Step-by-step explanation:
Sequence 1:
term1=26
term2=26-3=23
term3=23-3=20
term4=20-3=17
term5=17-3=14
sequence2:
term1=-3
term2=-3+10=7
term3=7+10=17
term4=17+10=27
term5=27+10=37
Answer:
The equation of the axis of symmetry is x = 3
Step-by-step explanation:
Perform the indicated mult., obtaining:
y = 3(x² - 6x + 9) + 4.
Mult. each term inside parentheses by 3, we get:
y = 3x² - 18x + 27 + 4, or
y + 3x² - 18x + 31
Here the coefficients are a = 3, b = -18 and c = 31.
The axis of symmetry is x = -b / (2a), which here is:
-(-18)
x = ----------- = 18/6 = 3
2(3)
The equation of the axis of symmetry is x = 3
Answer:
16
Step-by-step explanation:
I believe the answer is Graph B. Because, graph B is all over the place making it weak , while graph A is in a row making it a strong correlation.
