9. Extend Your Thinking Georgette bought some craft items. The silk flowers cost three times as much as the ribbon. The ribbon cost two times what the foam cost. The vase cost $12, which was three times as much as the foam. How much did the silk flowers cost?

Answer:

59.40

Step-by-step explanation:

Yes, This situation represent a function.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The cost of each car = $40

The cost of each person = $8.50

Let the number of car = x

The number of persons in a car = z

Then, Total cost of car = $40x

Total cost of persons in car = $8.50z

So, Total cost (y) = $40x + $8.50z

Thus, The function for this situation is;

y = $40x $8.50z

Clearly, This is a linear function with three variable.

Thus, This situation represent a function.

Answer:

it's greater than one so it's value is not negative

and 3+4 is 7

so x is greater then 4 but less than 7

so it's b the correct option

Answer:

D. -2 < x < 1

Step-by-step explanation:

1 < x + 3 < 4

=

{1 < x + 3

{x + 3 < 4

=

{ 1 + ( -3 ) < ( x + 3 ) + ( -3 )

{ ( x + 3 ) + ( -3 ) < 4 + ( -3 )

=

{ 1 - 3 < x + 3 - 3

{ x + 3 - 3 < 4 - 3

=

{ -2 < x

{ x < 1

=

{ x > - 2

{ x < 1

Hence, the answer would be : -2 < x < 1

Step-by-step explanation:

divide 7.2 by 2 so you have an hourly rate. Then you have 3.6, multiply that by 7 to get 25.2. Assuming its not in km cause that wouldn't make sense you would just have to convert it into whichever unit it would take

The function operation g( x - 1 ) of the function g( x ) = −4x − 1 is -4x + 3.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

To find g( x - 1 ), replace all the occurrence of x with ( x - 1 ) in the function and simplify.

g( x ) = −4x − 1

g( x - 1  ) = −4( x - 1 ) − 1

Simplify by distributive property

g( x - 1  ) = −4( x - 1 ) − 1

g( x - 1  ) = x( -4 ) - 1( -4 ) - 1

g( x - 1  ) = -4x + 4 - 1

g( x - 1  ) = -4x + 4 - 1

Add 4 and -1

g( x - 1  ) = -4x + 3

Therefore, the function operation g( x - 1 ) is -4x + 3.

The system of inequalities is:

y < -4*x + 1

y ≥ (1/2)*x + 1

Here we can see two lines, one dashed that passes through (0, 1) and (-1, 5), then the slope is:

s = (5 - 1)/(-1 - 0) = -4

And the y-intercept is 1, then the inequality is:

y < -4*x + 1

The other line is solid, and the shaded region is above the line.

This line passes through (0, -1) and (2, 0), then the slope is:

s = (0  + 1)/(2 - 0) = 1/2

So the inequality is:

y ≥ (1/2)*x + 1

a. Solving for 'd' as the subject of formula gives d = P/64

b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet

A function can be defined as an expression, law or rule that shows the relationship between two variables.

These variables are namely;

Given the function as;

P = 64d

Where;

Now, let's make the variable 'd' the subject of formula

Divide both sides of the equation with the coefficient of the variable 'd' which is 64. This is done so that the variable stands alone.

We have;

P/64 = 64d/64

d = P/ 64

If the pressure, P equals  672 pounds per square foot

Substitute the value of the variable into the formula, we have;

d = P/64

Then,

d = 672/64

Find the quotient

d = 10. 5 feet.

Thus, the value is 10. 5 feet

Answer:

(2)  The 3 was not distributed correctly.

3(x + 4) is the same as 3(x) + 3(4)  Which is 3x + 12 not 3x + 4

Step-by-step explanation:

Answer: The error was at the first step since 4 was never multiplied by 3, therefore the final answer would be incorrect.  

Step-by-step explanation:  3(x + 4) = 13

multiply 3 by everything in the parenthesis, so

3x + 12 = 13

subtract 12 from each side.

The total money Isabella spent on tickets will be $1362.48

In the given question, it is stated that Isabella bought a total of 84 Tickets. Each of the tickets she bought cost $16.22. We have to find out the total amount that she spent on buying tickets for everyone. From this given situation we know:

The cost of one ticket: $16.22

Total number of tickets: 84

From this formula, we can calculate the total amount spent

Total Amount = Total ticket * cost of one ticket

Putting values in this formula, we get:

=> Amount = cost*number

=>  Amount = 16.22*84

=>  Amount = 1362.48

Hence, the Total amount that she spent on Tickets will be $1362.48
