Answer:
x = -15
Step-by-step explanation:
In fractional equations we cross multiply the expressions:
In cross multiplying the denominator of the first fraction is multiplied with the numerator of the second fraction and vice versa:
-2x = 30 divide both sides by -2
x = -15
Answer:
43.667 years
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
A = 10,000
P = 5,000
r = 0.016
n = unknown
Step 2: Substitute variables
10,000 = 5,000(1 + 0.016)ⁿ
Step 3: Solve for <em>n</em> time
2 = (1.016)ⁿ
43.667 years
Answer: There can be more than one zero
An x-intercept is located at the point on the function where the value of x is 0.
theres a lot lol. can you be more specific if these are wrong?
Step-by-step explanation:
The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.
According to the statement
We have a given that the maximum sum of the positive integers is 400.
And we have to find the value of n which is a maximum number of integers by which the value of sum become 400.
So, to find the value of the n we use the
A.P. Series'Summation formula
According to this,
S = n (n+1)/2
Here the value of s is 401
Then
S = n (n+1)/2
401 = n (n+1)/2
401*2 = n (n+1)
802 =n (n+1)
n (n+1) = 802
n^2 + n -802 =0
By the use of the Discriminant formula the
value of n becomes n = -28 and n = 27.
The negative value of n is neglected.
Therefore the value of n is 27.
So, The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.
