Reduced form of 2ab^2-a^2 b^2/5
Ket [755]

Answer:

2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}

Step-by-step explanation:

Given the expression

2ab^2-\frac{a^2b^2}{5}

\mathrm{Convert\:element\:to\:fraction}:\quad \:2ab^2=\frac{2ab^25}{5}

2ab^2-\frac{a^2b^2}{5}=\frac{2ab^2\cdot \:5}{5}-\frac{a^2b^2}{5}

\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}

                 =\frac{2ab^2\cdot \:5-a^2b^2}{5}

                 =\frac{10ab^2-a^2b^2}{5}

Thus,

2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}

Which number would divide the numerator and the denominator of the first
harkovskaia [24]

Answer:

2/2

Step-by-step explanation:

Let the numerator and denominator be x/x

10/12÷x/x=5/6

10x/12x=5/6

x/x=5/6÷10/12

x/x=5/6×12/10

x/x=2/2

Therefore the numbers are 2/2

On a coordinate plane, a line is drawn from point J to point K. Point J is at (1, negative 10) and point K is at point (7, 2). W
nevsk [136]

Answer:

The point that divides the directed line segment from J to K into a ratio of 5:1 is (6, 0), its y-coordinate is 0.

Step-by-step explanation:

We take J as point one, with coordinates (x1, y1) = (1, -10) and K as point two with coordinates (x2, y2) = (7, 2)

The "run" is the change in the x-coordinates:  x2 - x1 = 7 - 1 = 6

The "rise" is the change in the y-coordinates: y2 - y1 = 2 - (-10) = 12

For the partition ratio, let the numerator = a and the denominator = b.

The coordinates of the point P (x, y), which divides the directed line segment from J to K into a ratio of 5:1 is:

x = x1 + a/(a+b)*run

x = 1 + 5/(5+1)*6

x = 6

y = y1 + a/(a+b)*rise

y = -10 + 5/(5+1)*12

y = 0
