Hi!
30 = x
f(x) = -1/5x - 14 find x when f (x) = -8
Set the equation equal to -8
-8 = -1/5x - 14
Add 14 to both sides.
6 = -1/5x
Multiply both sides by -5.
30 = x
Hope this helps! :D
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Answer:
The answer in image one is f(x)=2x Left
The answer in image two is f(x)=x Center
the answer in image three where right Right
Answer:
I. Amount = 5618 Rupees
II. Compound interest = 618 Rupees
Step-by-step explanation:
- Given the following data;
- Principal = 5000 Rupees
- Time = 2 years
- Interest rate = 6%
To find the compound interest;
Mathematically, compound interest is calculated using the formula;
A = P(1 + r)^t
Where;
- A is the future value.
- P is the principal or starting amount.
- r is annual interest rate.
- t is the number of years for the compound interest.
Substituting into the formula, we have;
A = 5000(1 + 0.06)^2
A = 5000(1.06)^2
A = 5000 * 1.1236
<em>A = 5618 Rupees</em>
Next, we would determine the compound interest using the formula;
C.I = A - P
C.I = 5618 - 5000
<em>Compound interest (C.I) = 618 Rupees</em>
I think it is 1,1,O but I don’t think you should believe me because I don’t know this very well
