5x+2y=-4 -x+2y=8 Solve the system

1 answer:

6 0

Subtract the second equation from the first.
.. (5x +2y) -(-x +2y) = (-4) -(8)
.. 6x = -12
.. x = -2

.. -(-2) +2y = 8
.. 2y = 6
.. y = 3

The solution is (x, y) = (-2, 3).

If g(x)= x=2 and h(x) = 4 - X, what is the value of (gºh)(-3)?

navik [9.2K]

The required value of (g°h)(-3) is 5.

Step-by-step explanation:

Given,

g(x)= x-2 and h(x) = 4 - x

To find (g°h)(-3)

Now,

(g°h)(x) = g(h(x))

= g(4-x)

= (4-x)-2 = 2-x

So,

(g°h)(-3) = 2-(-3) = 5 [ putting x=-3]
