Answer:
-10, -6
6, 10
Step-by-step explanation:
Let the one number be x.
One number is 3/5 of the other number.
The numbers are x and 3x/5.
Add 4 to one number, the sum equals the other number.
There are two possibilities.
A) x + 4 = 3x/5
B) 3x/5 + 4 = x
Solve A)
5x + 20 = 3x
2x = -20
x = -10
Solve B)
3x + 20 = 5x
2x = 20
x = 10
According to A)
x = -10
3x/5 = -6
According to B)
x = 10
3x/5 = 6
Answer:
-10, -6
6, 10
Answer:
The second one is your answer
You have to organize the parameters of the real-world situation that is known and unknown. Also, you have to distinguish which of them are dependent and independent. Next, you assign letters as your variables. Lastly, you make an algebraic expression by translating the relationship into the mathematics.
The amount that it rises each minute forms a geometric sequence...
a(n)=ar^(n-1), and we know that a=100 ft and r=1/2 so
a(n)=100(1/2)^(n-1)
And the sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r)
s(n)=100(1-0.5^n)/(1-0.5)
s(n)=200(1-0.5^n)
So we can call these sums the height function
h(t)=200(1-0.5^t)
So after 5 minutes...
h(5)=200(1-0.5^5)
h(5)=193.75 ft
Answer:
It just had relocation 4 in direction of positive and in term of x so
find f(x-5)
