<u>Answer:</u> Greta is correct.

<u>Explanation:</u>

Greta is correct sine you can substitute different number of people for each of the values of and y and check that each person will still plant 4 trees.

For example:

4x = 4(1) = 4 trees; and

4 x 5 = 20

but you should follow a certain pattern to increase the value of x, such that every foe every value of x, one person is able to plant 4 trees.

The table shows a linear function.
dem82 [27]

Answer:

see explanation

Step-by-step explanation:

A linear equation in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula using any 2 points from the table.

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (10, - 1) and (x₂, y₂ ) = (5,2)

m = \frac{2+1}{5-10} = \frac{3}{-5} = - \frac{3}{5}

Note the point (0, 5) is on the y- axis → c = 5

y = - \frac{3}{5} x + 5 ← equation representing the function

Natalka [10]
We can use the fundamental counting theory to determine the number of possible ways in which a 5-digit can be assigned from zero to four. In this case, the first to fifth digit can be assigned from zero to four. Hence the sequence is 5*5*5*5*5 equal to D. 3125
