Answer:

y-7 = -4(x+1)

Step-by-step explanation:

The point slope formula is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y-7 = -4(x--1)

y-7 = -4(x+1)

11B. Long Beach Towing Company charges $40 plus $5 per mile to

gavmur [86]

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

$L(x) = 40 + 5x$

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

$F(x) = 70 + 2x$

After how many miles the charges for the two companied will be the same?

This is x for which:

$L(x) = F(x)$

$40 + 5x = 70 + 2x$

$5x - 2x = 70 - 40$

$3x = 30$

$x = \frac{30}{3}$

$x = 10$

The charges will be the same after 10 miles.

Use the distributive property to remove the parentheses. Simplify your answer as much as possible.

goldenfox [79]

10x^3(8x^3+3x)

([10x^3 x 8x^3]+ [10x^3 x 3x])

80x^6+ 30x^4

•this is as simplified as it gets; it isn’t possible to add or subtract numbers with different exponents.
