Parallel lines have equal gradients;
Gradient of line 2 is thus 0
y=c
Replacing value of y=6 gives
c=6
Equation of the line is thus y=6
The solution of the equation 4x² - 20x + 9 = 0 will be 0.5 and 4.5.
<h3>What is a quadratic equation?</h3>
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
The equation is given below.
x² - 5x = -9/4
Then the equation can be written as
4x² - 20x + 9 = 0
Then the factor of the equation will be
4x² - 20x + 9 = 0
4x² - 18x - 2x + 9 = 0
2x(2x - 9) -1 (2x - 9) = 0
(2x - 1)(2x - 9) = 0
Then the solution of the equation 4x² - 20x + 9 = 0 will be
x = 0.5, 4.5

Answer:r = 2.81 centimeters
Step-by-step explanation:
The area of this circle can be found using the formula
A=πr^2
Where r = radius of the circle
π is a constant whose value is 3.14
We are given the area of the circle to be 25 square centimeters. To determine the length of the radius of the circle , we will make r the subject of the formula
r^2 = A/π
Taking square root of both sides of the equation,
r = √A/π
Since A = 25 and π = 3.14,
r= √25/3.14
r = 2.82166323992
Approximating to the nearest tenth of a centimeter,
r = 2.81 centimeters
