Answer:
x=17/2 y=1/6
Step-by-step explanation:
-1(x+3y=9)
1(x-3y=8)
_________
-x-3y=-9
x-3y=8
________
-6y/6=-1/6 y=1/6
x+3(1/6)=9
x+ 1/2=9
- 1/2 - 1/2
x=17/2
Answer:
line of symmetry , x = 3
Step-by-step explanation:
Standard form of quadratic equation is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.
a = 1, b = -6, c = -16
Line of symmetry is ,
The answer is 1/3...I got this question on I-ready and I hate when I don't pass a lesson...hope this will help you guys out.
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
Answer:
The Proof is given below.
Step-by-step explanation:
Given:
LN⊥KM,
KL≅ML
To Prove:
ΔKLN≅ΔMLN
Proof:
In Δ KLN and Δ MLN
KL ≅ ML ....……….{Given i.e Hypotenuse }
LN ≅ LN …………..{Reflexive Property}
∠ LNK ≅ ∠ LNM ……….{ LN ⊥ KM i.e Measure of each angle is 90° given}
Δ KLN ≅ Δ MLN ….{By Hypotenuse Leg Theorem}
....Proved
