Yes
For f(x) to represent a function each value of x from the domain must only map to one unique value in the range, called one-to-one
This is the case here as each value of x maps to one unique value in the range
domain x ∈ {- 5, - 4, 0, 3 }
range y ∈ {0, 2, 10, 16 }
The tangent line is perpendicular to the radius from the center of the circle to the point of tangency.
ΔDCE is similar to ΔDBA
DC/DB=DE/DA
15/50=DE/40
DE=12
Answer:
Every whole number n can be written as a fraction of integers.
Step-by-step explanation:
Every whole number n can be written as a fraction of integers: x=x/1.
If we use 15 as an example, it would be 15 = 15/1. 15/1 is 15.
So whole numbers are rational
Combine like terms
9r+r=10r^2
7b+b=8b^2
10+10r^2+8b^2+4n
X<9
The answer is x<9 because you first subtract 4 from both sides then divide both sides by -3. Which then would give you 9.
