<h3>
Answer: D) 4</h3>
Explanation:
Start at the point (-1,-4). In order to move to (0,0), we must do the following two steps:
- Move 4 units up
- Move 1 unit to the right
This indicates slope = rise/run = 4/1 = 4.
You could use the slope formula to get this same result.
Answer:
Option (2)
Step-by-step explanation:
Given functions are,
c(x) = 
d(x) = x + 3
Equation of the composite function will be,
(cd)(x) = c(x) × d(x)
= 
= 
This function is defined only when denominator is not equal to zero.
(x - 2) ≠ 2
Therefore, for real numbers except x = 2 will be the domain of the composite function.
Option (2) will be the answer.
Answer:
-3, -1
Step-by-step explanation:
Answer:
4/5
Step-by-step explanation:
Two are white.
10 total marbles.
10 - 2
8 are not white.
8/10
Simplify or reduce.
⇒ 4/5
Given that f(x) = 2x + 11: if f(x) = y = 21, then 21 = 2x + 11, and so 10=2x and x=5.
Thus, f(5) = 2(5) + 11 = 21; (5,21) is a point on the graph of f(x).
If that is so (which it is), then (21,5) is a point on the graph of the inverse function, and 5 is the appropriate output value.
