Answer:
a = - 1, b = - 3, c = - 5, d = - 6
Step-by-step explanation:
Substitute the appropriate values of x into the equation and evaluate
x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a
x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b
x = 1 : y = - 1 - 4 = - 5 → c
x = 2 : y = - 2 - 4 = - 6 → d
Answer: Marked Prixe = Rs. 1800
Step-by-step explanation:
Let the marked price be M
1) A retailer allowed 12% discount and sold a T-shirt at a loss of Rs 16.
SP = 0.88M
CP - SP = 16
CP = 16 + SP
CP = 16 + 0.88M
2) If he had sold it at 10% discount he would have gained Rs 20.
SP = 0.9M
SP - CP = 20
0.9M = 20 + CP
CP = 0.9M - 20
16 + 0.88M = 0.9M - 20
0.9M - 0.88M = 20+16
0.02M = 36
36 = 0.02M
M = 1800
The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)
