As per the concept of inequality, the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is 15 + 4m ≥ 35

Inequality

Inequality shows a non equal relationship between two numbers or two expressions.

Given,

Jason is training to run in a marathon. His goal for this week is to run a minimum of 35 miles. So far this week, he has already run 15 miles.

Here we need to determine the inequality could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal.

Here we know that, his goal for this week is to run a minimum of 35 miles.

For this week, he has already run 15 miles.

In the given inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal.

=> 15 + 4m ≥ 35

Here we know that, 4m = number of m miles run in 4 days.

Therefore, inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is written as,

=> 15 + 4m ≥ 35

The equation of a straight line can be written if its slope and any one point lying on it is given. The  equation of the line for given slope and point is  (y - 3) = -1 / 7 × (x - 3). The correct answer is option B.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given that,

The slope of the line = -1 / 7

The coordinate of the point on the line = (3,3)

The equation of a line having slope m and passing through a point (x₁, y₁) is given as,

(y - y₁) / (x - x₁) = m

Thus, the equation of the line for given slope and point is given as,

(y - 3) / (x - 3) = -1 / 7

=> (y - 3) = -1 / 7 × (x - 3)

Hence, the equation of the line for given slope and point is  (y - 3) = -1 / 7 × (x - 3).

The simplified expression using the commutative property is in the first option :  1/3 + 2/3 + 3/5   = 1 + 3/5 = 1 3/5 .

now the given expression is 1/3 + 2/3 + 3/5 .

Therefore this expression can be simplified using the commutative property where we put the like terms together.

1/3 + 3/5  + 2/3

= 1/3 + 2/3 + 3/5 (here we use commutative property on the second and third terms of the expression)

= 1 + 3/5 (we know that 1/3 +2/3 = 1)

=1 3/5

Hence by using the commutative property we calculate the sum easily.

The commutative property applies to the arithmetic operations of addition and multiplication. This suggests that no matter how the numbers are arranged or placed, the result of adding or multiplying them remains the same.

As an illustration, 1 + 5 = 6 and 5 + 1 = 6. No matter how two numbers are added, the sum is unaffected. Multiplication uses the same principle. The commutative property does not hold for division and subtraction because the results are completely different when the numbers are rearranged.

Answer: 11 Cents per ounce of Juice

Step-by-step explanation:

The first step here is going to be to find how many ounces are in a gallon. This can be determined as shown using the given information you stated above:

1 gallon * 4 quarts * 2 pints * 2 cups * 8 ounces = 128 ounces in 1 gallon

Step 2 is multiplying 128 ounces by 2 because we have two gallons of juice in the bottle:

128 ounces per gallon* 2 gallons = 256 ounces

Step 3 is dividing the total cost of the juice, which is $28.16, by the number of total number ounces (256)

$28.16 / 256 ounces = .11 dollars per ounce (aka 11 cents per ounce)

The formula that is used to calculate the midpoint for the given two point is written as ( (x₁ + x₂)/2 , (y₁ + y₂)/2).

Mid point:

Midpoint refers the point on a line that is at an equal distance from either end.

Given,

Here we have to explain the concept of midpoint in a simple manner.

According to the definition, midpoint refers the central point between the two points.

So, in a simple manner we have said that the mid point is calculated by finding the average of the two given point.

For example, (x₁, y₁) and (x₂, y₂) are the points, then the midpoint (xₙ, yₙ) is calculated by using the formula,

(xₙ, yₙ) = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)

Similarly, if one point and the midpoint is given, then the another point is calculated by apply the remaining point as (x, y) and solve it accordingly, then we can get the value of it.

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

I Think thatthe answer is 2

The equation which relates the number of triangles in figure (n) to the perimeter of the figure (P) is P = 6n + 18. Option A is correct.

We are given:

The perimeter of the 1 triangle = 24

The perimeter of the 2 triangle = 30

The perimeter of the 3 triangle = 36

As we can see in the given figures two sides with lengths of 9 are fixed and the side with a length of 6 is varying.

So, we can write this as,

P = 6n + 18, where n = number of triangles.

Now, check the equation formed by substituting the values;

Substitute n = 1, and we get;

P = 6(1) + 18

P = 6 +18

P = 24 True.

Substitute n = 2, and we get;

P = 6(2) + 18

P = 12 +18

P = 30 True.

Substitute n = 3, and we get;

P = 6(3) + 18

P = 18 + 18

P = 36, true.

So, it is true for all the figures.

Thus, the equation which relates the number of triangles in figure (n) to the perimeter of the figure (P) is P = 6n + 18. Option A is correct.

Given, f(x) = [tex]x^{2} +6x[/tex]

x(x+6) = 0

x = 0    x+6 = 0

Putting values of x in equation,

For x = 0

f(x) = [tex]0^{2}+6(0)[/tex]

Therefore, (0,0)

For x = -6
