Mandela served as president of South Africa for five years.
Challenges can be overcome through hard work and persistence.
Mandela encouraged peace in his country while he was president.
Answer:
In Nelson Mandela's family he was the first to receive a formal education. At that time, very few black kids attained high school education in South Africa.
The system of equations can be used to determine whether the road intersects the boundary of the tower’s signal; y = 2( x - 4 )² + 2 and 5 x + 11 y = 62.
If a quadratic equation is written in the form
y = a(x-h)^2 + k
then it is called to be in vertex form.
It is called so because when you plot this equation's graph, you will see the vertex point is on (h,k).
To determine a quadratic function in vertex form:
y = a ( x - 4 )² + 2
4 = a ( 5 - 4 )² + 2
4 = a + 2
a = 2
y = 2 ( x - 4 )² + 2
Then we will determine a linear function in standard form, that passes through the points ( -3, 7 ) and ( 8, 2 ).
7 = -3 m + b
2 = 8 m + b / ·(-1)
7 = - 3 m + b
- 2 = - 8 m - b
5 = - 11 m
m = -5/11,
2 = -5/11 · 8 + b,
b= 2 + 40/11,
b = 62/11
Substitue,
y = - 5/11 x + 62/11 / ·11
11 y = - 5 x + 62
5 x + 11 y = 62
Finally the system of equations is:
y = 2( x - 4 )² + 2
5 x + 11 y = 62

The graph is a horizontal shift of the function two units to the left.
The graph of the parent squareroot function is;
The horizontal shift is obtained by determining the change being made to the x-value. The horizontal shift is C.
If the horizontal shift is positive, the shifting moves to the right.
If the horizontal shift is negative, the shifting moves to the left.
The square root parent function is,
There is a shift in positive x-direction 2 units.
When the constant is negative the shift is to the right in c units, and when the constant is positive (like in this case) the shift is to the left in c units.
Hence, the graph is a horizontal shift of the function two units to the left.
