A student performed the following steps to find the solution to the equation 2 -147+15= 0. Where did the student go wrong?
Step 1. Factor the polynomial into (x+ 5) and (x+9)
Step 2 x=550 012-9=0
Step 3. x= -5 or x=9
OA in Step 1
B. in Step 2
C. The student did not make any mistakes, the solution is correct
D. in Step 3

3; 9 is 8 to -4

step-by-step explanation:

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
