The minimum number of $0.10 stamps he needs to use is 1 stamp.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

let x represents the number of $0.44 cent stamps

and, y represents the number of $0.10 cent stamps

Ori uses all 3 of the $0.44 cent

=0.44x3

= 1.32

Then, 1.47-1.32= 0.15

We have at least 2 dimes for the equation

=0.44(3)+0.10(2)≥1.47

= 1.32+0.20≥1.47

= 1.52≥1.47

Then,  number of $0.10 stamps he needs to use

= 0.15/ 0.10

= 1.5

= 2 or 1 stamps

If two rectangles are congruent, it means they are the exact same shape and size.

I have uploaded an image with this answer. In the image, you can see two rectangles with the same perimeter. However, they are not congruent because they are not of the same size (even though they are of the same shape - a rectangle).

Hence, two rectangles may not be congruent if they have the same perimeter.

The value of x and y from the equation is 1/6 and 5/6 respectively

x = 1/6

y = 5/6

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be A

11x - 7y = -4   be equation (1)

Let the second equation be B

-14x - 2y = -4   be equation (2)

On simplifying , we get

Multiply equation (2) by 7 , we get

-98x - 14y = -28   be equation (3)

Multiply equation (1) by 2 , we get

22x - 14y = -8   be equation (4)

Subtract equation (4) from equation (3) , we get

-120x = -20

Divide by 120 on both sides , we get

x = 1/6

Now , substituting the value of x in equation (1) , we get

11x - 7y = -4  

11 ( 1/6 ) - 7y = -4

Adding 7y on both sides , we get

7y - 4 = 11/6

Adding 4 on both sides , we get

7y = 11/6 + 4

7y = 35/6

Multiply by 7 on both sides , we get

y = 5/6

Hence , the value of x is 1/6 and value of y is 5/6

Awnser-H=5/2

Explantion- Absolute value equalitiy entered

     7|-3h+8| = 21h-49  Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is 7|-3h+8|

For the Negative case we'll use -7(-3h+8)  

For the Positive case we'll use 7(-3h+8)  

-7(-3h+8) = 21h-49  

    Multiply

     21h-56 = 21h-49  

    Rearrange and Add up

     0h = 7  

    False, No solution for the Negative Case 7(-3h+8) = 21h-49  

    Multiply

     -21h+56 = 21h-49  

    Rearrange and Add up

     -42h = -105  

    Divide both sides by 42

     -h = -(5/2)  

    Multiply both sides by (-1)

     h = (5/2)  

    Which is the solution for the Positive Case When an absolute value equation has just one solution, that solution has to be checked:

The equality is  7|-3h+8| = 21h-49  

The solution is  h = 5/2  

We check the solution by plugging it for h

7|-3(5/2)+8| = 21(5/2)-49  

The left hand side is equal to   (7/2)  

The right hand side is equal to   (7/2)  

The two sides are equal!

Solution checks!

Answer:

C) 6

Step-by-step explanation:

I converted the equation into slope-intercept form and then identified the y-intercept.

[tex]4x+2y=12\\\\4x-4x+2y=12-4x\\\\2y=12-4x\\\\\frac{2y=12-4x}{2}\\\\ y=6-2x\\\\y=-2x+6\\\\y=-2x+\boxed{6}[/tex]

C should be the correct answer.

Hope this helps.

Answer: 6

Step-by-step explanation: The y-intercept is a point where a line

crosses the y-axis and all y-intercepts have an x-coordinate of zero.

So to find the y-intercept of this line, we can plug a 0 in for x.

So we have 4(0) + 2y = 12.

So 2y = 12 which means that y = 6.

So the y-intercept of this line is 6.

Having 1 as an exponent does nothing to the original number.

[tex]f^{-1}[/tex](x) = [tex]\frac{1}{3}[/tex] x + 7

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 3(x - 9) + 6 ← distribute and simplify right side

y = 3x - 27 + 6 = 3x - 21 ( add 21 to both sides )

y + 21 = 3x ( divide all terms by 3 )

[tex]\frac{1}{3}[/tex] y + 7 = x

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

[tex]f^{-1}[/tex](x) = [tex]\frac{1}{3}[/tex] x + 7

1 oz = 0.0625 lb

Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb

                                                                            = 21 : 2

Hiker's weight       Backpack weight                  Total weight (in lb)

1). 152 lb 4 oz                14 lb 8 oz                (152+14) lb (4+8) oz = 164lb 12oz

                                                                                                  = 16.75 lb

2). 107 lb 10 oz               10 lb 4 oz                (107+10) lb (10+4) oz = 117 lb 14 oz

                                                                                                        = 117.875 lb

Answer:

X = 9 and Y = 8

Step-by-step explanation:

We are to find the midpoint of the coordinates  (13,15) and  (5,1).

Using the midpoint formula;

M(X, Y) = [(x1+x2)/2, (y1+y2)/2]

X = (x1+x2)/2

Y = (y1+y2)/2

From the coordinates, x1 = 13, y1 = 15, x2 = 5 and y2 = 1

X = 13+5/2

X = 18/2

X = 9

Similarly;

Y = 15+1/2

Y = 16/2

Y = 8

Hence The Tourist Information Center is located at point X = 9 and Y = 8
