the answer is a
you can subsitute or work backwards
What do you mean? Question not clear.
Answer:
x=0
Step-by-step explanation:
First make the bases the same.
5^x+4 = 5^4
Now since the bases are the same it also means that the power should also be the same.
So: x+4 = 4
x=0
Answer:
where's the equations and expressions..?
I can give you several pair of values that are possible and explain how to find them, such that you can apply the same to your options and choose the right ones.
The fact that z and w are inversely related means that their product is constant, this is:
v * w = constant.
The statement tells that the value ot the constant is 2/3, then:
v * w = 2/3
Now, you can solve for any of the variables and get:
v = (2/3) / w or w = (2/3) / v
Here are some values that meet that relation:
v w = (2/3) / v
-8/9 (2/3) / (-8/9) = - (2/3) * (9/8) = -3/4
- 4/9 (2/3) / (-4/9) = - (2/3) * (9/4) = - 3/2
- 2/9 (2/3) / (-2/9) = - (2/3) * (9/2) = - 3
2/9 (2/3) / ( 2/9) = (2/3) * (9/2) = 3
4/9 (2/3) / (4/9) = (2/3) * (9/4) = 3/2
