1) Make them into equations.
0.05x + 20 = 0
0.07x + 10 = 0
2) Equate the two.
0.05x + 20 = 0.07x + 10
0.02x = 10
x = 500
Answer:
Point-slope equation is
y-y1 = m(x-x1)
m is a slope, m=5/4
y1 = -5, x1 = 8
Point-slope equation is
y+5 = 5/4(x - 8).
Step-by-step explanation:
Answer:
5 feet
Step-by-step explanation:
When you place a 13-food ladder against the top of a 12-foot building, the ladder becomes the hypotenuse of the right angle triangle formed.
Let x be the distance of the bottom of the ladder away from the bottom of the building.
Using the Pythagoras Theorem we obtain:
This implies that:
The bottom of the ladder will be 5 feet away from the bottom of the ladder
