Answer: 7.5
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7.5%/100 = 0.075 per year,
then, solving our equation
I = 1200 × 0.075 × 2 = 180
I = $ 180.00
Answer:
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
Case Q: i = p(0.01)(2) = 0.02p
Case R: i = p(0.015)(2) = 0.03p
In case R, the interest earned is 0.03p, which is 1.5 times the interest earned in case Q.
Answer:
Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)
Step-by-step explanation:
When you factorise the equation it would look something like this:
(x + a)(x + b) = 0
This also means:
x + a = 0 and x + b = 0
x = -a and x = -b
Example:
Find where the function y = 2x² + 8x + 6 cuts the x-axis
Factorise the 2 out (highest common factor)
x² + 4x + 3 = 0
(x + 1)(x + 3) = 0
x = -1 or -3
Answer:
A. 15
B. 25.6
C. 41.6
Step-by-step explanation:
You need to divide
Answer:
x = - 10
Step-by-step explanation:
Given
- x = 8 ( multiply both sides by 5 to clear the fraction )
- 4x = 40 ( divide both sides by - 4 )
x = - 10
