Basile [38]4 years ago

The equation seems to be

   1
-------- = 5 ^ (x + 4)
  25

In that case, this is the solution, stept by step:

1) factor 25: 25 = 5^2

          1
=> ----------- = 5^(x + 4)
         5^2

2) invert 5^2

=> 5^(-2) = 5^(x+4)

3) Given that the bases are equal, the exponents also have to be equal:

=> - 2 = x + 4

3) transpose +4:

=> - 2 - 4 = x

=> x = - 6

Answer: - 6

Liam has 9/10 gallon of paint for painting the bird houses he sells at the craft fair each birdhouse requires 1/20 gallon of pai
Rina8888 [55]
So to get the fractions easier to understand you need to put them on the same level you are on. So change the 9/10 gallons to 18/20 ( this makes them easier to deal with the 1/20)
so put 1/20 into 18/20. Liam can paint 18 bird houses.

Why is it important to solve an equation for a specific variable?
Svetllana [295]
It all depends on the importance of the variable its self. Its important to solve it so you know what the variable is and its important to solve one at a time because its impossible to solve a variable completely if you have two of them

Use the graph below for this question:
ehidna [41]

Answer:

The average rate of change from x= -2 to x=0 is 0 (second option)

Step-by-step explanation:

Point A=(-2, 1)=(a, f(a))→a=-2, f(a)=1

Point B=(0, 1)=(b, f(b))→b=0, f(b)=1

Average rate of change from x=a to x=b:

r=(f(b)-f(a)) / (b-a)

Replacing the given values:

r=(1-1) / (0-(-2))

r=(0) / (0+2)

r=(0) / (2)

r=0
