Best way to solve would be using Elimination Method. Here's how to solve.
9x + 8y = 15
9x + 8y = 30
To cancel out a variable multiply one equation with -1.
9x + 8y = 15
-1(9x + 8y = 30)
Distribute.
9x + 8y = 15
-9x - 8y = -30
Add both equations together.
0 = -15
So no solution would be your answer. I hope this helps love! :)
P = price of tickets
8.50p = 42.50
you then divide 8.50 on both sides
8.50p = 42.50
——— ———
8.50 8.50
p = 5
meaning Allison bought 5 tickets in total.
Area of a triangle is 1/2 x base x height.
The graphed triangle has height of 2 and base of 2.
Area = /2 x 2 x 2 = 2 square units.
The triangle gets enlarged by a scale factor of 2, so the new height would be 2 x 2 = 4 and the new base would be 2 x 2 = 4
Area of enlarged triangle = 1/2 x 4 x 4 = 8 square units.
The answer is C) 8
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
