Answer:
x=4
Step-by-step explanation:
multiply both sides by 5: 2x-8= -5x+20
move the -5x over: 7x-8= 20
move the -8 over: 7x= 28
divide both sides by seven: x= 4
Answer:
a and d
Step-by-step explanation:
Answer:
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
Answer:
see explanation
Step-by-step explanation:
the result 0 = 0
means the equation has an infinite number of solutions
