To identify the x-intercept, we must put the equation is Standard Form.

Standard Form: Ax+By=C

Algebraic Solving:

-1/2x+y=1/2x-1/2x+3

•We must subtract 1/2x from both sides to cancel it out from the right and move it to the left.
——————————————————

-1/2x+y=3

•The equation is now in standard form: Ax+By=C.
——————————————————

To identify the x-intercept, we will substitute zero in for y because we want to find where the line crosses or intercepts the x-axis, not the y-axis.

Set y=0

-1/2x+y=3

-1/2x+(0)=3
—————————

-1/2x=3

-1/2x•-2/1=3•-2/1

• To cancel out a fraction, we use the reciprocal, meaning the fraction is just flipped. This cancels out fraction and leaves us with x.
———————————————————————

x=6/1

x=6.

Therefore, the line crosses the x-axis at (6, 0)

It is the third option - 48.5%

Get the total of the even number then divide it by the total number of results.
For even, there are 67 twos, 59 fours, 71 sixes. The total is 406.
   
   P(even) = [even] / [total]
   P(even) = [67+59+71] / [67+59+71+64+73+72]
   P(even) = 48.5% 

The experimental probability of rolling an even number is 48.5%.

A soccer player stands in the southeast corner of a 76-meter by 57-meter field and kicks a
sukhopar [10]

Answer:

228m

Step-by-step explanation:

Let's draw a rectangle ABCD, A being its bottom left point, B bottom right, C top right and D top left.

That is our soccer field. The player stands in the southeast corner, which is top right corner or, in our case point B. He passes the ball to the player in the opposite corner, which is corner D. He then passes the ball to the player in the southwest corner, which is corner A. And he finally passes it back to the player in the corner B.

So, the ball goes from B to D to A to B. That means that the ball went along the circumference of the triangle DAB.

So, to answer how long the ball travelled we need to find the circumference of the triangle. The circumference is the sum of its three sides. One side is the field's length (76m) and the othet is field's width (57m). We only need to find the triangle's hypotenuse, side BD, using Pythagoras theorem:

BD² = AB² + AD²

BD² = 76² + 57²

BD = 95

So, the circumference of the triangle is 76+57+95=228m
