Answer:
4⋅(a⋅2)
2⋅(4⋅a)
8a
Step-by-step explanation:
(4⋅a)⋅2
4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
First set them equal to each other
x+17=-2x+19
Solve the equation then...
3x=2
...and you would find x as 2/3
Plug that answer back in and you will find y=53/3
Hope this helps :-)
Gg easy
divide both sides by 2
t+1=5
minus 1 both sides
t=4
The formula for a vertex form equation is

in which (h,k) represents the vertex
Your equation is in vertex form, if you mpve the -7 to the other side you will get

because you have to add 7 to both sides
based on the equation,
h=10
k=7
(h,k)=(10,7)
your vertex is (10,7)
