Answer:
Jason -- 36
Shauna -- 12
Step-by-step explanation:
This question in set to the future 4 years so in order to actually solve it, we need to subtract the years to the present. The number of years to subtract is 8 to account for both people's combined age.
so ....
x -- shaunas age
3x + x = 56 -8
4x = 48
x= 12
Therefore Shauna is 12 years old. Because Jason is three times Shauna's age, he is 36
Answer:
The solution set is { (3, 4), (5 , 0) }.
Step-by-step explanation:
x^2 + y^2= 25
2x + y = 10
We use substitution:
From the second equation y = 10 - 2x.
Substituting for y in the first equation:
x^2 + (10 -2x)^2 = 25
x^2 + 100 - 40x + 4x^2 - 25 = 0
5x^2 - 40x + 75 = 0
Divide through by 5:
x^2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
x = 3, 5.
when x = 3 , y = 10 - 2(3) = 4.
when x = 5, y = 10 - 2(5) = 0.

Step-by-step explanation:
•A sinusoidal function is a function in sine or in cosine •The amplitude of a graph is the distance on the y axis between the normal line and the maximum/minimum. It is given by parameter #a# in function #y = asinb(x - c) + d or y = acosb(x - c) + d# •The period of a graph is the distance on the x axis before the function repeats itself. Hope this helps you! :)
24:30 you multiply it both by 2 because 30 minutes plus another 30 minutes is an hr which is the same as 30*2 so 24 times 2 is 48 and 30 times 2 is 60
24:30
48:60
the answer is 48
