How do you solve the equation 5/x= x-4

x=5

Step-by-step explanation:

write x - 4 as a fraction with denominator = 1

5/x = (x - 4)/1

Now cross multiply

x(x - 4) = 5    multiply out and collect all terms on the left side of the equal sign

x2 - 4x - 5 = 0    factor the quadratic into two binomials

(x - 5)(x + 1) = 0   the product of two numbers = 0 when either number is zero

Therefore x = 5 or x = -1

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

a. she will receive a refund of $278.
