Answer:
No
Step-by-step explanation:
2X + 12=13x - 2x + 5
2X + 12= 11x+5
2x-11x = 5-12
-9x = -7
X = 7/9
so the answer is NO
Answer:
t = 3 s and t = 4 s
Step-by-step explanation:
Given that,
A projectile is fired straight up from ground level with an initial velocity of 112ft/s. Its height as a function of time t is given by :
We need to find the interval of time during which the projectile’s height exceeds 192 feet. It means put h = 192 feet
So,
The above is a quadratic equation, it can be solved using middle term splitting as follow :
Hence, at t = 3 s and t = 4 s, the projectile’s height exceeds 192 feet above the ground.

Answer:
Japan - $21.95
Switzerland - $7.33
Step-by-step explanation:
Let the cost of movies in Japan be x and the cost of movies in Switzerland be y. We can write two equations that relate x to y. If we have two equations and two unknowns we can solve for x and y.
For the total cost of $80.5:
WE can write in terms of y:
and substitute into: total of $76.85:
solve for x
then y is:
