The point (1, 9) with a slope of 4 on a graph corresponds to the answer of 13.

The answer is 13.

To calculate this, we use the formula for the equation of a straight line: y = mx + b, where m is the slope and b is the y-intercept. In this case, the equation would be y = 4x + 9. Substituting x = 1 into the equation gives y = 4(1) + 9 = 13.

Therefore, the point (1, 9) has a slope of 4 on the graph.

hyp = 3[tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex] = 3 × 2 = 6

Answer:

The correct option is third one m∠2 =106° , m∠3 =37°.

Therefore,

[tex]m\angle 2 = 106\°\\m\angle 3 = 37\°[/tex]

Step-by-step explanation:

Given:

Consider ABCD as a Rhombus such that,

∠A = ∠1 = 106°

∠C = ∠2

∠BDC = ∠3

AB=BC=CD=DA

To Find:

∠2 = ?

∠3 = ?

Solution:

ABCD is a Rhombus

∠A ≅ ∠C  ............opposite angles of Rhombus are equal. ( property )

Substituting the values we get

∠1 = ∠2

But ∠1 = 106°

∴ ∠2 = 106°    ....... Transitive property,

As BC = CD   ...Given

ΔBCD is an Isosceles triangle

∴ ∠CBD ≅ ∠BDC = ∠3  ........base angle of Isosceles triangle are congruent.

we know that in a triangle,

Sum of measures of all angles is 180°

in Triangle BCD

[tex]\angle 3 +\angle 2 +\angle 3 =180[/tex]

Substituting the values we get

[tex]2m\angle 3 =180-106=74\\\\\angle 3=\dfrac{74}{2}=37\\\\m\angle 3 = 37\°[/tex]

Therefore,

[tex]m\angle 2 = 106\°\\m\angle 3 = 37\°[/tex]

The graph which shows the pre-image of quadrilateral ABCD and the image A’ B’ C’ D’ after the rotation is graph number 1.

Rotation of a figure is the transformation of it about a point in either clockwise or anticlockwise direction.By rotating, a figure changes the point of the figure.

The quadrilateral ABCD and point E in the graphed in the figure below. This quadrilteral is rotated r(135°, E) in order to construct quadrilteral A’ B’ C’ D’ .

The rotation of the figure is 135 degrees. This angle can be break as,

[tex]\theta=135\\\theta=90+45[/tex]

The angle is rotated 90 and 45 degrees. To rotate 90 degree, the angle must be flliped 90 degree clockwise from point E keeping the point c at center.

After this the 45 degree more the figure is rotated. This is shown accurately in the figure A.

Thus, the graph which shows the pre-image of quadrilateral ABCD and the image A’ B’ C’ D’ after the rotation is graph number 1.

Answer:

The dimensions of the rectangle are;

Width = 3 inches

Length = 9 inches

Step-by-step explanation:

Given;

We want to determine the dimensions of the rectangle;

Forming an equation, we get;

2 ( x + x + 6) = 24

4x + 12 = 24

With the equation we can solve for x

4x = 24 - 12

4x = 12

  x = 3

and (x + 6) = 9

Therefore;

Width = 3 inches

Length = 9 inches

The width of the rectangle is 3 inches and the length is 9 inches.

Let's assume that the width of the Rectangle dimensions is represented by 'w' inches.

Since the length is 6 inches more than the width, we can represent it as 'w + 6' inches.

The perimeter of a rectangle is the sum of all its sides.

In this case, the formula for the perimeter is 2(w + l), where w represents the width and l represents the length.

So, for this problem, we have the equation 2(w + w + 6) = 24.

Simplifying this equation, we get 4w + 12 = 24.

Solving for 'w', we find that the width is 3 inches.

Plugging this value back into the equation for the length, we find that the length is 9 inches.

The area of the figure is 40 units. (rounded off from 39.998 units)

Step-by-step explanation:

1. Area of the figure = Area of Rectangle + Area of Parallelogram.

2. Naming points:

Let the rectangle consist of points A(-6,-1), B(-5,-5), C(3,-3) and D(2,1).

Let the parallelogram consist of points C(3,-3), D(2,1), E(2,7) and F(3,3).

3. Each coordinate has a point on the x-axis and a point on the y-axis. We shall refer to these points as x', x'' ,x''' and so on corresponding to the x-axis values of A, B, C and so on in that order till F. For the y-axis points, we will name them in the series of y', y'', y''' and so on.

In simple words, in A(-6,1), x' = -6; y' = -1

4. Formula for finding area:

Area of a rectangle = length (l) × width (w)

Area of a parallelogram = base (b) x height (h)

5. Finding area of the rectangle:

l = AD = [tex]\sqrt{[x'''' - x']^{2} - [y'''' - y']^{2}}[/tex]

, i.e. AD = [tex]\sqrt{[2 - (-6)]^{2} - [1 - (-1)]^{2}}[/tex]

, i.e. AD = √68 = 8.246 (rounded to 3 decimals) = l

Now, w = AB = [tex]\sqrt{[x'' - x']^{2} - [y'' - y']^{2}}[/tex]

, i.e. AB = [tex]\sqrt{[(-5) - (-6)]^{2} - [(-5) - (-1)]^{2}}[/tex]

, i.e. AB = √17 = 4.123 (rounded to 3 decimals) = w

Area of rectangle = l x w = 8.246 x 4.123 = 33.998 units.

6. Finding area of the parallelogram:

b = DE = 6 units (we can observe this from the graph, i.e. points from 1 to 7 on the y axis)

h = Height is the line drawn perpendicular to the base from point F, which as we can see is 1 unit long.

Hence, Area of parallelogram = b x h = 6 x 1 = 6 units.

7. Now, adding both, we can arrive at the final answer.

Area of the figure = Area of rectangle + Area of parallelogram,

i.e. 33.998 units + 6 units = 39.998 units. (can be rounded off to 40 units)

Answer:

The actual weight is 1.1% less (100 - 98.9) than the labeled weight.

Step-by-step explanation:

1. Let's review the information given to us to answer the question properly:

Labeled weight of the bag of chocolates = 0.384 pounds

Actual weight of the bag of chocolates = 0.3798 pounds

2.  How much have you or lighter are the chocolates and the stated on the label. Show your reasoning.

Let's find how much we have comparing the labeled weight and the actual weight, using a Direct Rule of Three, this way:

Weight               Percentage

0.384                    100 %

0.3798                      x %

0.384x = 0.3798 * 100

0.384x = 37.98

x = 37.98/0.384

x = 98.9 (Rounding to one decimal place)

The actual weight is 1.1% less (100 - 98.9) than the labeled weight.

The chocolates are 0.0042 pounds lighter than what is stated on the label.

The difference in weight between the labeled weight and the actual weight of the chocolates is 0.0042 pounds. This means that the chocolates are 0.0042 pounds lighter than the label indicates.

To calculate this, subtract the actual weight from the labeled weight: 0.384 - 0.3798 = 0.0042 pounds.

So, the chocolates are 0.0042 pounds lighter than what is stated on the label.

The inequality that represents the graph is  y < [tex]\frac{1}{4}[/tex]x + 2

Step-by-step explanation:

i) the region below a dashed line through the points (4,3) and (0,2) is shaded.

ii) first we find the equation of the line passing through the points (4,3) and (0,2)

(y - 3) = [tex](\frac{3 - 2}{4 - 0})[/tex](x - 4)    ⇒    y - 3 =  [tex]\frac{1}{4}[/tex](x - 4)  

⇒  4y - 12 = x - 4       ⇒     4y = x + 8      ⇒     y = [tex]\frac{1}{4}[/tex]x + 2

iii) for the area shaded below the line whose equation is given in ii) above the inequality that will represent the shaded region is given by

 y < [tex]\frac{1}{4}[/tex]x + 2

The graph represents the inequality y < 1/4x + 2. The inequality was calculated based on the information given: points the line goes through, shading below the line, and the line being dashed all determine the inequality's form.

To determine the inequality graphed, we first need to find the equation of the line. The line passes through the points (4, 3) and (0, 2), so we can use these points to find the slope of the line.

The formula for the slope (m) is [tex](y2 - y1)/(x2 - x1).[/tex]. Plug in the coordinates of the two points into this formula: ([tex]3 - 2) / (4 - 0) = 1/4[/tex] So, our slope is 1/4.

Given a slope (m) of 1/4 and the y-intercept (b) of 2, we can write the equation of the line in slope-intercept form (y = mx + b) as y = 1/4x + 2.

One key part of your question is that the region below this line is shaded. In the language of inequalities, shading below the line corresponds to 'y is less than' the line's equation. Also, the line is dashed, meaning that the points on the line are not included in the solution, which we denote as 'less than' rather than 'less than or equal to'.

So, the inequality represented by this graph is y < 1/4x + 2.
