Which expressions are equivalent to (4⋅a)⋅2 ?
shusha [124]

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

What is the system linear equations?<br> y= -2x+19<br> y=x+17
tester [92]
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 :-)

What is the vertex of this equation Y-7=-1/16(x-10)^2
VLD [36.1K]
The formula for a vertex form equation is
y = a(x - h) + k
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
y =  -  \frac{1}{16} (x - 10) ^{2}  + 7
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)
