Answer:
Geometric sequence
Step-by-step explanation:
Since the accidents increase by 5% this represents that the number is increasing exponentially . So the sequence is geometric sequence. The geometric sequence can be represented by: a, ar, ar^2, ar^3...
Answer:
Step-by-step explanation:
That weird symbol means "element". In our case, the elements of the domain (the x-values) are -15, -6, -1. Which tells us that we are going to sub each one of the numbers into the equation and solve it for the corresponding y value. That in turn gives us the coordinate point. The equation is
x + y = 6
Subbing in first -15 for x:
-15 + y = 6 and
y = 6 + 15 so
y = 21 and the coordinate point is (-15, 21).
Subbing in -6 for x:
-6 + y = 6 and
y = 6 + 6 so
y = 12 and the coordinate point is (-6, 12).
Subbing in -1 for x:
-1 + y = 6 and
y = 6 + 1 so
y = 7 and the coordinate point is (-1, 7)
The second choice is the one you want.
Just remember that x is the domain and any elements in the domain go in for x.
Also remember that y is the range and any elements in the range go in for y

To find out, we solve the system of equations.
n + q = 52
n = -q + 52
Plug in -q + 52 for 'n' in the 2nd equation:
0.05(-q + 52) + 0.25q = 8
Distribute 0.05:
-0.05q + 2.6 + 0.25q = 8
Combine like terms:
0.2q + 2.6 = 8
Subtract 2.6 to both sides:
0.2q = 5.4
Divide 0.2 to both sides:
q = 27
Now plug this into any of the two equations to find 'n':
n + q = 52
n + 27 = 52
Subtract 27 to both sides:
n = 25
So Alexis had 27 quarters and 25 nickels.
14. Was the perimeter calculated correctly?
- Breadth = 1 *2/5 yards = 7/5 yards
We know that,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 4 + 7 / 5 )
= 2 ( 20 + 7 / 5 )
= 2 × 27/5
= 54 / 5
= 1 * 4/5
No ...
