Answer:
Step-by-step explanation:
k is a real number.
We take the square root of both sides of the equation.
Simplifying the equation.
Two of them are 1/4 and 2/8! Hope this helps:)
Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2
See attached picture
Answer:
Given Two equations :-
- multiplying eq.(i) by 2 eq.(ii) by 3.
- <u>placing this value of y² in eq. (i)</u>
3x²- 2×9 = 57
3x² - 18 = 57
3x² = 57 + 18
3x²= 75
x² = 25
<u>x = ± 5</u>
<h3>So, the values of x are <u>+5 and -5</u> </h3><h3>and the values of y are
<u>+3 and -3</u></h3>
