-18n+20n^2

Answer:

∠ ABD = 124°

Step-by-step explanation:

A linear pair of angles sum to 180°, thus

∠ ABD + ∠ CBD = 180 , substitute values

3x + 31 + 2x - 6 = 180, that is

5x + 25 = 180 ( subtract 25 from both sides )

5x = 155 ( divide both sides by 5 )

x = 31

Thus

∠ ABD = 3x + 31 = 3(31) + 31 = 93 + 31 = 124°

Adding -5 is like subtracting 5

3 -5

-2

Answer:

-2

Step-by-step explanation:

You need to add a positive number and a negative number.

This is how you add a positive number and a negative number.

First, get rid of the signs and make them both positive.

Now you have 5 and 3.

Do a subtraction the way you first learned subtraction in elementary school, which is the larger number minus the smaller number.

5 - 3 = 2

The answer is either 2 or -2.

To finish the original addition, look at the two original numbers. 5 is greater than 3. 5, the greater value, is on a negative number, so the answer is negative.

3 + (-5) = -2

Answer:

irrational are all square roots. rattional numbers are the decimals. If it has a pie, that means that is also irrational. So decimal are rational numbers. Square roots are all irrational number.

Answer:

y = -5x + 7

Step-by-step explanation:

Given that the location of the points are:

A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1)

The location of the bisector of a line is given as:

[tex]x=\frac{x_1+x_2}{2} \\\\y=\frac{y_1+y_2}{2}[/tex]

If E(x1, y1) is the bisector of segment AB then the location of E is at:

[tex]x_1 =\frac{-4+6}{2}=1 \\\\y_1=\frac{1+3}{2}=2[/tex]

Hence E is at (1, 2)

If F(x2, y2) is the bisector of segment CD then the location of F is at:

[tex]x_2 =\frac{-1+5}{2}=2 \\\\y_2=\frac{-5-1}{2}=-3[/tex]

Hence F is at (2, -3)

Hence the line that is a segment bisector of both AB and CD pass through the point (1, 2) and (2, -3).

The equation of the line is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-2=\frac{-3-2}{2-1}(x-1)\\ \\y-2=-5(x-1)\\\\y-2=-5x+5\\\\y=-5x+7[/tex]

Answer: The equation is: y = -5x + 7.

Step-by-step explanation:

Given that the location of the points are:

A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1).

Midpoint of A(-4, 1), B(6, 3) is = [tex]\left(\frac{\left(-4+6\right)}{2},\frac{\left(1+3\right)}{2}\right)=(1,2)[/tex].

Midpoint of C(-1, -5) and D(5, -1) is [tex]\left(\frac{\left(-1+5\right)}{2},\frac{\left(-5-1\right)}{2}\right)=(2,-3)[/tex].

Using point slope formula:

[tex]\frac{y-2}{x-1}=\frac{-3-2}{2-1}\\\frac{y-2}{x-1}=-5\\y-2=-5x+5\\y=-5x+7[/tex]

The domain refers to values on the X-axis, and as you can see there are arrows on the orange line, meaning it goes on "forever". This is all real numbers.

The y-axis (range) has the line go through at -2. The line is pointing up, which means all the numbers are greater than -2, or could be equal to -2.

Answer:

36

Step-by-step explanation:

First of all, the area of a circle is always pi(r)^2, which we can then substitute values. We will get pi(10)^2, and once we simplify that, we get 100pi as the area. Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.

Answer: 4x^3-38x^2+88x

Step-by-step explanation:

The volume of the box in standard form is 4x³ - 38x² + 88x

Since Janelle cuts a square of side length x out of each corner of the cardstock, we have a length x + x = 2x cut out of each dimension of the cardstock.

Since the dimensions of the cardstock are 8 inches by 11 inches, cutting out a length of 2x inches from each dimension to produce the length, L and width, w of the open box, we have the length of the open box, L = 8 -2x and the width of the open box, W = 11 - 2x.

Since the height of the open box is the length x of the square cut out of each corner, and the open box is a rectangular box,

So, the volume of the box is

V = LWx

Substituting the values of the variables into the equation, we have

V = LWx

V = (8 - 2x)(11 - 2x)x

Expanding the brackets, we have

V = (88 - 16x - 22x + 4x²)x

V = (88 - 38x + 4x²)x

V = 88x - 38x² + 4x³

Re-arranging, we have

V = 4x³ - 38x² + 88x

So, the volume of the box in standard form is 4x³ - 38x² + 88x

Step-by-step explanation:

Since the line segment FH bisects angle EFG, angle HFG = Half of Angle EFG.

Angle EFG = 177 - 9x. Angle HFG = 92 - 8x.

177 - 9x = 2(92 - 8x)

177 - 9x = 184 - 16x

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that y = 2x and 3x – 3y = 2, therefore, if we substitute the value of y from y=2x into the second equation 3x-3y=2, then,

3x – 3y = 2

3x – 3(2x) = 2

3x – 6x = 2

–3x = 2

x = 2/–3

Hence, the value of x in the two of the given equations is 2/–3.
