Answer: 10
p = Pamela’s age, j = Jiris’ age
2j = p
p + j = 30
Then change things around a bit...
p + j = 30 or
30 - p = j
Then substitute
2(30 - p) = p
And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20
Answer:
All systems have 2 real solutions.
Step-by-step explanation:
there are X and Y unknowns.
We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
Answer:
45 m
Step-by-step explanation:
The height at time of launch is at x = 0
Substitute x = 0 into f(x)
f(0) = - 5(0 + 1)(0 - 9) = - 5(1)(- 9) = 45 m
