Answer:
No.
Step-by-step explanation:
Use a vertical line test.
Vertical line test: If you can draw a vertical line and it <u>does not</u> cross two points in the line, then it is a function.
So, we draw a line.
Draw it through 9,0
It intercepts two points so No. This is not a function.
Hope this helps plz hit the crown :D

Answer:
The answer to your question is a) C + J + S = 80
b) C = J + 5
c) S = 45 hours
Step-by-step explanation:
a) To represent the number of hours that they work together, just add the variables and equal them to 80.
Carlito + Juan + Sara = 80
C + J + S = 80 Equation l
b) Juan worked 5 hours more than Carlito
Juan = Carlito + 5
J = C + 5 Equation ll
c) Hours worked by Sara
S = 3J Equation lll
C = J - 5
Substitute equation ll and lll in equation l to find J
J - 5 + J + 3J = 80
5J = 80 - 5
5J = 75
J = 75/5
J = 15
-Find S
S = 3(15)
S = 45 hours
Answer:
Step-by-step explanation:
The sum of the first 10 terms of an arithmetic sequence is:
the sum of the second 10 terms is: a₁₁ + a₁₂+...+ a₂₀
And the sum of the first 20 terms of an arithmetic sequence is:
so the sum of the second 10 terms is:
Therefore we have:
and:
