Find the number halfway between . 1/2. and . 5/6

1 answer:

Sladkaya [172]3 years ago

7 0

The number in between 1/2 and 5/6 can be determined by obtaining the least common multiple of the two denominators: 2 and 6. the <span>east common multiple is 6. hence 1/2 is equal to 3/6 and 5/6 remains to be. we add the two which is equal to 8/6 and then divide by 2. The answer is 4/6</span>

What is the rate of change between (-8,- 8) and (0,8)

iren [92.7K]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

We need to find thr rate of change (slope) of the line joining these two points ~

$\qquad \sf \dashrightarrow \: m = \dfrac{rise}{run}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 - ( - 8)}{0 - ( - 8)}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 + 8}{0 + 8}$

$\qquad \sf \dashrightarrow \: m = \cfrac{16}{8}$

$\qquad \sf \dashrightarrow \: m = 2$

Slope of the line (m) joining the two points is 2 ~

X + x2 - 5x -5 = 0<br> state the possible rational zeros and find all the zeros of the polynomial

Mariulka [41]

Answer:

<em>The zeros of the polynomial are -1 and 5</em>

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

The standard representation of a quadratic equation is:

$ax^2+bx+c=0$

where a,b, and c are constants.

Solving with the quadratic formula:

$\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have the following equation to solve:

$x+x^2-5x-5=0$

Before attempting to solve it, we must simplify the equation.

Collecting like terms and reordering:

$x^2-4x-5=0$

Here: a=1, b=-4, c=-5

The discriminant of this quadratic equation is:

$d=b^2-4ac$

$d=(-4)^2-4(1)(-5)=16+20=36$

Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.

Applying the formula:

$\displaystyle x=\frac{4\pm \sqrt{36}}{2(1)}$

$\displaystyle x=\frac{4\pm 6}{2}$

Dividing by 2:

$x=2\pm 3$

Separating both roots:

x = 2 + 3 = 5

x = 2 - 3 = -1

The zeros of the polynomial are -1 and 5
