This is my guess by looking at it. I just started doing this too.
Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74

Uh....idk if its correct or not....math isnt my best subject but gl on ur test ^w^
Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
Answer:
Step-by-step explanation:
What is the cube root of ? This is the question.
We can write:
We will use the below property to simplify:
So, we have:
We will now use below property to further simplify:
Thus, we have:
We know power to the power rule:
Now, we have:
This is the correct answer:
