The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.
To find the x-intercept, set y = 0:
-5x + 1/5(0) = 15
-5x + 0 = 15
-5x = 15
Divide both sides by -5:
x = -3.
Therefore, the x-intercept is (-3, 0).

Explanation: For this problem you can substitute f(x) and x for 21 and -6 respectively.
Thus, we have 21=-3(-6)+4
Answer:
14r+11
Step-by-step explanation:
3+5r+9r+8
=11+14r
Your answer is 0, use PEMDAS and left to right 1+1=2 then subtract your 2, so 2-2=0
