Suppose that f(x)= 3x +5 and g(x) = -2x+15.
a). Solve f(x)=0
b)Solve f(x) < 0
c) Solve f (x)= g(x)
d) Solve f(x) greater than or equal to g(x)
e)Graph y=f(x) and y= g (x) and label the point thatrespresents the solution to the equeation f(x)=g(x).

a.) 3x+5=0
3x = -5
x = -5/3
b.)3x + 5 < 0
3x < -5
x < -5/3
c.) 3x + 5 = -2x + 15
3x = -2x +10
5x = 10
x = 2
d.) 3x + 5 $\ge$ -2x + 15
5x $\ge$ 10
x $\ge$ 2
e.) find slope of each equation and the y-intercept then graph eachequation then find where the graphs intersect. It will be atpoint (2, 11) as found in letter C.
