The average is 4 3/4 km.

you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.

5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19

19 (the total distance ran) divided by 4 (the number of days) = 4 3/4

Can someone plz help me on this problem.....

Answer:

choice 1) 2-4y

Step-by-step explanation:

from the answers available, you are looking for the expression for x to substitute into the first equation.

The second equation is: x+4y = 2

To convert x+4y = 2

subtract 4y from both sides of the equation:

x+4y-4y = 2-4y

simplified:

x = 2-4y

CalculatorIn the coordinate plane, what is the length of the line segment that connects points at (4, -1) and (9, 7)?Enter your
andre [41]

The formula to calculate the distance between two points is given by

d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

In this problem, we have the coordinates

(4, -1) and (9, 7)

substitute in the formula

\begin{gathered} d=\sqrt{(7+1)^2+(9-4)^2} \\ d=\sqrt{8^2+5^2} \\ d=\sqrt{89} \\ d=9.43 \end{gathered}<h2>The answer is 9.43 units</h2>

Which answer choice states the range of the following
ankoles [38]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.

Remember that for any relation, we have a set A that matches the the domain (also called the set of inputs) of the function and the set B that contains the range (also called the set of outputs).

Suppose our relation is:

y=-10+x \\ \\ For \ x=1,2,3,4,5

So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:

\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5

So in this context, the correct option is:

B) (-9,-8, -7, -6, -5}
