Step-by-step explanation:
since the two lines are parallel to each other the slopes are equal
y =4x -8
m = 4(y = mx +c)
using the formula
y -y1 = m(x- x1)
y -10 = 4(x -(-2))
y -10 = 4(x +2)
y-10 =4x +8
y = 4x +8+10
y =4x +18(equation of the line)
U should know the area of rectangle is w*l
if we increase it by double or times 2 its area will be
A=2w*2wl
A=4wl
area would be 4 times of original one
Now u can get the answer
<span>When price falls quantity demanded will rise, but for simplicity economists take the absolute value of the elasticity number.</span>
The solution to x^2 - 4x = 5 is x = -1 or 5
<h3>How to solve the equation?</h3>
The equation is given as:
x^2 - 4x = 5
Take the coefficient of x
k = -4
Divide by 2
k/2 = -2
Square both sides
(k/2)^2 = 4
Add this value to the sides of the equation
x^2 - 4x + 4= 5 + 4
Express as a difference of two squares
(x - 2)^2 = 9
Take the square root of both sides
x - 2 = ±3
Add 2 to both sides
x = 2 ± 3
Evaluate
x = -1 or 5
Hence, the solution to x^2 - 4x = 5 is x = -1 or 5
