Answer: x ≥ 5</h3>
Since x is a natural number, this is the same as saying x > 4
=======================================================
Explanation:
Let's solve for x
Since 
, this means x is a natural number and a value from the set {1,2,3,4,...} aka the set of positive whole numbers. Zero is not in the set of natural numbers.
So we'll need to round that 4.667 to the nearest whole number to get x ≥ 5
If we were to replace x with anything from the set {5, 6, 7, 8, ...}, then that would make the original inequality to be true.
The notation x ≥ 5 and x > 4 are identical when x is a natural number, because we're describing the same solution set of any whole number 5 or larger.
Answer:
9. No
10. Yes
Step-by-step explanation:
The first one is not, since you have (3, 3) and (3, 9). In a function, each x maps to a single y.
The second one is since every x appears only once.
Answer:
C. 62.8 units
Step-by-step explanation:
Use distance formula or Pythagorean theorem.
Pythagorean-
6^2+8^2= radius^2
100= radius^2
10= radius
radius= r
Use circumference formula.
C=2pir
C=2pi10
C=62.83
Answer:
1. initial point is (2, 4)
reflected point is (-2, 4)
the coordinates are similar because they involve the same numbers, however, with the reflection across the Y axis, the X point became negative.
2. initial point is (2, 4)
reflected point is (2, -4)
again, same numbers but the X value becomes negative
Hope this helps!
