The day of the 52-mile double marathon is finally here! Pepe has set the ambitious goal of averaging an 8-minute mile. Pepe fini
balandron [24]

Answer:

221 minutes

Step-by-step explanation:

His goal is 8 minutes or less for every mile during the marathon.

8 x 52 = 416

That gives him 416 total minutes to complete the marathon goal.

He already ran the first half in 195 minutes, so we do this to find the time for the other half:

416 - 195 = 221

He has 221 minutes in the second half of the marathon to meet his goal.

How do you factor this trinomial 4a^2-4a+1
ElenaW [278]

Answer:

(2a-1)(2a-1)

Step-by-step explanation:

To write the factored form, multiply a*c from the standard form ax^2+bx+c. Here it is 4*1 = 4.

Then find factors of 4 that add to b=-4.

4: 1,2,4

-2+-2 = -4

Split the middle term into -2x+-2x and factor by grouping.

4a^2-2a+-2a+1\\(4a^2-2a)+(-2a+1)\\2a(2a-1)-1(2a-1)\\(2a-1)(2a-1)

What is the equation of the following line? Be sure to scroll down first to see all answer options.
Naddik [55]

Answer:

C

Step-by-step explanation:

Since the graph hits 0 at x = 0, your y intercept is 0.

The graph is decreasing which means you have a negative slope.

They gave you a coordinate so use it to find the slope.

\frac{1-0}{-3-0} = \frac{-1}{3}

That's your slope.

C is the correct answer.
