Answer:
x=-17 y=-14 (-17,-14)
Step-by-step explanation:
-2(y-3)+3y=-8
-2y+6+3y=-8
combine like terms
y+6=-8
y=-14
next plug in y to find x
x=-14-3
x=-17
Please answer this asap I need the answer..............
78-46 equals 32 70-48 equals 22
In both cases you may well benefit from graphing the functions.
Do you recognize f(x) = (x + 1)^2 - 1 as a quadratic function, whose graph is that of a parabola that opens up? By comparing this to y = a(x-h)^2 + k, we see that a=1, h= -1 and k = -1. The vertex is at (h,k), which here is the point (-1, -1). This is the minimum value of the function. Thus, the range of this function is [-1, infinity).
Now for the function f(x) = 7x - 11: This is a linear function whose graph is (surprise!) a straight line. When x increases, y increases, without limits to either. Similarly, when x decreases, y decreases.
Thus the range includes all real numbers: (-infinity, infinity).
