I assume you want to know a permutation about how many ways they can be in the final set-up.
Order matters, which is why this is a permutation.
Formula: P(n, r) =
where the permutation is
, with P for permutation.
Plug in:
4!/(4-2)!
4!/2!
(1 x 2 x 3 x 4)/1 x 2
(3x4)/1
= 12
12 ways.
Answer:
Step-by-step explanation:
$2800 - $750 = $2050
$2050 - $500 = $1550
$750 rent
$500 vacation savings
$1500 spending money
Answer:
10π inches
Step-by-step explanation:
C = 2πr
C = 2π(5)
C = 10π ≈ 31.42
To choose the graph, we must make sure that it satisfies both equations of the system simultaneously.
We have then:
a line includes points 0 comma 4 and 3 comma 5
Verifying:
(0, 4)
(0) - 3 (4) = -12
0-12 = -12
-12 = -12
(3, 5)
2x - y = 1
2 (3) - (5) = 1
6-5 = 1
1 = 1
answer
The graph that matches the system of equations is
a line includes points 0 comma 4 and 3 comma 5
Answer:
x = 17/4 = 4.25
Step-by-step explanation:
We assume your multiplication symbol (×) is intended to be a variable (x).
Simplifying, we have ...
17 -10x +45 = 6x -10 +4
68 = 16x
68/16 = x = 17/4 = 4.25
__
<em>Check</em>
17 -5(2(4.25) -9) = -(-6(4.25) +10) +4
17 -5(8.50 -9) = -(-25.5 +10) +4
17 -5(-0.5) = 15.5 +4
17 +2.5 = 19.5 . . . . . . true
