The slope of a line is . -1/3. and the y-intercept is 10/3
Alex_Xolod [135]

Answer:

B

Step-by-step explanation:

If you convert equation B into standard form then:

x + 3y + 10 = 0

x + 10 = -3y

(-1/3)x - 10/3 = y

now this would actually mean that the y-intercept is -10/3 but its the closest answer out of the 3 to the specified requirements for the function.

Answers please! I’m finding the volume and i don’t really get it
MrRa [10]

Answer:

V = 13/2

Step-by-step explanation:

When finding volume you must know the formula on doing so.

<em>Volume = length × width × height</em>

length = 2\frac{1}{2} --> \frac{5}{2}

width = 2\frac{1}{2} --> \frac{5}{2}

height = 3\frac{1}{4} --> \frac{13}{4}

                        <u>mixed number --> fraction</u>

V = \frac{5}{2} x \frac{5}{2} x \frac{13}{4}

V = \frac{25}{4} x \frac{13}{4}

V = \frac{325}{8} or \frac{13}{2}

To determine the distance between two points, we use the equation,
                                   distance = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values for the abscissa and ordinates of the points,
                                distance = √(0 - 2)² + (0 - 5)² = √29 ≈ 5.39 
Therefore, the distance between these two points is approximately equal to 5.39.
