Answer:
(- 6, 6 )
Step-by-step explanation:
Assuming the centre of dilatation is the origin, then
The coordinates of the image points are 3 times the original points
B = (- 2, 2 ), then
B' = ( 3 × - 2, 3 × 2 ) = (- 6, 6 )
<span>Let +a+ = number of trumpet players
Let +b+ = number of saxophone players
---------------------
(1) +a+=+b+-+10+
(2) +b+=+3a+
----------------
Substitute (2) into (1)
(1) +a+=+3a+-+10+
(1) +2a+=+10+
(1) +a+=+5+
and
(2) +b+=+3%2A5+
(2) +b+=+15+
------------------
There are 5 trumpet players
and 15 saxophone players</span>
Answer:
h = 3v/b
Step-by-step explanation:
Here, we want to select the equation that solves for h
What this simply means is that we should make h the subject of the formula
Thus, we have 3 * v = bh
3v = bh
h = 3v/b
Answer:
3
Step-by-step explanation:
It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
