Answer: f(3)= 7, f(0)= -5, f(-2)= -13
Step-by-step explanation:
Substitute and plug in.
For f(3), we plug in 3 for x in the equation.
So, 4(3)-5, which is just 12-5, which is 7
We do the same for f(0),
4(0)-5, which is 0-5, which is -5
Once again for f(-2),
4(-2)-5, which is -8-5, which is -13
Hope this helps!
I think as that is a variable so when you like add there is already a constant so it is 1
1+1+1+1= 4
x=1
Answer:
perpendicular lines
Step-by-step explanation:
when the two equation are written in slope intercept form:
y = -4x -7
y = 1/4x -2
the slopes are opposite reciprocals which means they are perpendicular
