Answer:
9x
Step-by-step explanation:
X is an unknown variable so just leave x as it is
Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things
Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.
It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.
2+7=9 therefore your answer should be 9x
Answer:
<3 and <11
Step-by-step explanation:
A scatter plot (also called scatterplot, scatter graph, scatter chart, or scatter diagram) is a type of plot or mathematical diagram using Cartesian coordinates to display values. For typically two variables for a set of data. Is the points are coded (color/shape/size), one additional variable can be displayed. The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the verticals axis.

Answer:
18500 is the initial value
Every year they increase by a factor of 1.03
Step-by-step explanation:
This is written in the form
y = ab^x where a is the initial value and b is the growth rate/decrease
y = (18500) (1.03)^t
The initial value is 18500
The students will increase by 1.03 - 1 = .03
The factor of increase is what they multiply by which is 1.03
