Answer:
t is common practise to label the vertices of a triangle with capital letters
Answer:
32 square units
Step-by-step explanation:
Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
Just set up 2 equations.
267 = 10(11) + 5(x) + 1(y)
x = y - 7
you can plug the second into the first and get
267 = 110 + 5(y - 7) + y
157 = 5y - 35 + y
6y = 192
y = 32
x = 32 - 7 = 25
thus, 32 $1's and 25 $5's
