-2 + 3b = 5b - 2(2b + 3)  Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6        Combine like terms
-2 + 3b = b - 6                 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6       Combine like terms
-2 + 2b = -6                      Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2          Combine like terms
2b = -4                              Isolate b by dividing both sides by 2
b = -4/2 = -2

Answer b = -2

Z varies directly as x2. If z = 16 when x = 2, find z when x = 5.<br> ...<br> Z=
PtichkaEL [24]

Answer:

100

Step-by-step explanation:

it is a bit unclear to me, what that problem description means.

if I understand it correctly, than z is directly depending on x².

so, z = 16 for x = 2. x² = 4

I pondered a little bit, as there are several possibilities to connect 16 with 4 as a driving factor (e.g. 2⁴ = 16, 4×4 = 16, 12 + 4 = 16).

I decided to go with the simplest interpretation with the usual meaning of "varies" (multiplication) : 4×x²

that would mean

z = 4×x² = 4×5² = 4×25 = 100
