Answer:

\boxed{x = -4~~and~~y = 0}

.

Step-by-step explanation:

Use elimination

-3x + 5y = 12

<u>7x - 5y = -28  </u>+

4x = -16

x = \frac{-16}{4}

x = -4

.

Subsitute the value of x to one of equations

-3x + 5y = 12

-3(-4) + 5y = 12

12 + 5y = 12

5y = 12 - 12

5y = 0

y = \frac{0}{5}

y = 0

.

Happy to help :)

Consider the function f(x)= x^2 and the function g(x) shown below. how will the graph of g(x) differ from the graph of f(x)
malfutka [58]

Answer:

f(x) = x^2

g(x) = 4*x^2​

=> For a value of x, the g(x) is 4 times larger than f(x).

=> g(x) is the stretched version of f(x) with stretched ratio = 4).

=> Option D is correct

Hope this helps!
