Answer: D) The y intercept is (0,1)</h3>
This can be confirmed by plugging x = 0 into the function to find that...
y = (1/2)^x
y = (1/2)^0
y = 1
Recall that any nonzero value to the 0th power leads to 1. So we can say x^0 = 1 as long as x is not zero.

Extra info (optional section):
- We can rule out choice A because negative x values work in the domain. For instance, if x = -1, then it leads to y = (1/2)^x = (1/2)^(-1) = 2. The negative exponent will apply the reciprocal operation to the base fraction.
- Choice B can also be ruled out because the range is y > 0. Or you could note that it is possible to get positive y values smaller than 1/2. Try x = 2 and you'll see it leads to y = 1/4 which is not greater than 1/2.
- Choice C is false as well. The function f(x) = (1/2)^x is decreasing throughout the domain. A graph visually would show this due to it going downhill when moving from left to right. A table of values is a non-visual way to see we have a decreasing function. The table would show that y decreases when x increases.
Solve for x:
Take the root of both sides and solve.

Answer:
No she should add extra lengths
Step-by-step explanation:
The difference between scaled copy and jada drawing is that it is in the ratio
8:4
2:1
that is the scaled copy is twice as large as the jada drawing itself.
So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.
Answer:
i think its x=16 or x=11
Step-by-step explanation:
∠2 = 90 - 42 = 48 degrees
3x degrees = 48 degrees
3x = 48
x = 16
16
It is 2/5...You plug in -4/5 into x and plug 1/3 into y
