Answer:
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Step-by-step explanation:
A: 40 because supplements add up to 180
B: 54 because complements add up to 90
Top left -4,4
Top right 4,4
Bottom left -2,-2
Bottom right 4,0
X=$30
y=$60
1 hour job- 60x1=60+30=90
3 hour job-60x3=180+30=210
The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
