we have given that 3+(-3) and (10.4)+(-10.4).

we know that a property (a)+(-b)=a-b.

so (3)+(-3) and (10.4)+(-10.4)=0.

these number are called opposites because they have same value but opposite signs.

so the number and opposite of a number is added always equal to 0.

Evaluate 5/6F - 3/4F = 1/4.
Crazy boy [7]
5/6F - 3/4F = 1/4
5x4/24F - 3x6/4F = 1/4
20/24F - 18/24F = 1/4
20F - 18F = 1/4x24
2F = 6
F = 6/2
F = 3

Which of the following is a true statement about the equation y= -7/8x+10
-BARSIC- [3]
First of all we can rule out that the slope is 10. The coefficient before the x term is not 10 so the answer is not a.

Following on what I said for option a, option b is correct as the coefficient before the x term is -7/8. Therefore the answer is B.

The answer is not C as when x = 0, y is not 0. This means the line does not pass through the origin (0,0)

Option D is not true aswell. When x = 1, y= 9.125. When x= 2, y= 8.25. When x=3, y= 7.375. X is increasing whereas y is decreasing. Therefore option D is ruled out.

The answer is option B.

I hope this has helped you.

Please mark as brainliest if you are happy with this explanation. Have a great day!

If a point B(2,5) lies on a circle with center at origin,then what will be the length of the
lianna [129]

Answer:

r = \sqrt{29}

Step-by-step explanation:

The distance from the centre to a point on the circle is the radius r

Calculate r using the distance formula

r = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 5 )

r = \sqrt{(2-0)^2+(5-0)^2}

  = \sqrt{2^2+5^2}

  = \sqrt{4+25}

  = \sqrt{29}
