3x+2y=8
5x-2y=8
1) Cross out the 2ys and add the rest of the equations together.
2) 8x=16
3) 16/8=2 Therefore, x=2
4) Add 2 into one of the equations (either one)
5)3(2)+ 2y=8
6) 6+2y= 8
7) Subtractionnnnn 8-6=2
8) 2y=2
9) 2/2= 1
10) y=1 x=2 (2,1)
Answer: x ~34.31 (rounded)
-6/5 -35/4 -23/6 = -(72/60 +525/60 +230/60)
= -827/60 . . . . . as an improper fraction
= -13 47/60 . . . . as a mixed number
Answer:
![\sqrt[n]{x^a}=x^{a/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Ea%7D%3Dx%5E%7Ba%2Fn%7D)
Step-by-step explanation:
While the "law"
![\sqrt[n]{x^n}=x](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5En%7D%3Dx)
may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...

Answer:
see explanation
Step-by-step explanation:
To find the zeros let h(t) = 0, that is
t² + 4t + 3 = 0 ← in standard form
(t + 3)(t + 1) = 0 ← in factored form
Equate each factor to zero and solve for t
t + 3 = 0 ⇒ t = - 3 ← smaller t
t + 1 = 0 ⇒ t = - 1 ← larger t
(2)
given a parabola in standard form : ax² + bx + c ( a ≠ 0)
Then the x- coordinate of the vertex is
= - 
h(t) = t² + 4t + 3 ← is in standard form
with a = 1 and b = 4, thus
= -
= - 2
Substitute t = - 2 into h(t) for y- coordinate
h(- 2) = (- 2)² + 4(- 2) + 3 = 4 - 8 + 3 = - 1
Vertex = (- 2, - 1 )
