Given the following equation, find the x value if f(x) = -4. f(x) = 5×+11

x = -3

Step-by-step explanation:

f(x) = -4 which you plug in for f(x) = 5x+11

this gets you -4 = 5x+11

subtract 11 from both sides

-15 = 5x

divide 5 on both sides

-3 = x

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
