X = (12/5,0)
y = (0,-4)
substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)

Answer:
9/2 or 4.5
Step-by-step explanation:
15/4x6/5 = 3/2x3 = 9/2
y = x³ + 3x² - x - 3
0 = x³ + 3x² - x - 3
0 = x²(x) + x²(3) - 1(x) - 1(3)
0 = x²(x + 3) - 1(x + 3)
0 = (x² - 1)(x + 3)
0 = (x² + x - x - 1)(x + 3)
0 = (x(x) + x(1) - 1(x) - 1(1))(x + 3)
0 = (x(x + 1) - 1(x + 1))(x + 3)
0 = (x - 1)(x + 1)(x + 3)
0 = x - 1 or 0 = x + 1 or 0 = x + 3
+ 1 + 1 - 1 - 1 - 3 - 3
1 = x or -1 = x or -3 = x
Solution Set: {-3, -1, 1}
Answer:
approximately 72.35 minutes
Step-by-step explanation:
there are 1609.344 meters in a mile
john ran 100 meter - which would be 16.09 per mile
9.88 seconds x 16.9 = 166.97 seconds per mile
166.97 seconds x 26 miles = 4341.22 seconds
4341.22 seconds / 60 = 72.35 minutes
