ATTACHED IS THE SOLUTION

An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0

Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.

There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.

We will find the slope using the slope formula that is

⇒ m  = (y₂ - y₁)/(x₂ - x₁)

Given points are (-5, 3) and (2, 1), so

⇒ m  = (1 - 3)/(2 - (-5))        

⇒ m  = -2/7

We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).​

for a two lines to be parallel, m = m for both lines

so as the slope is (-2/7), lets put the value in (0,0)

y = mx + b

0 = (-2/7)0 + b

b = 0

And therefore the equation is 0 = (-2/7)0 + 0

Answer:

308 Calories are provided by the Powerbar.

Step-by-step explanation:

Use the typical amounts shown for each nutrient first to calculate how many calories each one provides:

Fat: 4 grams x 9 kcal/gram = 36 kcals.

Protein: 23 grams x 4 kcal/gram = 92 kcals.

45 grams x 4 kcal/gram of carbohydrates equals 180 kcal.

To determine the total calories, add up all the Calories from each nutrient as follows:

92 calories from protein and 36 calories from fat equal 308 calories.

The Powerbar contains 308 calories.

Answer:

Total Calories = (4*9) + (23*4) + (45*4)

                           36+92+180 = 308 Calories

To calculate total calories we first need to convert total fat, protein, and carbohydrates into calories

1 gram of protein = 4 calories

1 gram of fat = 9 calories

1 gram of carbohydrates = 4 calories

50 pound in yen is 7200 yen

Algebra is a branch of mathematics that helps translate real-world situations or problems into mathematical truths. Mathematical operations like addition, subtraction, multiplication, and division are needed in addition to variables like x, y, and z to construct a meaningful mathematical expression. All branches of mathematics, such as calculus, trigonometry, and coordinate geometry, employ algebra. A fundamental algebraic equation is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations such as addition, subtraction, multiplication, division, etc. are done on variables and constants. Let's imagine that while playing with matchsticks, James and Natalie came up with the idea to arrange the sticks into designs that represented numbers.

Given that : 1 euro is 120 yen and 1 pound is 1.2 euro

1 euro = 120 yen

1 pound = 1.2 euro

1 pound = 1.2 × 120 yen

1 pound = 144 yen

50 pound = 144 ×50

= 7200 yen

50 pound in yen is 7200 yen

The measure of angle 3 is 45°.

What is an angle?

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing them. Angles are also generated when two planes meet. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction.

Angle 6 = 45° (vertically opposite angles)

The given linear equation has solutions 1000 and 2000. This are values for which the equation is true.

Linear equations are equations that has a leading degree of 1. Given the equation below, we are to determine the value of x from the expression.

Given the linear equation

x/50=20=40

This can be splitted into x/50=20 and x/50 = 40

Solve both equations

x/50=20

Cross multiply

x = 50 * 20

x = 1000

Similarly;

x/50 = 40

Cross multiply

x = 50 * 40

x = 2000

Therefore the solutions to the given system of linear equation are 1000 and 2000

The number of cans each guest must bring to reach the goal must be greater than or equal to 5 by inequality.

What is inequality in math?

Let

x -----> the number of cans each guest must bring to meet the goal

we know that

The number of guests multiplied by the the number of cans each guest must bring to meet the goal plus the currently cans must be greater than or equal to 1,000 cans

so

The inequality that represent this problem is

565 + 87x ≥ 1000

Solve for x

565 + 87x ≥ 1000

Subtract 565 both sides

87x ≥ 1000 - 565

87 ≥ 435

Divide by 87 both sides

x ≥ 435/87

x≥ 5

therefore, The number of cans each guest must bring to reach the goal must be greater than or equal to 5.

The slope of the given points is equal to -5/2 or -2.5.

A slope is also referred to as gradient and it's typically used to describe both the direction, ratio, and steepness of the function of a straight line based on its coordinates or points.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For the given points P(-6, 16) and Q(2, -4), the slope is given by;

Slope = Δy/Δx

Slope = (-4 - 16)/(2 - (-6))

Slope = (-4 - 16)/(2 + 6)

Slope = -20/8

Slope = -5/2 or -2.5.

For the given points R(-6, 14) and S(-2, 4), the slope is given by;

Slope = Δy/Δx

Slope = (4 - 14)/(-2 - (-6))

Slope = (4 - 14)/(-2 + 6)

Slope = -10/4

Slope = -5/2 or -2.5.

In conclusion, the slope of the line that passes through the given points is equal to -5/2 or -2.5.

Complete Question:

Find the slope of the given points. P(-6, 16), Q(2, -4); R(-6, 14), S(-2, 4)

Rate of change (m) = 10

Starting amount (b) = 14

It takes 9 days to have 104 boondins.

The equation in slope-intercept form is: y = 10x + 14

Its graph is shown below.

Where m represents the rate of change and b represents the y-intercept or starting value, the equation of a line can be written in slope-intercept form as:

y = mx + b.

From the information given, the following are given about the line:

x = number of days

y = total number of boondins

If he had 74 boondins in 6 days and he bought 10 more every day, then:

x = 6

y = 74

Starting value (b) = ?

Rate of change (m) = 10

Substitute the values into y = mx + b to find the value of b:

74 = 10(6) + b

74 = 60 + b

74 - 60 = 60 + b - 60

14 = b

b  = 14

Therefore:

Rate of change (m) = 10

Starting amount (b) = 14

To write the equation in slope-intercept form, substitute b = 14 and m = 10 into y = mx + b:

y = 10x + 14

To find how many days it takes to have 104 boondins, substitute y = 104 into the equation, y = 10x + 14:

104 = 10x + 14

Solve for x

104 - 14 = 10x

90 = 10x

90/10 = 10x/10

9 = x

x = 9

It takes 9 days.

For 10 days, it would take:

y = 10(10) + 14

y = 114 boondins

The table is:

(x, y)

(0, 14)

(10, 114)

The equation with solution zero are : b. 2 (x + 6) = 3 (x + 4) and  d. 3x + 8 = 2x+8.

Here in this problem, we are dealing with linear equations which is a condition of one variable regularly composed within the form ax+b=0 where a and b are real numbers and x is an unknown variable. Solutions to linear equations is refer to a linear equation that can have zero, one, or infinitely numerous solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution simplifies to a solution of the form x=n where n may be a real number. A linear equation with infinitely numerous solutions simplifies to a true statement without a variable such as 1=1.

So in the above-given equations

a. 4x + 1 = 4x - 1 => 4x-4x =1-1 =>0=0

b. 2 (x + 6) = 3 (x + 4)

=> 2x+12=3x+12

=>3x-2x= 12-12

=>x=0

c. 2x + 5 = 11
