Answer:
-14 x
Step-by-step explanation:
Simplify the following:
-4 x - 10 x
-4 x - 10 x = -14 x:
Answer: -14 x
Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
Answer:
72/107
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-1 -71)/(-100-7)
= -72/-107
= 72/107
The answer is b
If you go backwards on a number line, you are subtracting--which is the same as adding a negative.
First you go backwards 3 numbers, and then to get to -7, you went down (decreased) by 4 more, or subtracted 4 (added a negative 4)
