Is 8/10 mile longer than 1/2

seropon [69]

Yes because if you find common denominators (in this case, "10") you would have to compare 8/10 to 5/10. 8>5 so 8/10 is longer than 1/2.

Write a polynomial equation of least degree with roots 2, -1 and 4.

Rasek [7]

A polynomial with roots a and b is (x - a)(x - b).

(x - 2)(x - (-1))(x - 4) = 0

(x - 2)(x + 1)(x - 4) = 0

has roots 2, -1, and 4.

What is the standard form equation of the line shown below?

Fantom [35]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, 3) and (1, -3). Substitute:

$m=\dfrac{-3-3}{1-(-2)}=\dfrac{-6}{3}=-2\\\\y-(-3)=-2(x-1)\\\\y+3=-2(x-1)$

The standard form: Ax + By = C. Convert:

$y+3=-2(x-1)$ use distributive property

$y+3=-2x+2$ subtract 3 from both sides

$y=-2x-1$ add 2x to both sides

$\boxed{2x+y=-1}\to\boxed{c.}$

Please help been stuck on this hw question ALLL DAYYYYYY

Answer:

1 5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is $\frac{28}{3} * \frac{1}{6}$ . This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!
