polynomial arithmetic and structure: mastery

factor the following expression
1055 + 533 - 1432 - 7
a (53* + 7)(2-1)
b. (55+ 7)(2x2 - 1)
c (553 – 7)(2x3 + 1)
d. (50* - 7)(35 + 1)

i got 86 for this

hope this !

if you need an explanation just ask

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

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
