Answer:
The table C
Step-by-step explanation:
when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.
We have an arithmetic progression:
An arithmetic progression is a sequence of numbers such that the diference between the consecutive terms is constant.
Explicit formula:
an=a₁+(n-1)*d
a₁ is the first term
d is de common diference
n is the numbers of terms
In this case:
a₁=-9
d=an-an-1=a₂-a₁=-16-(-9)=-16+9=-7
an=-9+(n-1)*(-7)
an=-9-7n+7
an=-7n+-2
a₁=-7*1-2=-9
a₂=-7*2-2=-14-2=-16
a₃=-7*3-2=-21-2=-23
a₄=-7*4-2=-28-2=-30
a₅=-7*5-2=-35-2=-37
a₆=-7*6-2=-42-2=-44
Answer:
the answer to that is -1i
Step-by-step explanation:
cause if you add negative and positve you get to subtract it and get the sign of the highest number
