Yo yo yo so first u simplify everything as 4^2= 16 and 25 squared is 5 so order of operations make 5*2 and that equals 10 so finally
16-10=6 so the answer is 6
X-intercept = 25.
y-intercept = -20.
To find the x or y intercept you're trying to find the point in which the line crosses that particular axis. In other words, you would want to find what x equals when y is zero and what y equals when x is zero.
- 4(0)-5y=100 : 5y=100, 100/5= 20, y-intercept = -20
- 4x-5(0)=100 : 4x=100, 100/4= 25, x-intercept = 25
- x-intercept is (25,0) ; y-intercept is (0,-20)
(f+g)(x) is basically equal to f(x)+g(x), so you're just adding the two functions together.
