Answer: 13 units
Step-by-step explanation:
AB=
|A-B|=
|(-1, -6)-(-1, 7)|=
|(-1-(-1), -6-7)|=
|(-1+1, -13)|=
|(0, -13)|=
|-13|=13 units
15.12 miles
—————-
6.3 hours
Divide both miles and hours by 6.3
15.12 divided by 6.3 = 2.4 miles
6.3 divided by 6.3 = 1 hour
Answer:
2.4 miles
—————
1 hour
Answer:
- -5, -18
- -5x -18x
- (x -3)(6x -5)
Step-by-step explanation:
a) The factors of 90 are ...
90 = (-1)(-90) = (-2)(-45) = (-3)(-30) = (-5)(-18) = (-6)(-15) = (-9)(-10)
The sums of these factors are -91, -47, -33, -23, -21, -19.
The factor pair with the sum of -23 is of interest here. Those factors are ...
-5, -18
__
b) -23x = -5x -18x
__
c) The rewritten expression is ...
6x^2 -5x -18x +15
(6x^2 -5x) -(18x -15) . . . . group into pairs
x(6x -5) -3(6x -5) . . . . . . .factor each pair
(x -3)(6x -5) . . . . . . . . . . factor out the common factor (6x -5)
