Which of the following points lies on the graph of this equation? 2y=x+3
Dimas [21]
Since you didn't provide the points, we can't find the exact answer. However, I can explain how to do the problem for you.

To test the point, just plug in the x and y values and see it the statement is true or false.

Let's try: (3, 4)

Plug in the points and evaluate:

2(4) = 2 + 3
8 = 6
FALSE

Since this is a false statement, then the point is not on the line.

The perimeter of a rectangular field is 372 yards. If the width of the field is 87 yards, what is its length?__yards
worty [1.4K]

ANSWER

The length of the rectangular field is 99 yards

EXPLANATION

Given information

The perimeter of a rectangle field is 372 yards

The width of the field is 87 yards

To find the length of the rectangular field, follow the steps below

Step 1: Write the formula for finding the perimeter of a rectangular field

\begin{gathered} \text{ The perimeter of a rectangular field = 2\lparen l + w\rparen} \\ \text{ where l =length, and w = width} \end{gathered}

Step 2: Substitute the given data into the formula in step 1

\begin{gathered} \text{ Perimeter = 2 \lparen l + w\rparen} \\ \text{ Perimeter = 372 yards} \\ \text{ width = 87 yards} \\ \text{  372 = 2\lparen l + 87\rparen} \\ \text{ Divide both sides by 2} \\ \text{ }\frac{372}{2}\text{ = }\frac{2}{2}(l\text{ + 87\rparen} \\ 186\text{ = l + 87} \\ \text{  subtract 87 from each sides of the equation} \\ \text{ 186 - 87 = l + 87 - 87} \\ \text{  99 = l} \\ l\text{ = 99 yards} \end{gathered}

Hence, the length of the rectangular field is 99 yards

Choose the function that the graph represents.<br> Click on the correct answer.
Lynna [10]

Answer:

y=log_2 (x)

Step-by-step explanation:

We see that the graph passes though the point (2,1). So we can write:

log_a (2) = 1  => a = 2

So it's a log in base 2.
