Answer:
C. It cannot be factored into a perfect square.
Step-by-step explanation:
Take the square roots of all the numbers present (64, 49, 8) and you will find that 8, the constant, is not a perfect square.
Looks like the system is

We can eliminate
by taking




so that
, and



Substitute
into this last equation and solve for
:




Then



Plug these values into any one of the original equation to solve for
:




Hence the solution is x = 4, y = -3, and z = 2.

Answer:
Given: piece wise function-
f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0
First part of the function does not include x = 0.
In slope-intercept form,
slope(m) = 1
y-intercept = (0,3).
So, the conditions are shown in graphs 1 and 3.
Now, the second part of the function equation passes through origin as the equation is f(x) = 2x.
Correct choice - [B]
