bicycle tire has a radius of 10 inches. To the nearest inch, how far does the tire travel when it makes 4 revolutions?

Aloiza [94]

Answer: 251.2 inches.

Step-by-step explanation: You have to multiply 4*2*π*radius. So, simply multiply 4*2*3.14*10. It would come out as 251.2 inches.
