last year the cost of a season ticket for a rugby club £370. This year the cost of a season ticket for the club has been increas
Elden [556K]

Answer:

\frac{80}{370} OR \frac{8}{37}

Step-by-step explanation:

So first you find the difference between the new cost and the old cost:

450 - 370  = 80

So the increase was 80.

When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).

Thus the answer becomes \frac{80}{370}

But you can always reduce it to its lowest terms thus:

\frac{8}{37}

Using the point-slope formula, what is the equation of the line that passes through the points (1,5) and (0, 0)?
DerKrebs [107]

Answer:

y =5x

Step-by-step explanation:

y_{1}-y_{2}  = m(x_{1} - x_{2} )

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

y_{1}-y_{2}  = m(x_{1} - x_{2} )

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x

Savatey [412]
Jacob has the faster time because if you make the fractions equal you would make the denominators equal by rounding 3/4 to have a denominator of 12 making it 9/12 which is larger then 5/12 making Daniel's time slower then Jacob's.
