You are going to model the population size of a species of bird that is gradually becoming extinct. Which graph is the BEST choi
kvasek [131]
Hey Jay,
Since we can't see the graphs, we can't be entirely sure, but given that we are trying to model the population size of a species of bird that is slowly going extinct. I would say the best graph would be a line graph. Line graphs show changes over time so this would be the best graph to use. Hope this helped!

Cheers,
Izzy

What's the solution of the equation 4[x+2(3x-7)]=22x-65
padilas [110]

Answer:

x = -3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x+2(3x−7))=22x−65

Step 1: Simplify both sides of the equation.

4(x+2(3x−7))=22x−65

(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)

4x+24x+−56=22x+−65

(4x+24x)+(−56)=22x−65(Combine Like Terms)

28x+−56=22x−65

28x−56=22x−65

Step 2: Subtract 22x from both sides.

28x−56−22x=22x−65−22x

6x−56=−65

Step 3: Add 56 to both sides.

6x−56+56=−65+56

6x=−9

Step 4: Divide both sides by 6.

6x = -9

6       6

x =  -3/2
