Answer: C) x = 7, y = -1
Step-by-Step Explanation:
=> y = -2x + 13 (Eq. 1)
=> 4x + 8y = 20 (Eq. 2)
Substitute value of ‘y’ from Eq. 1 in 2 :-
4x + 8y = 20
4x + 8(-2x + 13) = 20
4x + -16x + 104 = 20
-12x + 104 = 20
-12x = 20 - 104
-12x = -84
12x = 84
x = 84/12
=> x = 7
Substitute value of ‘x’ in Eq. 1 :-
y = -2x + 13
y = -2(7) + 13
y = -14 + 13
=> y = -1
Therefore, x = 7, y = -1 which can be written in an ordered pair as (7,-1).
30 x √30 ÷ (3 x √15)
exact form would be 10√2
Decimal form would be 14.14213562
