Graph the equation and identify the y- intercept y=1/4 x

5)m<4=13°[being vertically opposite angle)

6)m<2+<3=180°(Being straight angle)

or,m<2=180°-110°

m<2=70°

7)m<1+m<4=180°[being straight angle]

or,m<1=180°-65°

m<1= 115°

Create a real world equality problem, then solve:

Example Problem:

Ana sells at least  220  shirts:

Ana  Sold  85  shirts  in the first  3 weeks  of the month:

How many shirts must Ana sell in the last week of the month?

Solution:

Let   S   =    the number  of  shirts Ana sells in the last week of the month.

Total Number  of Shirts  for the month must be greater than 220:

We Write:     85     +     S      ≥     220

We   Solve the inequality by Subtracting  85  from both sides:   S    ≥    135

Therefore,  Ana must sell  135  or more shirts in the last week to go on the school trip.

Solve:   85     +     s      ≥       220    ========>     S     ≥    135

Let's solve your inequality step-by-step.

85     +     s      ≥       220

Step 1: Simplify both sides of the inequality.

s     +     85      ≥        220

Step 2: Subtract 85 from both sides.

s    +     85      −     85      ≥     220   −   85

s     ≥      135

Answer:

s     ≥     135

Check Problem:

85     +     s      ≥       220    ========>     S     ≥    135

We see that =====>   85     +     135     =    220

If Ana sells 135, or more shirts, The total number of shirts she sells that month will be  220  or more  ========>   Answer  Checked

Hope that helps!!!!!!!!!!!                                     : )
