Answer:
24miles/hour
Step-by-step explanation:
8miles/20minutes
1hour-->60minutes
60÷20=3
8×3=24miles
Answer:
The correct option is A.
Step-by-step explanation:
The given equation is

Put x=0, in the given equation.

The y-intercept is (0,32).
Put y=0, to find the x-intercept.





Therefore the y-intercepts are (-4,0) and (8,0).
The vertex of a parabola
is


Put x=2 in the given function.



The vertex is (2,36).
Therefore option A is correct.
Answer:
As per Given Information
→ ∠AOB = 7x-99°
→ ∠COD = 2x + 1°
we have to find the value of x .
∠AOB = ∠COD ( Vertically Opposite Angle)
On putting the value we obtain
➺ 7x-99° = 2x + 1°
➺ 7x -2x = 1° + 99°
➺ 5x = 100°
➺ x = 100°/5
➺ x = 20°
So, the value of x is 20° .
Answer:
B
Step-by-step explanation:
the answer is B because, our range starts at 2 but does not include 2 and continues to infinity (x>8) does not have a boundary.
