Answer:
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount
Substitute for A in
Substitute for F in
The total amount is calculated by adding the earnings of Alice, her friend and you
<em>Hence, the total earnings is 5d - 2</em>
Answer:
t = sqrt(595/1289) or t = -sqrt(595/1289)
Step-by-step explanation:
Solve for t:
29/35 = 17/t^2 - 36
29/35 = 17/t^2 - 36 is equivalent to 17/t^2 - 36 = 29/35:
17/t^2 - 36 = 29/35
Bring 17/t^2 - 36 together using the common denominator t^2:
(17 - 36 t^2)/t^2 = 29/35
Cross multiply:
35 (17 - 36 t^2) = 29 t^2
Expand out terms of the left hand side:
595 - 1260 t^2 = 29 t^2
Subtract 29 t^2 + 595 from both sides:
-1289 t^2 = -595
Divide both sides by -1289:
t^2 = 595/1289
Take the square root of both sides:
Answer: t = sqrt(595/1289) or t = -sqrt(595/1289)
Answer:
Kevin
Step-by-step explanation:
If the first three months are free, then it means 12-3=9 (you only pay for 9 months).
That means we must multiply 59 by 9 months, not 12.
59*9=$531.
The answer is $531.
Answer:
f(x) = 0 on x= -1 and x = -2
Step-by-step explanation:
Given function is:
In order to find the value of x on which the function will have value zero we have to factorize the function and find zeroes of the function. The method used will be factorization of polynomial as the function is in polynomial form.
So,
To find the zeroes, putting the function = 0
Hence,
f(x) = 0 on x= -1 and x = -2
