Write a linear equation in standard form given the line passes through (-4,-3) and (6,-2).

1 answer:

7 0

(-2+3)/(6+4)= 1/10

y+3=1/10(x + 4)

y + 3 = (1/10)x + 4/10

y + 30/10 = ( 1/10)x + 4/10

y = (1/10)x + 4/10 - 30/10

y = (1/10)x - 26/10

y = (1/10)x - 13/5

10(y = (1/10)x - 13/5)

10y = x - 26

-x + 10y = -26

Jeanette purchase a concert ticket on a website the original price of the ticket was $75 she used a coupon code to receive 20% d

Radda [10]

Answer:

10%

Step-by-step explanation:

20%=20/100=0.20

75$x.0.20=15$

The price when she received a 20% discount was:

75$-15$=60$

Then, the web site applied a 10% service fee to the discounted price, so you have:

10/100=0.10

75$x0.10=7.5$

60$+7.5$=67.5$

So, if 75$ is the 100% of the price, what percentage represents 67.5$?

75$--------100%

67.5$------x

x=67.5 x 100/75

x=90%

Then,

100%-90%=10%
