Reflect pentagon A over the y-axis, rotate it 180° clockwise about the origin, and translate it 3 units up.

B.
Rotate pentagon A 90° clockwise about the point (1, 1), reflect it over the x-axis, and translate it 3 units to the left.

C.
Rotate pentagon A 90° clockwise about the origin, reflect it over the x-axis, and translate it 6 units to the left.

D.
Reflect pentagon A over the y-axis and translate it 2 units to the left and 8 units up.

The linear equation for the area is:

40 = 7*(x + 4)

The solution is x = 1.71 = x

Remember that for a rectangle of length L and width W, the area is:

A = L*W

In this case, we can see that:

W = 7

L = x + 4

A = 70

Replacing that, we can get the linear equation:

40 = 7*(x + 4)

Now we can solve this, we jus need to isolate x.

40/7 = x + 4

40/7 - 4 = x

5.71 - 4 = x

1.71 = x

The solution is x = 1.71 = x

The angle of m1, angle of m2 and angle of m3 is 101°, 79° and 101° respectively.

It is given that the angle of m4 is 79°.

To find angles m1, m2 and m3 :

As we know that angle m4 is equal to angle m2 (because they are vertically off opposite angle).

So, angle m2 = 79º

In the same manner the angle of m1will be equal to angle m3.

Now, we can see that in the figure the angles m2 and m1 is lying on one plane, and a plane line makes a angle of 180º

So,

m2+m1 = 180º

79º+m1 = 180º

m1 = 180º-79º

Angle m1 = 101º

And, as we can see that the angles m1 and m3 are vertically of opposite angle.

So, m1= m3= 101º

Hence, angle m1=101º,

            angle m2= 79º,

 And,    angle m3=101º.

The slope of the line in simplest form is: 1.

The slope (m) of a line is calculated as:

Slope (m) = rise/run = change in y / change in x.

The horizontal distance across the line is the run, while the vertical distance is the rise.

The blue line shows the rise of the line = 2 units

The red line shows the run of the line = 2 units

Slope (m) = rise/run = 2 units/2 units

Slope (m) = 1

Therefore, the slope of the line in simplest form is: 1.

Answer:

1 lb corn and 4 lb lima beans

Step-by-step explanation:

Let x = weight of corn.

Let y = weight of lima beans.

x + y = 5

0.6x + 1.1y = 5

x = 5 - y

0.6(5 - y) + 1.1y = 5

3 - 0.6y + 1.1y = 5

0.5y = 2

y = 4

x + y = 5

x + 4 = 5

x = 1

Answer: 1 lb corn and 4 lb lima beans

From the graph of the function, we have that:

Hence:

Looking at the graph, we get that a function f(x) is decreasing when it is "moving northeast", that is, to the right and up on the graph, meaning that when x increases, y decreases.

The amount of milliliters (ml) you should give the child is 1.5 ml

The given parameters are:

infant's Tylenol, 5 ml = 160 mg

This can be represented as

5 ml = 160 mg

Let the number of ml to give a child that requires 48 mg be x

So, we have:

5 ml = 160 mg

x = 48 mg

Cross multiply

x * 160 = 48 * 5 ml

Divide both sides by 160

x = 1.5 ml

Hence, the amount of milliliters (ml) you should give the child is 1.5 ml

The Surface area to be painted = 512 ft²

The surface area of a rectangular prism = 2(w × l + h× l + h × w). Where:

w = width of the rectangular prism

h = height of the rectangular prism

l = length of the rectangular prism

The block column has a shape of rectangular prism. Therefore, the surface area that Richard needs to paint which excludes the bottom of the block = 2(w × l + h× l + h × w) - l × w.

Plug in the values

Surface area to be painted = 2(8 × 10 + 12 × 10 + 12 × 8) - 10 × 8

The measurement of the actual angle NOP is 56° when it is being dilated by the scale factor of 2 to form the dilated angle NOP as 112° .

We are given the dilated angle as:

∠ NOP = 112°

The scale factor for dilation is given as 2.

Now, we need to find the value of actual angle NOP.

For this, we will divide the dilated angle NOP with the scale factor of dilation.

So, we will get the result as:

Actual ∠ NOP = 112° / 2

Actual ∠ NOP = 56°

Step-by-step explanation:

The length of the circle's radius = 744.92 cm

Given the length of arc of a circle, arc length = 269⁢π cm

Central angle of a circle is the angle made between the radius through the arc length at the center of the circle.

The corresponding central angle = 65°

To find the corresponding central angle in radians = 65° x π/180 = 13π/36 radians

We have, arc length of a circle = radius x central angle

Therefore, radius of the circle = arc length / central angle

                                                  =  269⁢π /(13π/36)

Step-by-step explanation:

[tex]\displaystyle\\y=\frac{1}{4} (x+2)^2-6\\y > 0\\Hence,\\\frac{1}{4}(x+2)^2-6 > 0 \\\\\frac{1}{4}(x+2)^2-6+6 > 0+6\\\\\frac{1}{4}(x+2)^2 > 6\\[/tex]

Multiply both parts of the equation by 4:

[tex](x+2)^2 > 24[/tex]

Extract the square root of both parts of the inequality:

[tex]|x+2| > \sqrt{24} \\|x+2| > \sqrt{4*6} \\|x+2| > 2\sqrt{6}[/tex]

Expand the modulus - we get a set of inequalities:

[tex]\displaystyle\\\left [{{x+2 > 2\sqrt{6}\ \ \ \ (1) } \atop {-(x+2) > 2\sqrt{6} \ \ \ (2)}} \right.\\[/tex]

Multiply both parts of inequality (2) by -1 and reverse the sign of the inequality:

[tex]\displaystyle\\\left [ {{x+2-2 > 2\sqrt{6}-2 } \atop {x+2 < -2\sqrt{6} }} \right. \ \ \ \ \ \left [ {{x > 2\sqrt{6}-2 } \atop {x+2-2 < -2\sqrt{6} -2}} \right. \ \ \ \ \ \left [ {{x > 2\sqrt{6}-2 } \atop {x < -2\sqrt{6}-2 }} \right.[/tex]
