Jill , meg and Beth are sisters. Jill is 2 yrs younger than meg . Beth is half as old as meg . let m represent megs age.Write two other algebraic expressions based on this situation . Tell what expression represents, and what the variable stands for in each sentence
Answers
Answer:
The algebraic expressions are
x = m + 2
Step-by-step explanation:
As given
Jill , meg and Beth are sisters.
Let m is represented the age of the meg.
Let x is represented the age of the jill.
Let y is represented the age of the Beth.
As given
Jill is 2 yrs younger than meg .
Thus
x = m + 2
As given
Beth is half as old as meg.
Thus
Therefore the algebraic expression are
x = m + 2
meg=m
beth=b
jill is 2 years younger than meg
therefor if we add 2 to jill age we get meg's age
j+2=m
beth is 1/2 as old as meg
therefor 1/2 of megs age=beth's age
b=1/2m
j+2=m
b=1/2m

Answer:
( f o g) (x) = 3x²+5
Step-by-step explanation:
We have given two functions :
f (x) = 3x + 2
g(x) = x² + 1
We have to find ( f o g) (x) =?
( f o g) (x) = (f(g(x))
Putting the values of functions in above formula.
( f o g) (x) = 3(x²+1)+2
( f o g) (x) = 3x²+3+2
Adding like terms,we have
( f o g) (x) = 3x²+5
( f o g) (x) = 3x²+5 is the answer.
Answer: (f o g)(x)=
Step-by-step explanation:
To solve this problem you must apply the following proccedure:
(f o g)(x) indicates that you must substitute the function g(x) into the function f(x).
Therefore, you have:
(f o g)(x)=
Now, you must simplify it, as it is shown below:
Apply the distributive property and add the like terms:
(f o g)(x)=
(f o g)(x)=

First, cancel 2 on both sides. / Your problem should look like:
Second, expand. / Your problem should look like:
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like:
Fourth, add 3d to both sides. / Your problem should look like:
Fifth, add d + 3d to get 4d. / Your problem should look like:
Sixth, divide both sides by 4. / Your problem should look like:
Answer as fraction:
Answer as decimal:
2+d=2−3(d−5)−2
2+d=2+(−3)(d)+(−3)(−5)+−2(Distribute)
2+d=2+−3d+15+−2
d+2=(−3d)+(2+15+−2)(Combine Like Terms)
d+2=−3d+15
Add 3d to both sides.
d+2+3d=−3d+15+3d
4d+2=15
Subtract 2 from both sides.
4d+2−2=15−2
4d=13
Divide both sides by 4.
4d/4=13/4
d=13/4
