Remember that the symbols: ≤ and ≥ are graphed as a solid line. While the symbols: < and > are graphed as a dotted line.
Also, before graphing, it would be better to convert both equations to slope-intercept form.
y ≤ x + 1 is already in slope-intercept form.
y + x ≤ -1 is not written in slope-intercept form. (Slope-intercept form: y = mx + b)
y + x ≤ - 1 (subtract x from both sides)
y ≤ -x - 1
Graphing those lines, you get the graph below. You can see that Part C best represents the solution set systems of inequalities, because that is where both of the shaded lines intersect.
i think is g(1)=-1.
hope that i can
she will sew have sewn five dresses and be 1/3 done with the sixth one in an hour.
3/4 of an hour=45 mins
lucy makes 1 dress per 11.25 minutes
45 mins+11.25 mins=56.25 mins
60 mins- 56.25 mins=3.75 mins
3.75 mins is 1/3 of of 11.25 mins
therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
contact me if you have any questions you are welcome.
