Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 1/2(4)ˣ
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = 1/2(4)³
- Exponents: f(3) = 1/2(64)
- Multiply: f(3) = 32
Reflection: the object is reflected (or "flipped") across a line of reflection, which might be the x-axis, y-axis, or some other line. Dilation: the object stays the same shape, but is either stretched to become larger (an "enlargement") or shrunk to become smaller (a "reduction").
Answer:
X= 2 Y=5
Step-by-step explanation:
Set them equal
-2x+9=4x-3 add -2x to both sides and -3 to both sides
12=6x then divide by 6
x=2
plug in 2 to either equation and solve for Y.
Y=-2(2)+9
Y=5
