F(x)=x^2
x=-1→f(-1)=(-1)^2→f(-1)=1
g(x)=1/(2x+3)
g(f(-1))=g(1)→x=1→g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5
Answer: Option C.) 1/5
Answer:
Mikhail is 50 years old.
Step-by-step explanation:
Let m represent how old Mikhail is.
110 = (m + 10) + m
Combine equal variables.
110 = 2m + 10
Get the variable alone by cancelling out the 10.
110 - 10 = 2m
Simplify.
100 = 2m
Divide.
m = 50
Answer:
1.728 × 106 pounds of vegetation
Step-by-step explanation:
From the question, each elephant eats 2.16 × 105 pounds of vegetation per year.
Since there are eight elephants, it will cost a total of 8× 2.16 × 105 pounds of vegetation per year = 1.728 × 106 pounds of vegetation
Step-by-step explanation:
this is your answer....
If the '7t' is supposed to be '7y', then the answer is below
(4y+8)-(7y-12)=11
distribute the negative into the second parenthesis
4y+8-7y+12=11
combine like terms
-3y+20=11
subtract the 20 from both sides
-3y=-9
divide by -3 on both sides
y=3
if it is supposed to be '7t', I'm not sure if there's enough information
