The slope is -1.

because the slope formula gives you (-1-4)/(2-(-3)) which is -5/5 which also is -1

Rewrite 8x - 7 as the product of two factors

kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example: 4 can be broken into 2 factors---2 and 2. 2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor. A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So: 8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

scoray [572]

Answer:

$d = |- 5- 9|$

Step-by-step explanation:

Given

$Initial = 9^\circ F$

$Final = -5^\circ F$

Required

Determine the difference

Represent this with d.

d is calculated using

$d = |Final - Initial|$

The equation becomes

$d = |- 5- 9|$
