One month = 5000

Number of months before the spark plugs need to change :

15000 ÷ 5000 = 3

The sparks can last 3 months before it needs to be changed.

Number of times it need to change in a year = 12 ÷ 3 = 4

-----------------------------------------------------------------------------
Answer : It needs to be change 4 times a year.

2 x - 17 = 11.<br> Help please
Svet_ta [14]

Step-by-step explanation:

Perhaps you want to solve the equation for the value of x. If so then let us work it out:

2x - 17 = 11 \\ 2x = 11 + 17 \\ 2x = 28 \\ x =  \frac{28}{2}  \\  \huge \red { \boxed{x = 14}}

What is the explicit rule for the sequence?<br><br><br><br> 12,6,0,−6, …
wolverine [178]
Hello!

First you find the common difference in the sequence

6 - 12 = -6
0 - 6 = -6

The common difference is -6

We can now make the equation

-6(n - 1) + 12

we got the 12 because it is the first number in the sequence

Simplify

-6n + 6 + 12

Simplify

18 - 6n

The answer is B) an = 18 - 6n

Hope this helps!

Find the equation of a line parallel to y=2x-4 that contains the points (5,1)
Alex73 [517]
The correct answer is
y=2x-9

Since the lines are parallel, they will gave the same slope (in this case it’s 2)

Our equation will be
y=mx+b

We know the slope is 2, and they’ve given us x and y coordinates. Plugging it in to the slope equation we get

1=2(5)+b

1=10+b

Subtract 10 from both sides and you get

-9=b

Putting it together our new parallel line will be

y = 2x - 9
