Answer:

1/2

Step-by-step explanation:

y = 1/2x - 1/3

This is written in the form y = mx+b where m is the slope and b is the y intercept.

The slope is 1/2 and the y intercept is -1/3

Point B lies between points A and C, and all three points lie on point AC, which of the following is not true? A. Point B lies o
loris [4]

Answer:

C. Point A lies on ray BC

Step-by-step explanation:

Points A and C can be connected by a segment which would be a measure of the distance between the points. Locating point B between AC, makes the three points lying on segment AC.

A ray extends from a point to infinity, a line extend to infinity on both sides, while a segment is known to have two endpoints. Therefore, points AC are the end points of the segment AC, and point B between this segment confirms that point B lies on the segment AC. Therefore, Point A lies on ray BC is not correct.

A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
Feliz [49]

Answer:

11.4 metres

Step-by-step explanation:

Use Pythagoras theorem for a right-angled triangle

a^2 + b^2 = c^2

if you cut the rectangle in half, it will become a right angled triangle.

a and b are two sides of the rectangle, while c is the diagonal or hypothenuse

so 9^2 + 7^2 = c^2

81 + 49  = c^2

c^ 2 = 130

square root 130 = c

you should get approximately 11.4 metres

Help please ! ill give brainliest if correct
Mashutka [201]

9514 1404 393

Answer:

  a) (-5±√10)/3 ≈ {-2.721, -0.613}

  b) (6±√21)/5 ≈ {0.283, 2.117}

Step-by-step explanation:

a) The relevant coefficients are ...

  a = 3, b = 10, c = 5

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-10\pm\sqrt{10^2-4\cdot3\cdot5}}{2\cdot3}=\dfrac{-10\pm\sqrt{40}}{6}\\\\\boxed{x=\dfrac{-5\pm\sqrt{10}}{3}\approx\{-2.721, -0.613\}}

__

b) The relevant coefficients are ...

  a = 5, b = -12, c = 3

  x=\dfrac{-(-12)\pm\sqrt{(-12)^2-4\cdot5\cdot3}}{2\cdot5}=\dfrac{12\pm\sqrt{84}}{10}\\\\\boxed{x=\dfrac{6\pm\sqrt{21}}{5}\approx\{0.283, 2.117\}}
