The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
a_n = -10 + 8(n-1)
or
a_n = -18+8n
The last term corresponds to
110 = -18+8n
128 = 8n
16 = n
So, the summation can be written as
The answer would be, A) +$2 because he spend $12 but earned $14 so when you subtract 14 and 12 you get $2, which would be his profit
Answer:
y = (2x/9) + 1
Step-by-step explanation:
Solving for y we get 3(-2y+x) = 5(-3y+x)+9
Expand the above we get -6y+3x=5(-3y+x)+9
which is -6y+3x = -15y+5x+9
then 9y = 2x+9
which y = (2x/9) + 1
Answer:
C. (5x√2)² = 50x²
Step-by-step explanation:
Area of parallelogram = QR²
QR = √((5x)² + (5x)²) ---› pythagorean theorem
QR = √(25x² + 25x²) =
QR = √(50x²)
QR = √(25*2*x²)
QR = 5x√2
✔️Area of parallelogram = QR²
= (5x√2)² = 25x² × 2 = 50x²
Answer:
9
Step-by-step explanation:
Just divide the amount moved by the number of spaces. If you spun the same number 10 times, and went back 90 spaces, your number would be 90/10
