Answer:

Step-by-step explanation:

Try dividing the first equation by 3. The result will be identical to the second equation. Thus, we have two lines that coincide, and therefore there are an infinite number of solutions.

Sami lights up a candle every 10 minutes. Every candle burns for exactly 40 minutes. How many candles are burning exactly 55 min

xxTIMURxx [149]

Answer:

Step-by-step explanation:

Candle is lit every 10 minutes :

Number of candles lit in 55 minutes:

Starting from 0 minute ; Numbe rod candles lit on 55 minutes = 6

1st candle burns out after 40 minutes

Second burns out after 50 minutes

Third will burn out after 60 minutes

Hence Number of candles still burning :

Number of candles lit - Number of candle burnt out

6 - 2 = 4 candles

Find the equation of a line parallel to y-5=6x-10 that passes through (4,10)

$\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond$

❖ If lines are parallel to each other, they have the same slope.

So the slope of the line parallel to y-5=6x-10 is 6.

Now, since we're also given the point crossed by the line, we write the equation in point-slope form:-

$\sf{y-y_1=m(x-x_1)}$

Substitute 10 for y₁, 6 for m and 4 for x₁:-

$\sf{y-10=6(x-4)}$

On simplification,

$\sf{y-10=6x-24}$

Adding 10 to both sides results in:-

$\sf{y=6x-14}$

So we conclude that Option A is correct.
