Answer:
speed is given by:
speed=distance/time
given that:
1 mile=1,760 yards
1 hour=60 min
then the speed in yards/sec will be:
distance Ashley covered is 15 miles
time=2 hours
thus;
speed=(15x1760)/(2x60)
=220 yards/ min

Hi hope helps you :)
The Answer is
X=10
Explanation:
Answer:
Step-by-step explanation:
The easiest way to understand the answer is to consider two straight lines.
y = 3x + 6
and 2y = 6x + 12
When you graph these two lines, one will be on top of the other. That will give you an infinite number of solutions.
The answer does not depend on the two equations being straight lines. All that is required is that one graph sits on the other. So you could have a pair of quadratics
y = x^2 + 3x + 10
2y = 2x^2 + 6x + 20
would also give you an infinite number of solutions.
Answer:
Step-by-step explanation:
we need to find the equation of the parabola with vertex (-5,3), with axis parallel to the x-axis.
general equation of horizontal parabola is
where (h,k) is the vertex
(-5,3) is the vertex. h=-5 and k=3. plug in the values in the general equation
Now find out the value of 'a' using x intercept (4,0)
Add 5 on both sides
a=1
the equation becomes
