Answer:
-1x - 1
Step-by-step explanation:
the factor of x is the slope of the line in the form of y/x.
it simply says how many units y changes for a given change of x.
in our diagram we can see that when x changes one unit to the right (positive), y changes 1 unit down (negative).
so, the slope or factor of x = -1/1 = -1
and when x=0, y=-1.
so, the constant offset in the line equation is -1 too.
so, it is
y = -x - 1
or as explicit factor for x
y = -1×x - 1

Answer:
9.25≤x≤64.15
Step-by-step explanation:
The smallest amount would be 5 of the least priced item
5 * 1.85 =9.25
The largest amount would be 5 of the greatest priced item
5 * 12.83 =64.15
9.25≤x≤64.15
Answer:
If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.
, but 
.
However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.
Example:
This is simply
.
It is a multiple of 2 twice.
Consecutive numbers means that they are one after the other (i.e. 1, 2, 3 are consecutive numbers). The square of a number signifies the product of this number times itself (i.e. 2 times 2 = 4, so 4 is the square of 2). If these squares differ by 25, then when they are subtracted from one another, the difference will be 25:
12 x 12 = 144
13 x 13 = 169
169 - 144 = 25
