Answer:
Part 1) Geometric sequence
Part 2) 64 minutes or one hour and four minutes to complete station 5.
Part 3) 512 minutes or 8 hours and 53 minutes to complete station 8.
Step-by-step explanation:
Trust me. I used my calculator.
It's name is “isosceles triangle”
Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get
9x + 5y - 9x + 4y = -33 + 6
9y = -27
y = -3
Substituting this value of y in the first equation, we get
-9x + 4(-3) = 6
-9x - 12 = 6
9x + 12 = -6
9x = -18
x = -2
Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.
