Because of the -2 at the end of the function, we know it is shifted down. The +1 means it is shifted left. The answer is the last graph (the one with a y-intercept of -1).
The situation above is an arithmetic sequence with the third term (a3) equal to $285 and sixth term (a6) equal to $510. To determine the nth term of the arithmetic sequence, use the equation,
an = a1 + (n - 1)d
where a1 is the first term and d is the common difference. To solve for these, use the given values,
285 = a1 + (3-1)(d)
510 = a1 + (5 -1)(d)
Solving for the unknowns gives an answer of a1 = 60 and d = 112.5.Thus, the equation is,
y = 60 + 112.5x
Answer:
-7×-2= 14
7×2=14
-7×2=-14
7×-2=-14
u do the normal multiplication and just add the negative sign
Answer:
285ab-159b
Step-by-step explanation:
distribute 13 and 23 into the parenthesis
78ab-117b+207ab+276b
combine like-terms
78ab+207ab-117b+276b
285ab-159b
