Answer:

p = 23       and p = -22

Step-by-step explanation:

| 2p -1 | =45

Absolute value equations have 2 solutions, one positive value and one negative

2p-1 = 45    and 2p-1 = -45

Add 1 to all sides

2p-1+1 = 45+1    and 2p-1+1 = -45+1

2p = 46                        2p = -44

Divide by 2

2p/2 = 46/2    and   2p/2  = -44/2

p = 23       and p = -22

Answer:

p = 23

p = - 22

Step-by-step explanation:

Because of the special brackets, we know that this is a equation with absolute values, which means that it has 2 answers; here you go:

2p - 1 = 45  

2p = 45 + 1

p = 46/2

p = 23  

2p - 1 = - 45

2p = - 45 + 1

2p = - 44

= - 44/2

p = - 22

Hope this helps, and please mark me brainliest if it does!

If a point (-3/5,b) is on the graph of the equation 2x+3y=6 and also on the graph of y=x+3, what is the value of b?
AleksAgata [21]
Since the point satisfies the equation
&nbsp; y = x +3
you have
&nbsp; b = (-3/5) +3 = 12/5 . . . . . . . matches A. 12/5
