Answer:
the x intercept is -4
Step-by-step explanation:
to find the x intercept, set y = 0 and solve for x
y = 5x+20
0 = 5x+20
subtract 20 from each side
-20 = 5x +20 -20
-20 = 5x
divide each side by 5
-20/5 = 5x/5
-4 =x
The answer you selected in that photo given, is correct. I can tell just by using common sense and by judging the other options second option (B) is looking the most clearest one to me.
A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
Okay, here we have this:
Considering the provided function, we are going to calculate the requested one-side limits, so we obtain the following:
