I believe if b were to equal the value of 0, there would be 2 solutions to the function. Or not mainly if the resulting expression turns out to be a difference of squares.
Eg. f(x) = 2x^2 + 0x + 2
2x^2 + 2
2(x^2 + 1)
Here there would not be x intercepts, mainly because x cannot be solved.
Answer:
See below
Step-by-step explanation:
100 ft in 4 min = 25 ft/min
125 feet in 5 min = 25 ft min
so the height is d = 25 * m d = height m = minutes
25* 8 = 200 feet
Answer: x=5/3
Step-by-step explanation:
For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.
5x+5=2x+10
The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".
5x+5=2x+10 [subtract both sides by 2x]
3x+5=10 [subtract both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we have found the unknown number, x=5/3.
