1647. 1 hour=60 minutes. John can mow 247 square feet per minute, so he can mow 60*247=14820 square feet per hour. 1 yard=3 feet, so 1 square yard =3^2=9 square feet, so in the same duration of time, John can mow 14820/9=1647 square yards (approximately) per hour.

Given the equation 2X +4/3 Y equals one and Y -9/13 x=9 by what Vector would you multiply the first equation so that combining t

Mila [183]

Answer: Option B

B. $\frac{9}{26}$

Step-by-step explanation:

We have the following equations:

$2x + \frac{4}{3}y = 1$ (1)

$y -\frac{9}{13}x=9$ (2)

Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.

Then we must multiply the number "a" by a value z such that when adding $az + b$ the result is zero. $a = 2$

$b = -\frac{9}{13}$

So

$2z-\frac{9}{13} = 0$

We solve the equation for z

$2z=\frac{9}{13}$

$z=\frac{9}{26}$

The first equation must be multiplied by a value of $\frac{9}{26}$

Is g(x)= (x-2)(x-9)(x-1) the factored form of f(x)=x^3+8x^2-11x-18

strojnjashka [21]

We can check to see if (x - 2)(x - 9)(x - 1) is the factored form of x^3 + 8x^2 - 11x - 18 by using foil.

(x - 2)(x - 9)(x - 1)

(x - 2)x^2 - x - 9x + 9

Combine like terms.

(x - 2)x^2 - 10x + 9

FOIL again.

x^3 - 10x^2 + 9x - 2x^2 + 20x - 18

Combine like terms.

x^3 - 12x^2 + 29x - 18
