Answer:
10
Step-by-step explanation:
Since T is the midpoint of PQ, we know that PT = TQ, therefore:
3x + 1 = 5x - 5
-2x = -6
x = 3
Since PT = 3x + 1, the answer is PT = 3 * 3 + 1 = 10.
Answer:

Step-by-step explanation:
To make things easier, let's first find the equation in slope-intercept form (
where m is the slope and b is the y-intercept.
1. Find the slope:

2. Find the y-intercept by plugging in (-1,1) into the equation 

so
= 4
3. Therefore the equation of the line in slope-intercept form is 
4. To convert slope-intercept form into standard form, let's move the 3x over to the other side and divide by -1 to get rid of the negative.
Our result is
.
Hope this helps :)
Answer:
easy :) answer is 12x-8y
Step-by-step explanation:
all you do is combine like terms
1. the 10x + 2x which is 12x
2. (this part gets tricky) you have a NEGITIVE 5 minus 3 so if you are subtracting by a negitive number you add (5+3=8) and keep the negitive (-8y)
