Answer:

(B)          

Step-by-step explanation:

Given: A triangle whose coordinates are (0,0), (x_{1},y_{1}) and (x_{2},y_{1}).

To find: The area of the triangle.

Solution: We know that Area of triangle=\frac{1}{2}{\times}base{\times}height.

Now, Base=\sqrt{(x_{2}-x_{1})^{2}+(y_{1}-y_{1})^{2}}

Base=(x_{2}-x_{1})

And height=\sqrt{(0-0)^2+(y_{1}-0)^2}

Height= y_{1}

Therefore, area of triangle= \frac{1}{2}{\times}(x_{2}-x_{1})}{\times}y_{1}

Area of triangle=\frac{1}{2}y_{1}(x_{2}-x_{1})}

 A movie theater sends out a coupon for 85​% off the price of a ticket. Write an equation for the​ situation, where y is the pri
ra1l [238]

Answer:

y=0.15x

Step-by-step explanation:

Given:

Original price of the ticket is x

Price after using the coupon is y

Coupon discount is 85% of x=0.85x

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line y=0.15x strictly remains in the first quadrant as both x and y can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of x and y positive.

Josh sold his bike for 10% less than he paid for it. IF he sold the bike for 585 how much did he pay for it?
tangare [24]

Answer:

To know how much he bought it for, let's consider the actual amount it be x.

Step-by-step explanation:

10% of x + $585 = x

x/10 + $585 = x

$585 = x-x/10

$585= 9x/10

9x=$5850

x=$5850/9

x=$650

.: the actual price was $650.
