Answer:

y= 1/14 x +17/14

Step-by-step explanation:

Lines perpendicular to another line have an opposite reciprocal slope, meaning that the sign is changed, and the fraction is flipped. We are going to use point-slope form to solve.

[tex]y-y_{1} =m(x-x_{1} )\\y-1 =\frac{1}{14} (x+3 )\\y-1=\frac{1}{14}x+\frac{3}{14}\\y=\frac{1}{14}x+\frac{17}{14}[/tex]

Step-by-step explanation:

The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.

let the total fund funds be y

and the number of weeks be w

For John's fund the expression is

y=45w+1814------1

Marco's College Fund

y=25 w+1744---------2

equating 1 and 2 we have

45w+1814=25w+1744

45w-25w=1744-1814

20w=-70

divide both sides by 20 we have

w=-70/20

w=-3.5

this means that in 3 and half weeks the two funds will have the same amount in them

Answer:

[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

(2,1) (8,9)

The formula that you would use is:

[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]

So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]

and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]

When we insert these numbers into the equation, we get:

[tex]\frac{9-1}{8-2}[/tex]

When we solve that we get:

[tex]\frac{8}{6}[/tex]

Now we simplify it by dividing both the numerator and denominator by 2, which would give us:

[tex]\frac{4}{3}[/tex]

Hiroaki is mistaken since the line should pass through the origin, negating the possibility of the proportionality constant being a simple whole number.

Whole numbers are defined as natural numbers plus zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, 4, and so forth. Whole numbers are a collection of numbers that don't contain any fractions, decimals, or even negative integers. It is made up of zero and positive integers. Alternately, we may define whole numbers as the collection of non-negative integers. The inclusion of zero in the set of whole numbers marks the main distinction between them and natural numbers.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.

Step-by-step explanation:

The ratio is simply the fractional representation of two values in their simplest form. The ratio of Cell A to Cell B is 20 which means that the size of Cell A is 20 times the size of Cell B.

Given that :

Cell size A = [tex]Cell A = 0.0005\times 10^{-5}\\\\Cell B = 0.0025\times10^{-7} \\\\Ratio = \frac{Cell A }{Cell B} \\\\Ratio = \frac{0.0005 \times 10^-5}{0.0025 \times 10^-7}[/tex]

[tex]Ratio = 20[/tex]

Therefore, the ratio of the size of Cell A to the size of Cell B is 20 : 1, which can be interpreted to mean that cell A is 20 times larger than cell B.

[tex]x=\frac{576}{11}[/tex]

Step-by-step explanation:

13x - 12x + 45 * 12 = 14 - 12x - 10.5

Multiply first

13x - 12x + 540 = 14 - 12x - 50

Combine like terms

x + 540 = 12x - 36

Subtract x from both sides

540 = 11x - 36

Add -36 to both sides

576 = 11x

Divide both sides by 11

[tex]x=\frac{576}{11}[/tex]

The number of cups of sugar will be 11²/₃.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Donna's recipe calls for 2¹/₃ cups of sugar for each cake. Donna wants to make 5 cakes.

The number of cups of sugar will be,

Number = 2¹/₃ x 5

Number = (7/3) x 5

Number = 35 / 3

Number = 11²/₃.

Answer:

independent: number of tickets purchased;

dependent: total cost;

rule: f(x) = 60x

Step-by-step explanation:

The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.

The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.

The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.
