1.
The equation for this problem would be
y = (?)x + 190
With y being the height after a given amount of years and x being the amount of years passing. We would need to find ?, the rate of how fast the tree grows. The problem gives us y = 274 centimeters and x = 3 years
Let’s plug in and solve for ?
274 = ?(3) + 190
84 = ?3
28 = ?
The tree grew 28 cm per year
2.
Since we know the rate of change and y, let’s just plug in values
344 = 28x + 190
154 = 28x
5.5 = x
5.5 years since Renata moved.
The transformation is a reflection with x-axis as the axis of reflection. Reflection is a type of transformation in which the transformed image is simply a mirror image of the original shape over a line or axis of reflection.
Percentage of commission received by the salesperson = 2.5%
Amount of sales made by the salesperson = $8000
Then
The amount of commission received by the salesperson = (2.5/100) * 8000 dollars
= 2.5 * 80 dollars
= 200 dollars
So the salesperson receives a commission of $200 on the total sales made. I hope the procedure is clear enough for you to understand. You can use this method in future for solving similar problems without requiring any help from outside.
To find the amount of money Robbie made, we have to multiply his worked hours by his hourly wage.
Therefore, he earned

The third answer is correct: Robbie earned $356.125
The answer is D. The nearest hundred thousand in this case would be 6 and the next number is 5 or more, we raise it up 1.
