btw -_- I've gotten them all right the way here I know it looks like I'm stupid but fr I been keepin up lately anyways lol plz answer with explanation I have trouble with these ones

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.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
