We know that
in the matrix T the element t(13) refers to the element in row 1 and column 3
therefore
the answer is 7

What scale is used on the graph

b). 2 cm to 2 units on both axes
As we can se there is gap of 2 boxes (side length= 1cm of one box so 2 boxes side length= 2cm) between 2 units so we can conclude that scale is equal to 2 cm to 2 units on both axes

IT IS THE RELATIONSHIP BETWEEN THE UNIT USED AND ACTUAL VALUE ON THE GRAPH
Answer:
n=-1
Step-by-step explanation:
-8n+4(1+5n)=-6n-14
-8n+4+20n=-6n-14
12n+4=-6n-14
12n+6n=-14-4
18n=-18
Answer:
35
Step-by-step explanation:
37 + x = 72
x = 72 - 37
x = 35
Step-by-step explanation:
2x + 5 = 19; X = 7: Correct
2(7) + 5 = 19
14+5=19
3+x+2-x=16; x=3 : Incorrect
3+3+2-3=16
6+2-3=16
7-3=16
4=16
x+2/5=2; x = 8: incorrect
8+2/5=2
x= 8/5
6 = 2x -8; x = 7: correct
6 = 2(7) -8
6 = 14-8
14 =1/3x+5; x = 18: Incorrect
14 = 18/3+5
14 = 6+5
