Answer is (-3,1) x=-3 y=1
o-na [289]4 years ago
3 0

Answer:

X=-3     y=1

Step-by-step explanation:

1)  multiply the second equation by 3 to subtract it from the second

3(x+6y)=(3)3

3x+y=-8

-

3x+18y=9

—-------------

-17y=-17

Y=1

Substitute 1 in equation 2

X+6(1)=3

X+6=3

X=-3

If f(x)=x^2 is horizontally compressed to g(x), which could be the equation of g(x)?
leva [86]

For the definition of <em>horizontal</em> compression, the function f(x) = x² is horizontally compressed to the function g(x) = (k · x)², for 0 < k < 1.  

<h3>How to find the resulting equation after applying a compression</h3>

Here we must narrow a given function by a <em>rigid</em> operation known as compression. <em>Rigid</em> transformations are transformations in which <em>Euclidean</em> distances are conserved. In the case of functions, we define the horizontal compression in the following manner:

g(x) = f(k · x), for 0 < k < 1     (1)

If we know that f(x) = x², then the equation of g(x) is:

g(x) = (k · x)², 0 < k < 1

For the definition of <em>horizontal</em> compression, the function f(x) = x² is horizontally compressed to the function g(x) = (k · x)², for 0 < k < 1.

Which point is one the graph of f(x) = 2 * 5^x?
marusya05 [52]

Answer:

(0,2)

Step-by-step explanation:

I'm going to assume you meant Which point is ON the graph of f(x) = 2 * 5^x?

In order to do this question, all you need to do is pick any number as x. Lets pick 0 in this case.

f(x) = 2 * 5^x

f(0) = 2*5^0

= 2*1

= 2

So one point on the graph would be (0,2)

Why?

Because remember with functions, the f(x) can be swapped out with y, so when x = 0, y = 2.
