Answer:
Not geometric
Step-by-step explanation:
In a geometric sequence, each term is multiplied by a common ratio to get the next term.
So if this is a geometric sequence, then dividing each term by the one before it should result in the same common ratio.
42 / 21 = 2
126 / 42 = 3
504 / 126 = 4
The ratios are different. This is not a geometric sequence.
Answer: 12 + 21y
Step-by-step explanation:
Easy peasy
slope=(change in rise)/(change in run)
aka
slope between points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1) since y is rise/up and x is run/leftright
points
(-7,-9) and (-5,-8)
x1=-7
y1=-9
x2=-5
y2=-8
remember minusing a negative means addin a positive
slope=(-8-(-9))/(-5-(-7))=
(-8+9)/(-5+7)=1/2
slope=1/2
positive slopes go from bottom left to top right
since it is less than 1
it is more horizonal than vertical
Answer:
Total different numbers = 400
Step-by-step explanation:
Assume;
Smallest number bigger than 7999( multiple of 5) = 8,000
largest 4 digit number multiple of 5) = 9,995
Computation:
a = 8,000
d = 5
an = 9,995
an = a + (n-1)d
9,995 = 8,000 + (n-1)5
1,995 = (n-1)5
399 = n-1
n = 400
Total different numbers = 400
Step-by-step explanation:
since all angles add up to 180:
(8x-1)+(3x+4)+(3x+9)=180
add like terms:
14x+12=180
x=12
Hope that helps :)
