Answer:

(x,y)=(5,-1)

Step-by-step explanation:

1. 2x+y=9 ---> y=9-2x

2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.

3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1

Algebra Help Please!!!

Vesnalui [34]

Answer:

Step-by-step explanation:

The given function can be rewritten as y = ∛(27)*∛(x-3) - 5, or y = 3∛(x-3) - 5.

The basic (parent) function is y = ∛x. Graph this.

Next, perform a vertical stretch on this parent function: every y value will be 3 times its previous value.

Next, translate this graph 3 units to the right.

Last, translate this new graph 5 units downward.
