Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 1 → (1)
x - 3y = - 11 → (2)
Adding the 2 equations term by term will eliminate the y- term
5x + 0 = - 10
5x = - 10 ( divide both sides by 5 )
x = - 2
Substitute x = - 2 into either of the 2 equations and solve for y
Substituting into (1)
4(- 2) + 3y = 1
- 8 + 3y = 1 ( add 8 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (2, - 3 )
Answer:
9/10
Step-by-step explanation:
3^4/5^4 × 15^4/10^4=x^4/y^4
81/625 × 50625/10000= x^4/y^4
multiply
4100625/6250000=x^4/y^4
break it down by dividing it by 5
820125/1250000
divide by 5
164025/250000
divide by 5
32805/50000
divide by 5
6561/10000 = x^4/y^4
4√6561/4√10000=x/y
9/10= x/y
Answer:
Helppppppp Neeeeeeeeded asapppppp
Step-by-step explanation:
Answer:
because l1//l2 => z + 65 = 180
y + 65 = 90
x + 65 = 90
<=> z = 115
y = 25
x = 25
