A system of equations is a set of two or more equations that share two or more unknowns. The solutions to a system of equations are all the values that make all of the equations true, or the points where the graphs of the equations intersect.
We can solve a system of linear equations through graphing, substitution and linear combination. Systems of nonlinear functions, such as quadratic or exponential equations, can be handled with the same techniques.
Answer:
3/5
Step-by-step explanation:
hope i helped :)
Its helpful because it gives you the number to put in and to find the unit rate
Ok I’ll follow you but I’m not active on it
Step-by-step explanation:
it says f(-4).
so, x = -4.
into what function segment is this "falling" ?
well, into the x < 3 segment, right ? because -4 < 3.
so, we need to use
f(x) = x² - 5
f(-4) = (-4)² - 5 = 16 - 5 = 11
