Area = w × h

w = width

h = height

The proportional equation that represents the situation is:

y = 13x

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality, also called slope.

In this problem, the points (number, cost) are: (3,39), (5,65) and (8,104), hence the slope is given by:

[tex]k = \frac{39}{3} = \frac{65}{5} = \frac{104}{8} = 13[/tex]

Hence, the equation is:

y = 13x.

The slope of the linear equation is $13 per necklace.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope (rate of change), and b is the y intercept (initial value of y).

Let y represent the total charge for x number of necklaces.

From the table, using (3, 39) and (8, 104), hence:

m = (104 - 39) / (8 - 3) = 13

The slope of the linear equation is $13 per necklace.

Answer:

n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.

Step-by-step explanation:

Answer:

Natural numbers are simply positive integers.  For now, refer to the middle number (the third number), as x.  Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2.  Simply add all these numbers to get 5x, a number that is divisible by 5.  As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.

∛-12

The nearest cube  to -12 is -8    ( -27 is the next after -12)

a) The answer is -2.

b) we can do this by trial and improvement

It must be between -2 and -3, closer to -2 than 3 so first we guess -2.1

(-2.1)^3 = -9.261

(-2.2)^3 = -10.648

(-2.3)^3 = `2.167  - very close

Answer is -2.3 .

Step-by-step explanation:

The expression can be written as [tex]8 * 2^7[/tex]

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Example: The standard form of the polynomial 5 + 2x + x² is expressed.

We shall first determine the polynomial's degree before expressing it in standard form.

The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.

Given:

8*2^7

The above expression can be written as

[tex]=8 * 2^7[/tex]

= 8 x 128

= 1024.

Hence, the expression can be written as [tex]8 * 2^7[/tex]

Answer:

The equation of a line in point-slope form is y-Y1=m(x-X1). ”m” is the slope and (X1,Y1) is a point.

So, the equation in point-slope form is y+5=12(x+4).

Answer: 6x^2+1

(very sorry if this is wrong lol)

Step-by-step explanation:

Substitute all the given numbers into the equation, by doing so this should give you 2x-1+3x+2+x^2.

Since we have a group of x’s add them together, which would make 6x^2, this leaves our -1 and +2 add these these two numbers together to make plus one and finally you will have 6x^2+1

Figure RST is congruent is R´S´T´

Step-by-step explanation:

Given that R´S´T is a reflection of RST, we know that is a rigid transformation, so it is congruent (the same size & shape).

Step 1: Simplify both sides of the equation.

3+3y=1−13y−9

3+3y=1+−13y+−9

3y+3=(−13y)+(1+−9)(Combine Like Terms)

3y+3=−13y+−8

3y+3=−13y−8

Step 2: Add 13y to both sides.

3y+3+13y=−13y−8+13y

16y+3=−8

Step 3: Subtract 3 from both sides.

16y+3−3=−8−3

16y=−11

Step 4: Divide both sides by 16.

16y

16=−11/16

y=−11/16

Answer:

y=−11/16
