Jenny wants to rent a truck for one day. She contacted two companies. Laguana's Truck Rentals charges $20 plus $2 per mile. Salv

Anna71 [15]

Answer:

20 miles.

Step-by-step explanation:

Let m be number of miles.

Laguana's Truck Rentals charges $20 plus $2 per mile.

Total cost of Laguana's Truck = $20+2m$ .... (1)

Salvatori's truck rentals charges $3 per mile.

Total cost of Salvatori's truck = $3m$ ... (2)

We need to find the number of hours after that the total cost for both companies will be the same.

$3m=20+2m$

$3m-2m=20$

$m=20$

Therefore, after 20 miles the total cost for both companies will be the same.

8) 2(5-6n): 10n - 166<br>how do you solve this?

Zina [86]

Answer:

n=8

Step-by-step explanation:

2(5-6n)=10n-166

1) Distribute the 2 to 5 and -6n:

10-12n=10n-166

2) Add 166 to both sides:

176-12n=10n

3) Add 12n to both sides:

176=22n

4) Divide both sides by 22:

n=8

✺ Quadratic polynomials can be factored using the transformation $ax^2+bx+c=a(x-x_{1})(x-x_{2} )$ , where $x_{1}$ and $x_{2}$ are the solutions of the quadratic equation $ax^2+bx+c=0$ :

$-x^2+6x=0$

✺ All equations of the form $ax^2+bx+c=0$ can be solved using the quadratic formula:

$-b=\frac{+}\\\sqrt{b^2-4ac}\\~~~~~~~~~~~~~2a$

✺ The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction:

$x=\frac{\sqrt{-6\frac{+}\\\sqrt{6^2}}}{2(-1)}$

✺ Take the square root of $6^2$ :

$x=\frac{\sqrt{-6\frac{+}\\{6}}}{2(-1)}$

✺ Multiply $2$ times $-1$ :

$x=\frac{\sqrt{-6\frac{+}\\{6}}}{-2}$

✺ Now solve the equation $x=\frac{\sqrt{-6\frac{+}\\{6}}}{-2}$ when ± is plus. Add $-6$ to $6$ :

$x=\frac{0}{-2}$

✺ Divide $0$ by $-2$ :

$x=0$

-OR-

✺ Now solve the equation $x=\frac{\sqrt{-6\frac{+}\\{6}}}{-2}$ when ± is minus. Subtract $6$ from $-6$ :

$x=\frac{-12}{-2}$

✺ Divide $-12$ by $-2$ :

$x=6$

✺ Optional : Factor the original expression using $ax^2+bx+c=a(x-x_{1})(x-x_{2} )$ . Substitute $0$ for $x_{1}$ and $6$ for $x_{2}$ :

$-x^2+6x=-x(x-6)$

✩ Answer:

✺ <u>Factored Form</u>: $x(x-6)$

✺ <u>Exact Form</u>: $x=6$

✺ <u>Graph Point Form</u>: $x=(6,0)$
