in a sale, the normal price of a hat is reduced by 15%
The sale price of the hat is 20.40 euros.
Work out the normal price of the hat.

Answer:

63 inches

Step-by-step explanation:

We can write a ratio to solve

7 inches        x inches

-------------  = -------------------

1 bracelet      9 bracelets

Using cross products

7*9 = 1x

63= x

63 inches

Answer:

The solution is A. (-2,7) and C. (3,2)

Step-by-step explanation:

x+y = 5 ............(1)

x²+y = 11 ............(2)

_________________________

y = 5-x

x²+(5-x) = 11

x²+5-x-11 = 0

x²-x-6 = 0

x²+2x-3x-6 = 0

(factor statement)

x(x+2)-3(x+2) = 0

(x+2) (x-3) = 0

x+2=0 x-3 =0

x = -2 x = 3

(x1 = -2, x2 = 3)

_________________________

y = 5-x

y = 5-(-2) ............(1)

= 7

y = 5-3 ............(2)

= 2

(y1 = 7, y2 = 2)

_________________________

(x1,y1) & (x2,y2)

(-2,7) & (3,2)

So, A. (-2,7) and C. (3,2) correct

Answer:

3. 3/2

4. -1/3

Answer:

Step-by-step explanation:

We want to look at the given graph to estimate the value of f(5). We found that: f(5) = 2

In the coordinate axis, we can see a blue curve, which represents the function f(x).

To find the value of f(5), first, we need to locate the value x = 5 on the horizontal axis.

Once we find it, we need to move vertically until we meet the curve.

Once we meet the curve, we move horizontally until we meet the vertical axis, that intersection gives the value of the function when evaluated in x = 5.

By this method we can see that: f(5) = 2

The graph of amount Tom owes his friend after a given time, t, is a straight line graph with a negative slope

Please find attached the required example of a possible graph that shows the amount Tom owes his friend

Reason:

Let A represent the amount of money Tom buys the boat with, let x

represent the amount of equal payment made and y represents the

amount Tom owes the friend after a given time, t, we have;

y = A - x·t

Therefore, the slope of the graph formed is -x, the y-intercept of the graph

is A, from which the graph that gives the amount of money, in dollars, Tom

owes his friend, as a function of time, in years can be presented as follows,

using example values;

A = $25,000 (Amount the Tom agrees to buy the boat)

x = $5,000 (Amount Tom pays each year for the boat)

By plugging in the above example values, the attached graph can be drawn using MS Excel

The product of sum and difference of two binomial like (x+y) and (x-y) is x² -  y²

The first number = x

The second number = y

The sum of the two numbers = x + y

The difference of the two numbers = x - y

The product of the sum and the difference = (x+y)(x -y)

Note that the product of the sum and the difference = (x + y)(x - y)

This can be expanded by distributivity as shown below:

(x + y)(x - y) = x² + xy - xy - y²

(x + y)(x - y)  =  x² -  y²

This is the difference of two squares.

Therefore, the product of sum and difference of two binomial like (x+y) and (x-y) is x² -  y²

Answer:

Domain is 3 <x>_-2

Range is 6 <x>_-3 (the lines are supposed to be under the >. it means equal to)

Step-by-step explanation:

First look on the x-axis, is goes from 3 to -2. now look at the colored in dot. that means more than or equal to. So the sign of -2 is x >_ -2. put the 3 on the other side. It stops at three so the sign is > 3. so 3<x>_ -2

Do the same with the y-axis except look up and down instead of left and right. so the numbers are 6 and -3. Use the same method above. this is set builder notation.

Answer:

The answer is $5.55

Step-by-step explanation:

7.41 * 3/4= 5.5575

The present cost will be $9.88.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The amount to give cousin = $7.41

This amount covered 3/4 of the total cost.

Now,

Let the present cost = x

So, We can formulate;

⇒ 3/4 of x = $7.41

Solve for x as;

⇒ 3/4 × x = $7.41

⇒ x = $7.41 × 4 / 3

⇒ x = $9.88

Thus, The present cost will be $9.88.
