:) Brainliest pls?

Answer:

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Step-by-step explanation:

I'll find the zeros, aka x-intercepts, and you could probably graph them.

To find the zeros, let's factor this polynomial:

r(x) = (x - 2)(x^2+7x+12)

r(x) = (x - 2)(x + 3)(x + 4)

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Find the range of the given data set. 5/8, 3/4, 1 1/8, 1 1/4 A)5/8 B)3/4 C)1 1/8

rodikova [14]

Answer:

A)5/8

Step-by-step explanation:

The range of a set of data is the difference between the highest and lowest values in the set.

Given data set:

5/8, 3/4, 1 1/8, 1 1/4

Rewriting the data set in the same denominator to compare:

5/8, 6/8, 9/8, 10/8

As we see the smallest value is 5/8 and the highest value is 10/8, so the difference:

10/8 - 5/8 = 5/8

So, the range of the given data set is 5/8

Correct choice is: A)5/8

Two trains are 500 miles apart when they first enter a collision course. If, after two hours, the distance between them is 300 m

deff fn [24]

60 miles per hour. In two miles the sum of the distance the two trains traveled was 200 miles, you divide that by 2, the sum of the speed of the two trains is 100 miles per hour, now put the speed of the slow train as x and the fast as x +20, the sum of x and x +20 is 100, so 2x + 20 =100, you subtract 20 from both sides, 2x = 80, divide by 2, x = 40, the problem asks for the speed of the fast train, so, x + 20 is 60.
