Answer:
Step-by-step explanation:
f(3)=-5(x+5)
=5(3) +5
=15+5
f(3) =20
Answer:
Step-by-step explanation:
1+12=30
√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1

Answer:
The first four terms of the sequence are: {-10,-23,-62,-179}
Step-by-step explanation:
Given recursive formula is:

First term = a1 = -10
The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.
Putting n=2

Putting n=3

Putting n=4

Hence,
The first four terms of the sequence are: {-10,-23,-62,-179}
