Graphs of y = x+- 1 and of y = x - 1 are shown in the figure below.
The intersection of the two graphs is the solution for the two equations.
Answer:
There is no solution.
Explanation:
It is clear that the two lines are parallel and will never intersect.
Note that the equation for a straight line is of the form
y = mx + b
where
m = slope,
b = y-intercept.
y = x + 1 has slope of m=1.
y = x - 1 has slope of m=1.
The two slopes are equal.
Because parallel lines do not intercept, there is no solution.
> y(1) = -5x + 3
-3. -3
> -2 = -5x
÷-5. ÷-5
= 0.4 = x
Answer:
15?
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
f (x)= -5x+1.
Let x = -3
f(-3) = -5(-3) +1
=15 +1
= 16
