Answer:
16 feet
Step-by-step explanation:
The shadow is 20/30 = 2/3 the length of the object, so the 6-foot person's shadow will be 4 ft long. It will begin to emerge when the person is 4 feet from the tip of the building's shadow. That distance is ...
20 ft - 4 ft = 16 ft
from the building.
Answer:
8. x=-5 and y=7
9. x=-2 and y=0
10. x=-6 and y=-10
11. x=8 and y=-4
12. x=9 and y=-9
13.x=4 and y=10
14. x=5 and y=-7
Step-by-step explanation:
2y=-8
We need to clear "y" with inverse operations.
y= -8/2 if 2 was multiplying now is dividing
y= -4
Answer:
x- intercept = 6
Step-by-step explanation:
to find the x- intercept, let y = 0 in the equation and solve for x
2x - 3y = 12
2x - 3(0) = 12
2x - 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6 ← is the x- intercept
