You do not need to know the variable to solve the equation

If the variables on each side are the same, then you simply ignore them
For example

n3*3 = n81/9
You do not need to know n to solve the equation

Given f(x)=4x+5 and g(x)= x^2+x; find (f∘g)(-5) Please show all steps thank you

Greeley [361]

Answer:

$(f\circ g)(-5)=85$

Step-by-step explanation:

We are given:

$\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x$

And we want to find:

$(f\circ g)(-5)$

This is equivalent to:

$\displaystyle =f(g(-5))$

So, we will evaluate g(-5) first, which yields:

$\displaystyle g(-5)=(-5)^2+(-5)=25-5=20$

So:

$=f(g(-5))=f(20)$

Then:

$\displaystyle f(20)=4(20)+5=80+5=85$

Therefore:

$(f\circ g)(-5)=85$

Let Jenny = J

Let Mica = M

J = M + 4

Now you have to represent 5 years ago

J - 5 = 2*(M - 5)

J - 5 = 2M - 10 Substitute J = M + 4 Into this equation

M + 4 - 5 = 2M - 10 Combine terms on the left

M - 1 = 2M - 10 Add 10 to both sides

M - 1 + 10 = 2M Combine one the left

M + 9 = 2M Subtract M from both sides

9 = 2M - M

9 = M Answer Miki

J = M + 4 Substitute Miki's age for M

J = 9 + 4 Answer Jenny

J = 13

Answer:

Jenny = 13

Mika = 9
