Answer:
Principle for account B is greater.
<em></em>
Step-by-step explanation:
First of all, let us have a look at the formula for Simple Interest:
Where 
is the principle amount
is the Rate of interest per annum
is the time in years.
Time = 21 months = 
Let the Principles be 
.
Using the formula for Simple Interest, we get:
Therefore, <em>principle for account B is greater</em>.
Answer:
GCF: (x - 2)
4 / (x + 5)
Step-by-step explanation:
The expression given is:
(4x - 8) / (x² + 3x - 10)
To find the greatest common factor, we have to factorise the numerator and denominator individually.
NUMERATOR:
4x - 8 = 4(x - 2)
DENOMINATOR:
x² + 3x - 10 = x² + 5x - 2x - 10
x² + 3x - 10 = x(x + 5) - 2(x + 5)
x² + 3x - 10 = (x - 2) ( x + 5)
So, the expression becomes:
4(x - 2) / [(x - 2) ( x + 5)]
We observe that the common factor in both numerator ad denominator is (x - 2).
This is the greatest common factor (GCF).
Factoring out (x - 2), the expression can be rewritten as:
4 / (x + 5)
Y = -3(2) + 11
y = -6 + 11
y = 5
Answer is a) y = -3x + 11 , when x is 2 y is 5

<h3><u>Key Concepts for Reflections:</u></h3>
- if (a, b) is reflected on the <em>x-axis</em>, the image is the point <em>(a, -b)</em>
- if (a, b) is reflected on the <em>y-axis</em>, the image is the point <em>(-a, b)</em>
- if (a, b) is reflected on the line<em> y = x</em>, the image is the point <em>(b, a)</em>
- if (a, b) is reflected on the line <em>y = -x</em>, the image is the point <em>(-b, -a)</em>
