Answer:
x = 4/3
Step-by-step explanation:
f(x) = 3x - 1
f(x) = 3
set equal
3x - 1 = 3
add 1 to both sides
3x = 4
Divide both sides by 3
x = 4/3
Answer:

x>480
b. When the number of calls per month is greater than 480, then Plan 1 is more economical. Example: If the number of calls is greater than 480 say 500, then charges in plan 2 will be $39, but Plan 1 is more economical and charges will be $38.
Answer:
Use the given slope and point to substitute into the point-slope formula y−y1=m(x−x1).
Slope-intercept form:
y=3x²+4x−25
Point-slope form:
y+5=(3x+10)⋅(x−2)
Step-by-step explanation:
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
