B: –24
C: –15
D: –6
Answer:
The correct answer is D. -6
Step-by-step explanation:
f(x) = 3x + 3
g(x) = 3x + 3
h(x) = x + 3
We need to find : [g o f o h](–5)
⇒ [g o f o h](–5)
⇒ [g o f]h(-5)
⇒ [g o f](-5 + 3)
⇒ [g o f](-2)
⇒ [g]f(-2)
⇒ [g](3 × -2 + 3)
⇒ [g](-6 + 3)
⇒ g(-3)
⇒ 3 × -3 + 3
⇒ -9 + 3
⇒ -6
Therefore, The correct answer is D. -6
Answer:
140
Step-by-step explanation:
What is 20 percent (calculated percentage %) of number 700? Answer: 140.
b.4n - 15 = 101
Answer:
Option a and b both are correct.
Step-by-step explanation:
We have been given the information that is: n is added to 15 less than 3 times itself.
The result is 101.
So, the number is 15 less than 3 times to itself means: 3n-15
And n is added to it that means:
n+(3n-15)
And its result is 101 so,
n+(3n-15)=101
After simplification of above expression gives:
4n-15=101.
Therefore, Option a and b both are correct.
A) an = 0.45 - 0.75n
B) an = 0.45 + 0.50n
C) an = -0.45 + 0.75n
D) an = -0.45 - 0.75n
