1 answer:
Ordered pairs :
A. (4,2)
B. (5,-2)
C.(0,-1)
D.(-3,1)
E. (2,7)
F. (8,4)
Answer:
A, B, F are solution to the inequality
Step-by-step explanation:
5x - y > 4
To obtain the pairs which are solution to the linear inequality ; we plug in each orders pair of values into the inequality :
A.)
(4,2)
5x - y > 4
5(4) - 2 > 4
20 - 2 > 4
18 > 4 - - - - - - - True
B.
(5, -2)
5x - y > 4
5(5) - (-2) > 4
25 + 2 > 4
27 > 4 - - - True
C.
(0, -1)
5x - y > 4
5(0) - (-1) > 4
1 > 4 - - - - - - - Untrue
D.
(-3,1)
5x - y > 4
5(-3) - 1 > 4
-15 - 1 > 4
-16 > 4 - - - - - > Untrue
E.
(2,7)
5x - y > 4
5(2) - 7 > 4
10 - 7 > 4
3 > 4 - - - - Untrue
F.
(8,4)
5x - y > 4
5(8) - 4 > 4
40 - 4 > 4
36 > 4 - - - - - - - True

Answer:
profit : RS 150 and profit % : 3%
Step-by-step explanation:
for profit 10% for loss 4%
s.p will be 2750. s.p will be 2400
Total s.p : 2750 +2400. total s.p : 5150
profit = s.p-c.p. profit%=?
=5150-5000. profit = p /c.p × 100
=150 = 150/5000×100
= 3%
Answer:
(1,-6)
Step-by-step explanation:
4x - y = 10
4x -(-6) = 10
4x + 6 = 10
- 6 - 6
4x = 4
/4 /4
x = 1
(x, y) -> (1,-6)
Check your answer:
4x - y = 10
4(1) - (-6) = 10
4 + 6 = 10
10 = 10
This statement is correct
Hope this helps!
Answer:
sure?
