8x+6 would still be 8x+6 because you cannot add 6 to 8x. remember, 8x means x, 8 times.

Car park algebra question

Svetllana [295]

You did south, north, correctly

but last one

twice north is 2 times (x+48) or 2x+96

so

s=x
n=x+48
c=4x
s+c>2x+96
subsitute s for x and 4x for c
x+4x>2x+96
5x>2x+96
minus 2x both sides
3x>96
divide both sides by 3
x>32
it cannot be equal to 32 so
the minimum value is 33 spaces in south car park

ki77a [65]

Answer:

7 1/8

4 + 7/8 + 2 + 1/4

4+2=6

7/8 + 1/4=9/8 and 9/8 is equal to 1 1/8

6+1+1/8= 7 1/8

Question:

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x)), and explain what f(g(x)) represents.

f(x) = 2x2 + 16

g of x equals the square root of the quantity 5 x cubed

Answer:

f(g(x))=

Step-by-step explanation:

Given:

f(x) = $2x^2 + 16$

g(x) = $\sqrt{(5x^3)}$

f(x) represents the amount of money Raul earns per ticket

x is the number of tickets he sells

g(x) represents the number of tickets Raul sells per hour

To find:

f(g(x)) = ?

Solution:

f(g(x)) represent the amount Raul earns by selling tickets for x hours

We know,

f(x) = $2x^2 + 16$

f(g(x)) = $2(\sqrt{(5x^3)} )^2 +16$

The square root and power 2 cancel each other

f(g(x)) = $2(5x^3 ) +16$

f(g(x)) = $10x^3 +16$

So at x hours

Raul earns $10x^3 +16$

For example lets assume Raul works for 5 hours, then the amount he earns will be

f(g(x)) = $10(5)^3 +16$

f(g(x)) = 10(125) +16

f(g(x)) = 1250 +16

f(g(x)) = 1266

You can also find the amount Raul earns by

g(x) = $\sqrt{(5(5)^3)}$

g(x) = $\sqrt{625}$

g(x) = 25

Substituting in f(x)

f(g(x)) = f(25)

f(25) = $2(25)^2 + 16$

f(25) = 2(625) +16

f(25) = 1250 + 16

f(25) = 1266

so Raul will be earning 1266 if he sells tickets for 5 hours

Answer:

Step 6 is done by Additive Property of Equality, also known as Compatibility of Equality with Addition, which is defined by the following expression:

$a = b \to a + c = b + c$ , $\forall\,a,b, c\,\in \,\mathbb{R}$

Step-by-step explanation:

Step 6 is done by Additive Property of Equality, also known as Compatibility of Equality with Addition, which is defined by the following expression:

$a = b \to a + c = b + c$ , $\forall\,a,b, c\,\in \,\mathbb{R}$

1) $(7\cdot x - 3) + 3 = (2\cdot x + 7) + 3$ Associative property/Compatibility with addition

2) $7\cdot x + [3 + (-3)] = 2\cdot x + (7 + 3)$ Associative and commutative properties/Definition of subtraction

3) $7\cdot x + 0 = 2\cdot x + 10$ Existence of the additive inverse/Definition of addition

4) $7\cdot x = 2\cdot x + 10$ Modulative property/Result
