Answer:
-20 + 7(n-1)
Step-by-step explanation:
It's already given that d, or the common difference, is 7. The only thing left to do is to find the first term of this sequence.
We are given that
= 50.
If we subtract the common difference 10 times we can find the first term.
- 7 x 10 = -70
50 - 70 = -20
The first term is -20. The only choice that shows this is the first one.
Answer:
First one
Step-by-step explanation:
a11 = a1 + (11-1)(7)
50 = a1 + 70
a1 = -20
an = -20 + 7(n-1)

(a+b)^3 = (-1)^3
The answer is
-8/5 or -1 3/5
reason:
-8 and -5
can’t be divided so instead it becomes a fraction

We have 200 calculators and x are scientific. That means (200-x) are financial.
Total cost = 89x + 599(200-x)
Answer:
this is pretty easy we just replace the x with -1 so
(-1)^2+(-1)9+10
-1*-1=1
-1*9=-9
1+-9=-8
-8+10=2
f(-1)=2
Hope This Helps!!!
