Answer:
im scared for my future, I dont wanna learn about this, it looks hard
Step-by-step explanation:
A. 15-35=-20
b. -2+7=5
c. -10+14=4
d. 60-100=-40
An = A1 + (N-1)d
A1 is the first term (in this case 2)
d is the common difference (what is the difference between all consecutive even numbers? 2)
N is the number of terms to find (in this case 29)
An = 2 + (29-1)2 = 58
I would say none of the above, unless you typed it wrong. The sum is the product of the number of terms minus one and two, plus two more. So it's almost answer B but not really. Good luck with this one.
Answer:
Step-by-step explanation:
Find attached the first sum.
x denotes horizontal and y denotes vertical
When the value of x is positive, it moves to right side and when x is negative, it moves left sides 'x unit'
When the value of y is positive, it moves to up side and when y is negative, it moves down sides 'y unit'
5 cars are 0-9
15 cars are 10-19
55 cars are 2-29
5 + 15 + 55 = 75 total cars are less than 30 miles per gallon.
