I'm assuming you meant "9c^2 - 4c^2 + 2c^2."  This comes to:

(9 - 4 + 2)*c^2, or 7c^2.

If B is the midpoint of AC, then |AB| = |AC|.

|AB| = 3x + 2

|BC| = 5x - 10

Therefore we have the equation:

3x + 2 = 5x - 10     |subtract 2 from both sides

3x = 5x - 12      |subtract 5x from both sides

-2x = -12      |divide both sides by (-2)

x = 6

The measure of line segment AC is 40 units.

Given that, B is the midpoint of AC.

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.

Since, B is the midpoint of AC, we get

AB=BC

⇒ 3x + 2 = 5x - 10

⇒ 5x-3x=2+10

⇒ 2x=12

⇒ x=6

So, AC=AB+BC

= 3x + 2 + 5x - 10

= 8x-8

= 8(x-1)

= 8(6-1)

= 40 units

Therefore, the measure of line segment AC is 40 units.

Final answer:

To find the hikers' average speed, we use the difference in distance and time between two groups, yielding an average speed of 3.3 miles per hour.

Explanation:

To solve the problem of how fast the hikers are going, we need to calculate the average speed using the distance covered by Sally's group and the time difference between the two groups. The formula for average speed is Average speed = Total distance ÷ Total time.

Let's denote the average speed as v, the distance covered by Marks' group as d (which is the same as Sally's since they start at the same point and hike at the same speed but for different periods), and their respective times as t1 for Marks' group and t2 for Sally's group.

Given:

Sally's group covers 7.7 miles more than Mark's group

t1 = 2.5 hours and t2 = 4.7 hours

Equation: Since they have the same speed, Mark's distance d plus 7.7 miles equals the speed v multiplied by t2 (Sally's hiking time). So, d + 7.7 = v × t2. Also, because speed is constant, v = d ÷ t1. Combining these, we get v = 7.7 ÷ (t2 - t1).

Solution: Substitute the given values into the formula, v = 7.7 ÷ (4.7 - 2.5)

Answer: v = 3.3 miles per hour.

Final answer:

The common difference of the arithmetic sequence with the first term of 5 and the eleventh term of 125 is found to be 12, using the formula for the nth term of an arithmetic sequence.

Explanation:

The student is asking how to find the common difference in an arithmetic sequence where the first term is 5 and the eleventh term is 125. To solve this, we can use the formula for the nth term of an arithmetic sequence, which is given by:

Tn = a + (n - 1)d

where Tn is the nth term, a is the first term, n is the term number, and d is the common difference. In this case, we know that a = 5 and T11 = 125, and we want to find d.

So we can set up the equation 125 = 5 + (11 - 1)d, which simplifies to 125 = 5 + 10d. Solving for d, we get d = (125 - 5)/10 = 120/10 = 12. Hence, the common difference of the arithmetic sequence is 12.

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Answer:

y=0.15x + 77.00

To find out how much vegetable oil Michelle will use, you need to multiply 2 1/2 by 2/3, giving us approximately 1 2/3 cups. The rest will be substituted with applesauce which is approximately 5/6 cups.

In this scenario, Michelle has a recipe that requires 2 1/2 cups of vegetable oil. She wants to use only 2/3 of the total vegetable oil, and use applesauce for the rest. To find out how much vegetable oil she will use, you need to multiply 2 1/2 by 2/3.

But before that, you need to convert 2 1/2 into an improper fraction, where 2 1/2 is equivalent to 5/2. So, the total amount of vegetable oil Michelle will use can be calculated as follows: (5/2) *(2/3) = 10/6 = 5/3 cups.

This means Michelle will use approximately 1 2/3 cups of vegetable oil. To find out the rest of the substitute in applesauce, simply subtract 1 2/3 from 2 1/2. This equals to approximately 5/6 cups of applesauce.

Michelle will use 1 2/3 cups of vegetable oil for her recipe and replace the remaining amount with 5/6 cup of applesauce.

Michelle needs to calculate the amount of vegetable oil to use if she wants to use 2/3 of the amount specified in the recipe, and then find how much applesauce to replace the rest of the oil. The original recipe calls for 2 1/2 cups of oil. Firstly, calculate 2/3 of 2 1/2 cups:

Convert 2 1/2 to an improper fraction, which is 5/2.

Multiply 5/2 by 2/3 to find 2/3 of the mixture, which equals (5/2) × (2/3) = 5/3, or 1 2/3 cups.

This is the amount of vegetable oil Michelle will use. Now for the applesauce:

Subtract 1 2/3 cups from 2 1/2 cups to find the amount to replace with applesauce: 2 1/2 - 1 2/3 = 5/2 - 5/3 = 15/6 - 10/6 = 5/6.

Michelle will use 1 2/3 cups of vegetable oil and 5/6 cup of applesauce.

i believe the answer would be 40 miles

72 people.

50 x 3 = 150

24 x 3 = 72

The length of the base is 10 and the length of each leg is 20.

In order to find this, we can start by making the length of the base x. Now we know that the legs are twice as long, which would make them 2x. Since there are two of them, we can add x + 2x + 2x and set equal to 50 to find the value of x.

x + 2x + 2x = 50

5x = 50

x = 10

Now we can plug this in for our leg length as well to find that.

2x = Leg

2(10) = Leg

20 = leg

Final answer:

The statement that every relation is a function is false, as a function requires each input from the domain to be associated with exactly one unique output in the range, unlike a general relation which can associate a single input with multiple outputs.

Explanation:

A function is a special type of relation where each element in the domain is paired with exactly one unique element in the range. This specificity is illustrated by considering a relation that contains ordered pairs sharing the same first element but with different second elements; such a relation cannot be a function since it violates the definition that each input (domain) must be associated with a unique output (range).

On the other hand, if a relation has pairs where the second elements (outputs) are the same but the first elements (inputs) are distinct, it still qualifies as a function. This is because the foundation of a function's definition pertains solely to the uniqueness of mapping from the domain to the range, without regard to the uniqueness of the range itself.

Hello!

To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.

Since we are given two points, we can use those two points to find two different equations.

Remember that ordered pairs are written as (x, y).

A(-2, 4)

y = -3x + b

4 = -3(-2) + b

4 = 6 + b (subtract 6 from both sides)

-2 = b

A) Therefore, the equation of the first ordered pair is y = -3x - 2.

B(5, 2)

2 = -3(5) + b

2 = -15 + b (add 15 to both sides)

17 = b

B) The equation of the second ordered pair is y= -3x + 17.

Step-by-step explanation:

The perimeter of a polygon is calculated by adding up the lengths of all its sides. In the case of a regular polygon (all sides equal), it's the length of one side times the number of sides. To answer the specific question, each side must be measured and added up.

In mathematics, the perimeter of a polygon is the sum of the lengths of its sides. If the polygon has all equal sides, like a square or regular hexagon, you just multiply the length of one side by the number of sides. If not, you have to add up the lengths of all the sides individually.

For example, if we have a triangle with sides 3, 4, and 5 units long, the perimeter would be 3+4+5 = 12 units. Or, for a square with each side 4 units long, the perimeter would be 4*4 = 16 units. Without seeing the actual polygon in your question, I can't provide the exact perimeter, you’d need to measure each side and add them together or use a formula if it’s a regular shape with equal sides.
