How to divide 83 by 4

The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

x + y = -3      subtract x from both sides

y = -x - 3

When raising a monomial to a power, you multiply the exponents of each variable by that power.

When you raise a monomial to the power of 2, you multiply the exponents of each variable by 2. So in the given monomial ax6y12, you would raise each exponent to the power of 2 to get a2x12y24.

Similarly, when you raise a monomial to the power of 3, you multiply the exponents of each variable by 3. So in the given monomial ax6y12, you would raise each exponent to the power of 3 to get a3x18y36.

Answer:

y = √7

Step-by-step explanation:

This circle has a center at (0,0) and a radius of 4 so its equation is:-

x^2 + y^2 = 16

when x= -3, (-3)^2 + y^2 = 16

9 + y^2 = 16

y^2 = 7

y = √7

Answer:

80°

Step-by-step explanation:

Three angles are equal

Let the equal angle be x

3x+120=360

3x=240

x=240/3

=80

Hence the three angles are 80∘

Answer:

Each of the three congruent angles has measure 80 deg. The fourth angle has measure 120 deg.

Step-by-step explanation:

The sum of the measures of the angles of an n-sided polygon is (n - 2)180.

A quadrilateral has 4 sides, so n = 4 in the formula above.

(n - 2)180 = (4 - 2)180 = 2(180) = 360

The sum of the measures of the angles of a quadrilateral is 360 degrees.

Three angles are congruent. Let the measures of the three congruent angles be x. The sum of the measures of the 3 angles is x + x + x = 3x.

The sum of the measures of the angles is 360 deg.

3x + 120 = 360

Subtract 120 from both sides.

3x = 240

Divide both sides by 3.

x = 80

Answer: Each of the three congruent angles has measure 80 deg. The fourth angle has measure 120 deg.

The value of x is the point of intersection of the graphs of [tex]\mathbf{P =12 + 2x}[/tex] and [tex]\mathbf{A =6x}[/tex]

The value of x is 3

The given parameters are:

The reflexive property justifies the statement "If CD = EF, then CD = EF".

The reason that justifies the statement "If CD = EF, then CD = EF" is the reflexive property.

The reflexive property states that any geometric shape or object is always equal to itself. In this case, CD is equal to itself, and EF is equal to itself, so if CD = EF, then CD will always be equal to EF.

Therefore, option B, the reflexive property, is the correct reason for the given statement.

Step-by-step explanation:

To find the answer, we can use the method of exterior angle of triangles, which would be <A + <B = <C, in which A and B is any interior angles of triangles and C would be the exterior angle for the remaining angle.

In this case:

45°+60° = 105°

Therefore the answer is C. 105°

Answer:

The square has 4-fold reflectional symmetry. The regular octagon has 8-fold symmetry.

Step-by-step explanation:

For a square,

There are two lines of symmetry along two diagonals and

two lines of symmetry along midpoints of two pairs of opposite sides.

Therefore, there are 4 lines of reflectional symmetry in total.

For a regular octagon,

There are four lines of symmetry along four diagonals and

four lines of symmetry along midpoints of four pairs of opposite sides.

Therefore, there are 8 lines of reflectional symmetry in total.

Final answer:

A square has 4-fold reflectional symmetry, while a regular octagon has 8-fold reflectional symmetry.

Explanation:

Reflectional symmetry refers to a property of a shape where it can be divided into two mirror-image halves. The -fold reflectional symmetry of a regular polygon refers to the number of lines of symmetry it possesses. A line of symmetry is an imaginary line that divides the shape into two equal halves that are mirror images of each other.

For example, a square has 4-fold reflectional symmetry because it has 4 lines of symmetry, dividing it into 4 equal halves. Each line of symmetry passes through the midpoints of opposite sides.

On the other hand, a regular octagon has 8-fold reflectional symmetry because it has 8 lines of symmetry, dividing it into 8 equal halves. Each line of symmetry passes through the midpoints of opposite sides or vertices.

Step-by-step explanation:

Answer:

According to the question,

Numbers are : 23 and -6

The two numbers are -6 and 23.

To find the two numbers, we can set up a system of equations based on the given information. Let the two numbers be [tex]\( x \) and \( y \), where \( x > y \)[/tex]. According to the problem, we have:

1. The sum of the two numbers is 17:

[tex]\[ x + y = 17 \][/tex]

2. The difference between the two numbers is 29:

[tex]\[ x - y = 29 \][/tex]

Now, we can solve this system of equations. We can add the two equations together to eliminate [tex]\( y \)[/tex] :

[tex]\[ (x + y) + (x - y) = 17 + 29 \] \[ 2x = 46 \] \[ x = \frac{46}{2} \] \[ x = 23 \][/tex]

Now that we have the value of [tex]\( x \)[/tex], we can substitute it back into one of the original equations to find [tex]\( y \)[/tex]. Let's use the first equation:

[tex]\[ 23 + y = 17 \] \[ y = 17 - 23 \] \[ y = -6 \][/tex]

Therefore, the two numbers are 23 and -6.

Answer:

[tex]y=\frac{3}{2} x+6[/tex]

Step-by-step explanation:

We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:

[tex]\frac{2}{3} y-4=x[/tex]

Taking the constant 4 to the side where x is to get:

[tex]\frac{2}{3} y=x+4[/tex]

Multiplying the denominator 3 to the other side of the equation to get:

[tex]2y=3x+12[/tex]

Isolating y to make it the subject:

[tex]y=\frac{3}{2} x+\frac{12}{2}\\ \\y=\frac{3}{2} x+6[/tex]

The formula of a volume of a cuboid:

[tex]V=lwh[/tex]

l - length

w - width

h - height

h = 3 cm

Substitute:

[tex]V=(x+4)(x+1)(3)[/tex]      use distributive property

[tex]V=(x+4)(3x+3)[/tex]

[tex]V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)[/tex]

[tex]V=3x^2+3x+12x+12[/tex]      combine like terms

Answer:

   The legs are congruent by definition.

   The lower base angles are congruent.

   The upper base angles are congruent.

   Any lower base angle is supplementary to any upper base angle.

   The diagonals are congruent.

Step-by-step explanation:

Answer:

(a)

Given: A line passes through the points (3, -2) and (6, 2)

Point slope form: An equation of line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:

[tex]y -y_1=m(x-x_1`)[/tex]  .....[1] where m is the slope of the line.

Calculate first the slope of the line:

Slope(m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the given points;

[tex]m = \frac{2-(-2)}{6-3}=\frac{2+2}{3} =\frac{4}{3}[/tex]

Substitute the value of m in [1] ;

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

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

therefore, the equation of line in point slope form is, [tex]y+2=\frac{4}{3}(x-3)[/tex]    

(b)

to find the standard form of the equation [1]

Multiply both sides by 3  in [1] we get;

[tex]3(y+2) = 4(x-3)[/tex]

using distributive property;   [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]

3y + 6 = 4x -12

Subtract 3y to both sides we get;  

3y + 6 -3y = 4x - 12 - 3y

Simplify:

6 = 4x - 3y -12

Subtract 6 from both sides we get;

0 = 4x - 3y -12-6

Simplify:

4x - 3y - 18 =0

Therefore, the standard form of the equation is; 4x - 3y - 18 =0
