Hello can someone please help me with this

Answer:

E

Step-by-step explanation:

Let

A = # of slices Alice got

B = # of slices Bob got

C = # of slices Charles got

D = # of slices Darwin got

First, write equations based on given information:

A = 0

B = 2C

5C = D

D = C + 8

5C = D -> D = 5C

Now that we have two equations for D, we can set them equal to each other:

5C = C + 8

4C = 8

C = 2

Now just plug in the rest:

A = 0

B = 2(2) = 4

C = 2

D = 2 + 8 = 10

Add all solutions together to get (E) 16 slices

The easiest way to find the slope of a line is converting the line equation into the slope-intercept form.

There are 3 forms of line equations:

- slope intercept form, the equation is given by:

 y = mx + b

Where:

m = slope

- point slope form, the equation is given by:

y − y₁ = m (x - x₁)

Where:

m = slope

- standard form: Ax + By = C

The easiest way to find the slope of a line is to convert it into a slope-intercept form.

Example:

Line equation in standard form:

2x + 4y = 6

We will convert it into  slope-intercept form.

4y = -2x + 6

y = (-2/4) x + 6

y =  (-1/2) x + 6

Hence, the slope is  (-1/2)

Answer:

he arrived at school at 7:18

Step-by-step explanation:

Time = distance/speed  = 3mi/30mph

= 3/30

= 0.1 hour

= 6 minutes

= 00:06:00

To find the endpoint we have to calculate the distance between the known midpoint to the known endpoint. To calculate the midpoint we add two points and divide them by 2.

The formula for midpoint = (x1 + x2)/2, (y1 + y2)/2.

Substituting in the two x-coordinates and two y-coordinates from the endpoints.

Putting it together,

The endpoint formula is:

(x a ,ya)= ((2xm−xb),(2ym−yb))

( x a , y a ) = ( ( 2 x m − x b ) , ( 2 y m − y b ) ).

The end of a line at a point that is equally distant from both ends, a time interval between an event's beginning and end.

The point on a graph or figure where the figure stops might be referred to as the endpoint. It can be the point joining the sides of a polygon (the vertex), the common endpoint of two rays making an angle, the two extreme points of a line segment, the one end of a ray.

Step-by-step explanation:

First, find the slope from the first 2 points, then use the value of the slope and either one of the first 2 points to find y in the 3rd point.

m = (8 - 4)/(3 - 1) = 4/2 = 2

2 = (y - 4)/(6 - 1)

By solving, we see that the product of the polynomials 4 - a and a3 + 7a - 18 is a3 + 3a2 + 46a + 72.

The location on the y-axis where the slope of the line passes is known as the intersection point in mathematics. a point on a line or curve where the y-axis crosses. The equation for the straight line is given as Y = mx+c, where m denotes the slope and c the y-intercept. In the intercept form of the equation, the line's slope (m) and y-intercept (b) are highlighted. The slope and y-intercept of an equation with the intercept form (y=mx+b) are m and b, respectively. There are several equations that can be rewritten to look like slope intercepts. The slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0, for example.

given

(4 - a) * ( a3 + 7a - 18 )

= 4a3 + 28a - 72 - a4 + 7a2 + 18 a

= a3 + 3a2 + 46a + 72

By solving, we see that the product of the polynomials 4 - a and a3 + 7a - 18 is a3 + 3a2 + 46a + 72.

A natural number other than 1 whose only factors are 1 and itself is said to be a prime factor. In actuality, the first few prime numbers are 2, 3, 5, 7, 11, and so forth. The lowest of two or more natural numbers' common multiples is referred to as the Lowest Common Multiple (LCM). A prime factor is a natural integer, other than 1, whose sole factors are itself and 1. Actually, 2, 3, 5, 7, 11, and so forth are the first few prime numbers. The term "Lowest Common Multiple" refers to the common multiple of two or more natural integers that is the lowest (LCM).

The prime factors of 24 are: 2,2,2 and 3.

The prime factors of 84 are: 2,2,3 and 7.

Now, The Lowest Common Multiple (LCM) of 24 and 84 is calculated using the prime factors of both the numbers.

LCM= 2*2*2*3*7= 168

Hence, The Lowest Common Multiple of 24 and 84 is 168.

Marla is 30 years old.

Let marla age be x and Darla age be y

Given : Marla is four years less than twice as old as Darla

What is equation ?

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Marla is four years less than twice as old as Darla can be represented as : 2y - x = 4

sum of their ages is 47 can be represented as : x + y = 47

Solving both the equation using addition we got ,

3y = 51

y = 17

Substituting the value of y in x + y =47 , we get

x + 17 = 47

x = 47 -17

x = 30

Hence , Marla is 30 years old.

So the expression evaluates to 14 when x = 2.

To evaluate the expression, we first substitute x = 2 into the expression:

5(2 - 6 + 3*2)^2 - 6

There are two methods for solving simultaneous linear equations: graphical methods and algebraic methods. The algebraic technique includes the substitution method as one of its categories.

The value of one variable from one equation is substituted in the second equation using the substitution method. In this manner, a pair of linear equations is reduced into a single linear equation with only one variable, which can then be solved quickly.

Next, we simplify the expression inside the parentheses:

=5(2 - 6 + 6)^2 - 6

=5(2)^2 - 6

=5*4 - 6

=20 - 6

=14

So the expression evaluates to 14 when x = 2.

Answer:

I believe the answer is 45.

Step-by-step explanation:

a 90 degree angle is represented by a square on the corner.

So half of 90 is:

90 ÷ 2 = 45

the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.

45 + 90 = 135

and 180 - 135 = 45

(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.

So, the length of JL is equal to 45 degrees.

Answer:

Step-by-step explanation:

We need to transform the given x^2 - 19x + c into the form

                                                      (x - a)^2 + d

by completing the square:

1.  Take half of the coefficient (-19) of x, obtaining -19/2.

2.  Square this result, obtaining 361/4.

3.  Add this to x^2 - 19x, and then immediately subtract it:

    x^2 - 19x + c becomes x^2 - 19x + 361/4 - 361/4+ c

4.  Replace the first three terms with (x - 19/2)^2:

     x^2 - 19x + 361/4 - 361/4+ c  =>  (x - 19/2)^2 - 361/4 + c

5.  Put this into final form: (x - 19/2)^2 - (361/4 - c)
