Use substitution to answer the system 2x-3y=17 x=2y+10 x= y=

1 answer:

7 0

First, you substitute each x in the first equation- 2(2y+10)-3y=17
Next, simplify - 4y+20-3y=17
y+20=17
y=-3

Next, substitute the y in for the second equation, x=2y+10
x=2(-3)+10
x=-6+10
x=4
ANswer:
x=4
y=-3
Hope this helps!

Answer:

Step-by-step explanation:

First, start out with the parent function:

$y = b^{x}$

Now, we look at the transformations, and make the equation.

We see that the graph shifted down 4 units, since the graph's horizontal asymptote is at y = -4.

$y = b^{x} - 4$

We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),

Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.

This is the answer:

$y = 3^{x}-4$
