For this case we have the following system of equations:
We multiply the first equation by -4:
We have the following equivalent system of equations:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:

Find the solution set of x: x^2-7x= - 10.
Answer:
(x − 2)(x −5)
Step-by-step explanation:
x² - 7x = - 10
x² - 7x + 10 = 0
Find two numbers that when added together make −7 , and when multiplied make - 10.
The numbers − 2 and −5 fit the criteria.
x2− 7x + 10 = (x − 2)(x −5)
Answer:
15.6
Step-by-step explanation:
Answer:
f(3) = -16
Step-by-step explanation:
f(1) = -16
f(n) = f(n-1)
f(2) = f(2-1) = f(1) = -16
f(3) = f(3-1) = f(2) = -16
