Surely not;
5a+a-9b-6b
6a-15b
So,
5a-9b+a-6b=6a-15b
It's not equal to 6a-15
Answer:
<h2><em><u>
.1etc</u></em></h2>
Step-by-step explanation:
It would be 16 divided by 3 and from the answer you get from that you should divide it by itself equaling infinite .111111111111etc
Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY = 
with x = 22, y = 20, z = 18
cosY = 
= 
= 
, then
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
Answer:
See below
Step-by-step explanation:
Domain: set of x values
Range: set of y values
Function: no two x values are the same
Line 1:
Domain: {3, 4, 5}
Range: {1, 2, 3, 4}
Function: no since there are two points with x-coordinate 3
Line 2:
Domain: {-1, -2, 1, 2}
Range: {1, 3}
Function: yes since all x-coordinates are different
Line 3:
Domain: {-2, -1, 0, 1, 2}
Range: {0, 1, 4}
Function: yes since all x-coordinates are different
