Answer:
2
Step-by-step explanation:
The solutions are ...
p +m|x +n| = k . . . . . given
m|x +n| = k -p . . . . . . subtract p
|x +n| = (k -p)/m = (p -k)/-m . . . . . . must have (p-k)/-m ≥ 0
x = -n ± (p -k)/-m
For the given conditions, m < 0, p > k, we are guaranteed that (p-k)/-m > 0, so there are 2 solutions.
Answer:
LEAST DIFFICULT: B
MOST DIFFICULT: I
Step-by-step explanation:
LEAST DIFFICULT:
The easiest systems of equations to solve are ones in which x or y is equal to just a number , because in this case, you can just sub in that number in the other equations. Though not the only one, B is an example of this.
MOST DIFFICULT:
More difficult systems of equations to solve are the ones with different amounts of x and y as it requires more computation. Set I is an example of this
Are you suppose to find x or y? or both?
Step-by-step explanation:
6x - 15 = 75, 6x = 90, x = 15.
2(2x - 1) = 46, 2x - 1 = 23, x = 12.
x + (x - 10) = 26, 2x = 36, x = 18.
5x - 3x = 10, 2x = 10, x = 5.
Hence the equations
in increasing order of x-values are:
5x - 3x = 10,
2(2x - 1) = 46,
6x - 15 = 75, and
x + (x - 10) = 26.
Answer: $10
Step-by-step explanation:
$4/40 golf balls = $1/10 golf balls
$1/10 = x/100, x=100/10, x=$10
