Answer:

option c, (\frac{-1}{2})x^{4} -x^{3} +x +2.

Step-by-step explanation:

Given : graph.

To find : which of the functions below could have created this graph.

Solution : We see from the graph both end point are below

By the End Behavior of the function : if the degree of  polynomial is even and leading coefficient is negative then the both end point of graph would be below.

We can see from option c , it has degree = 4 (even) and leading coefficient is negative.

Therefore, option c, (\frac{-1}{2})x^{4} -x^{3} +x +2.

Salsk061 [2.6K]

<u>Step 1: Assign variable for the unknown that you need to find. </u>

Let ' t ' be the number of hours it took for the pedestrians to meet.

<u>Step 2: List the give details</u>

Speed of first pedestrian = 4 km/hr.

Speed of second pedestrian = 6 km/hr.

Distance between two pedestrians = 27 km.

<u>Step 3: Set up an equation</u>

The relationship between speed, distance and time is given below:

Distance= \; Rate \times Time

The first one walked 4 km per hour, distance traveled by first pedestrian is given below:

Distance_{1^{st} \; pedestrian} \; = \; 4t\\\\Distance_{2^{nd} \; pedestrian} \; = \; 6t

Two pedestrians simultaneously left two villages 27 km apart and walked toward each other.

Distance_{1^{st} \; pedestrian} +Distance_{2^{nd} \; pedestrian} =27\\\\4t+6t=27\\Combine \; Like \; Terms\\\\10t=27\\Dividing \; 10 \; on \; both \; sides\\\\ \frac{10t}{10}  = \frac{27}{10}  \\Simplifying \; fraction \; on \; both \; sides\\\\t=2.7 \; hours

Conclusion:

The pedestrian meet after 2.7 hours.

Help plzz (30) points for both of the question-plz help - this is life or dead answer
Elodia [21]

Answer:

The answer is B) 11.

Step-by-step explanation:

We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):

2.3x + 4.3 + 0.4 = 30

2.3x + 4.7 = 30

2.3x + 4.7 - 4.7 = 30 - 4.7

2.3x = 25.3

2.3x/2.3 = 25.3/2.3

x = 11

Find the slope of the line shown on the graph to the right (-4,-3) and (2,3)
DerKrebs [107]

Answer:

y=x+1

Step-by-step explanation:

to do this we have to use the slope formula, Rise/Run which is (y2-y1)/(x2-x1) so (3-(-3) or 3+3 divided by (2-(-4) or 2+4, so the slope would be 6/6 or 1. so it is up one over one, and since at the x coordinate of 0 it is y=1 we know the formula must be y=x+1
