Yint is where the line crosses the y axis or where x=0
set x=0
3y+4x=15
x=0
3y+4(0)=15
3y+0=15
3y=15
divide by 3
y=5
yint is (0,5) or at y=5
Answer:
0.975
Step-by-step explanation:
0.25 in : 12 ft
12 ft → 0.25 in
1 ft → 0.25/12
15 ft → 0.25/12 x 15 = 0.31 inches (nearest inch)
Answer: 0.31 inch
Using the law of Cosine:
Cos(angle) = Adjacent Leg / Hypotenuse
Cos(65) = x / 81.9
x = 81.9 x cos(65)
x = 34.61
The answer is A.
62.85 times so basically 63 times
