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...

∴The perimeter of the trapezoid= 30 feet</h2>
Step-by-step explanation:
Given that the parallel bases of a trapezoid measure 2 feet and 6 feet and the legs measured 9 feet and 13 feet.
∴The perimeter of the trapezoid = sum of all sides
= (2+6+9+13) feet
= 30 feet
Answer:
*In Explanation
Step-by-step explanation:
<u>1) Start by just substituting the value of x (given in equation 1) into the second equation:</u>
y = 3x - 1
y = 3(2) - 1
y = 6-1 = 5
<u>2) Since both equations have x on one side, make both equations equal to one another:</u>
2y + 4 = 9 - 3y
<u>Solve for y:</u>
5y = 5
y = 1
<u>Plug y = 1 into either one of the given equations and solve for x:</u>
I'll use first equation:
x = 2y + 4
x = 2(1) + 4
x = 6
<u>3) When substituting X into the second equation, remember to use parenthesis:</u>
The student was substituting x from equation 1 into equation 2, but they forgot to multiply ALL of 2y + 3 by 2.
x = 2y + 3
Substitute into 2nd eqn:
y = 2(2y + 3) - 9
So its going to equal a fraction.
To convert let x equal the repeating decimal (0.1515... it would usually have a line on top of it but I cant type it)
Then examine the number see what place it is in then add another place (in this case it is in the 10000ths place) so multiply it but 10000x
so it would look like: 10000x = 0.1515
then you will move the decimal in to a whole numbers place (0.1515 to 1515.1515
then subtract the decimal 1515.1515- .1515= 1515.
dont forget to subtract from both sides so subtract the 10000x too. (999.515)
then write as fraction form 1515/9999
