Answer:
A & D for sure. Probably B
Step-by-step explanation:
Students don't own their homes. Homeowners in your neighborhood might not meet the definition of Random.
Y = -x + 4
y = 3x + 3
3x + 3 = -x + 4
3x + x = 4 - 3
4x = 1
x = 1/4
y = 3x + 3
y = 3(1/4) + 3
y = 3/4 + 3
y = 3/4 + 12/4
y = 15/4
solution is (1/4,15/4)
so line y = -x + 4 intersects the line y = 3x + 3 at (1/4,15/4)
Answer:
Step-by-step explanation:
By comparison,
Taking the LCM and simplifying implies,
1min: 100 ft
2min: 100(.5)= 50 ---> 100+50= 150 ft
3min: 50(.5)=25 ---> 150+25= 175 ft
4min: 25(.5)=12.5 ---> 175+12.5= 187.5 ft
5min: 12.5(.5)=6.25 ---> 187.5+6.25= 193.75ft
answer: 193.75 ft
