<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.

Okay, so this is exponential. The formula for the exponental function is Y=ab^x

a is the y-intercept

b is the rate/ratio

x is the time

According to the graph, (remember the y-intercept is in the y-axis) so 2 is the y-intercept.

Knowing what the y-intercept is, you know what the answer is.

A.

Nadusha1986 [10]

Answer:

  • x = 40°

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

<u>Then we have following equation to solve for x:</u>

  • x + 60° + 80° = 180°
  • x + 140° = 180°
  • x = 180° - 140°
  • x = 40°
