Determine k if the expression is a perfect square
A quadratic is of the form;
Where (by comparison):
If the above is a perfect square, then
Substitute values for a, b and c
<em>Hence, k = 4</em>
Answer:
A dollar
Step-by-step explanation:
7+3 is 10
3 divided by 1 is 3
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Given the equations:
x = 4y
x - 4y = 0 (1)
Also:
x - y + 3z = 3 (2)
And:
2x - 3y - z = -7 (3)
The solution to the equation is:
x = -4, y = -1 and z = 2
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
