Step-by-step explanation:
Answer:
105
Step-by-step explanation:
It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
(91+89+X)/3 =95
91+89+X =95*3
180+X =285
X =285 - 180
=105
Answer:
X = -3. non-extraneous
Step-by-step explanation:
The given equation is 
We cross multiply to get:
Expand and multiply.
We factor to obtain:
Checking for extraneous solutions
Substitute x=-3 
.....Non-extraneous
Checking for x=6
....Non-extraneous
Y-4= -3(x-3)
First you'll distribute the -3(x-3) and you should get -3x+9 (a negative divided by a negative is a positive)
So your new equation will be y-4=-3x+9. Next you'll get rid of the -4 y adding 4 on both sides of the equation. So you should get y=-3x+13. So points you could use is <span><span>(<span>0,13</span>)</span>,<span>(<span>1,10</span>)</span>,<span>(<span>2,7</span>)</span></span><span />
