Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.
<h3>What is a function?</h3>
In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.
In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.
By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).

Answer:
16
Step-by-step explanation:
A square has same length on all sides.
So, 18x-20=42-13x
18x+13x=42+20
31x=62
x=62/31=2
Now you can substitute x=2 in one of the equations to find the length of the side.
18x-20 = (18*2)-20 = 36-20 = 16
Answer:
10 different possible scores
Step-by-step explanation:
the total possible scoring combinations are:
<u>large bin (1)</u> <u>medium bin (5) </u> <u>small bin (10)</u> <u>score</u>
3 0 0 3
2 1 0 7
2 0 1 12
1 2 0 11
1 0 2 21
1 1 1 16
0 3 0 15
0 2 1 20
0 1 2 25
0 0 3 30
In the back of your statistics text, there is a table labeled something like "areas under the normal distribution." Look for the portion values for the longer or smaller portion to get your Z score.
I really hope this helps you :)
B2-4ac tells you whether a quadratic can be factored. If you get a perfect square number then the quadratic can be factored. If you don't then the quadratic cannot be factored. b2 - 4ac = 6 squared - 4(4)(2)= 36-32 = 4 which is a perfect square so 4x2+6x+2 can be factored.
