Step-by-step explanation:
hi I have answered ur question
<h3>
Answer: D) 7</h3>
===================================================
Explanation:
a31 means "the value in the third row, first column". That value is 7
As another example, a22 = 3 since 3 is in the second row, second column.
Another example: a12 = -1 because we're in the first row and second column.
This is a 3x2 matrix due to it having 3 rows and 2 columns.
Fill in the blank with equation.
An equation is nearly the same thing as an expression. However, the dofference is that equations have an = sign while expression do not.
First solve for y
3x-y-2=1
subtract 3x from each side
-y-2=-3x+1
add 2 to both sides
-y=-3x+3
divide each side by -1
y=3x-3
To graph you could make a table:
x y
0 -3
graph that.... point and use rise over run for slope 3/1 and graph.
Your ancer is going to be around 3
