It's not actually 20 pts it's 10 pts if you send a question and you want 20 pts off it would be 10 for other ppl. like
10pts off = 5
20pts off = 10
30pts off = 15
and so on so it's like counting by 5's each time you lose points
Answer:
The answer should be y=2.5
Answer:
This ordered pair is NOT a solution of the equation.
Step-by-step explanation:
First, it is important to note that ordered pairs consist of (x, y) so in this case
x = 15 and y = -3. And that any variable directly next to a number calls for multiplication. So, plugging in the variables the equation would look like
"-3 = 5 x 15"
To see if 5 x 15 = -3 we will multiply them. 5 x 15 actually equals 75 not -3. So we know this ordered pair is NOT the solution for the problem.
Answer:
uhh
Step-by-step explanation:
Answer:
an = 7.5 - 5.5(n - 1).
Step-by-step explanation:
The common difference d = -5.5.
The first term is given as 7.5.
Explicit formula is
an = a1 + (n - 1)d
= 7.5 + (n - 1)-5.5
= 7.5 - 5.5(n - 1)
