what is the midpoint of the vertical line segment graphed below?

x = 1, y = - 4

substitute y = - 4x into the other equation

x - 4x = - 3

- 3x = - 3 ( divide both sides by - 3 )

x = 1

substitute x = 1 into y = - 4x ⇒ y = - 4

3m^2 (10+m)

Use FOIL

3m^2*m=3m^3

3m^2*10= 30m^2

Answer: 3m^3 + 10m^2

Solution :

Given expression [tex]3m^{2}(10+m)[/tex]

To simplify this expression, first we need to know about the Distributive property.

Distributive Property: [tex]a\times(b+c)=(a\times b)+(a\times c)[/tex]

Given expression [tex]3m^{2}(10+m)[/tex]

Applying Distributive property on this expression -

[tex]\Rightarrow 3m^{2}(10+m)=(3m^{2}\times10)+(3m^{2}\times m)[/tex]

                                       [tex]= 30m^{2}+3m^{3}[/tex]

Simplified form of [tex]3m^{2}(10+m)[/tex] is  [tex]30m^{2}+3m^{3}[/tex]

Subtract the difference from the total:

575,000,000 - 350,000 = 574, 650, 000

Divide the difference by 2:

574, 650, 000 / 2 = 287,325,000

That is the lower one, then add the difference for the higher one:

Restaurant A = $287,325,000 + $350,000 = $287, 675,000

Restaurant B = $287,325,000

$2.60 was spent on a box of crackers.  s = 20 students.

Let's have C be the cost of crackers for each student.  To find the cost, we divide the total amount of money (2.60) by the number of students (20)

C = 2.6/20

C = 0.13

The cost of the crackers for each student in Mr. McKay's class, if divided evenly, would be $0.13 when there are 20 students.

Mr. McKay's expenditure on the box of crackers can be written as an arithmetic expression where the total cost is divided by the number of students. This expression is 2.6 / s. By substituting the given number of students (s=20), we find that the cost of the crackers for each student is 2.6 / 20 = $0.13. Therefore, each student should pay $0.13 if the cost of the crackers is to be divided evenly among them.

We are given original selling price of book = $b.

Price is marked down by 46%.

46% can be written as 46/100 in decimals it would be 0.46.

Therefore, markdown as a decimal is 0.46

Now, markdown is 0.46 of original price = 0.46b

Therefore, new price after marked down can be written by expression =

b - 0.46b = 0.56b.

If original retail price was = $29.00.

The sale price would be 0.56b = 29*0.56 = $15.66.

Total saving = 29-15.66 = $13.34.

Therefore, you save $13.34 by paying the sale price $15.66.

Where does 56 come from ?

The maximum miles that she can travel 63 miles before she can walk.

Final answer:

By setting up an equation that accounts for the cab's base fare and the additional per mile charge, we can determine that Erica can afford to travel a maximum of 63 miles in the cab before exceeding her budget of $25.05.

Explanation:

To determine the maximum number of miles Erica can travel in a cab without exceeding her budget of $25.05, we can create an equation where the cost of the cab is equal to the base fare plus the per mile charge times the number of miles (mileage). We know the base fare is $3 and the per mile charge is $0.35. Let's denote the number of miles Erica can travel as 'm'.

The cost equation would be: Cost = Base Fare + (Per Mile Charge × Mileage)

This gives us: $25.05 = $3 + ($0.35 × m)

Subtracting the base fare from both sides gives us: $22.05 = $0.35 × m

Dividing by the per mile charge yields: m = $22.05 / $0.35

Calculating this, we get: m = 63 miles

Therefore, Erica can travel a maximum of 63 miles in the cab before she would need to walk the rest of the way to the museum to stay within her budget.

g. Equilateral

h. Scalene

i. Equilateral

Here's the type of triangle for each set of measurements:

d. 45 cm, 61 cm, 60 cm:

All sides are different lengths.

Therefore, this is a scalene triangle

e. 30 cm, 31cm, 30 cm:

Two sides have equal lengths (30 cm).

This is an isosceles triangle

f. 4 cm, 5ft, 4 cm:

We need to convert feet to the same unit as cm for comparison.

1ft = 12 inches = 2.54 cm

5ft = 5 * 2.54 cm ≈ 12.7 cm

We have two sides with equal length (4 cm) and one different length (12.7 cm).

This is also an isosceles triangle

g. 89mm, 89mm, 89mm:

All three sides have the same length.

This is an equilateral triangle, a special type of isosceles triangle where all sides are equal.

All sides have different lengths.

This is a scalene triangle

i. 22cm, 22cm, 22in:

We need to convert inches to centimeters for comparison.

22in = 22 * 2.54 cm ≈ 55.88 cm

Comparing the converted lengths, we see all sides have equal lengths.

This is an equilateral triangle

The answer is 3.26             :D :D :D :D    

The answer to rounding the number 3.2649 to the nearest hundredth is 3.26. You need to consider the digit in the thousandths place to determine if you round up or down.

To round the number 3.2649 to the nearest hundredth, you will need to look at the digit in the thousandths place, which is 4 in this case. In rounding, if the digit is 5 or more, you round up, else you round down. Here it is 4, it's less than 5, so we round down. So, the number 3.2649 when rounded to the nearest hundredth is 3.26.

Answer:

154 LBS

Step-by-step explanation:

1 KG = 2.2 LBS

70 KG X 2.2 = 154

To convert kilograms to pounds, you divide the weight in kilograms by 0.4536. So, a person weighing 70 kg would weigh approximately 154.32 lbs.

The subject you're asking about is conversion from kilograms to pounds. A weight of 1 lb is equivalent on Earth to a mass of 0.4536 kg. So, to convert kilograms to pounds, you would divide the weight in kilograms by the equivalent mass of 1 pound in kilograms.

For example, a person weighing 70 kg would weigh approximately 154.32 pounds. This was calculated by dividing 70 kg by 0.4536 kg per pound (70/0.4536 = 154.32 pounds). It's important to note that while weight can vary slightly depending on location due to differences in gravitational pull, this conversion factor still provides a good estimation for most common situations.

To solve the question, we need to set up an equation using the information given. Here's a step-by-step explanation:

The value of function f(x - 1) = 2x² + 4x + 5 is not true.

Here,

The function is given as;

f (x) = 2x² + 3

And, f(x - 1) = 2x² + 4x + 5

We have to check the value of f(x - 1) is true or not.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Now,

The function is;

f (x) = 2x² + 3

To determine the value of f (x - 1), we can put (x -1) in place of x as;

f (x) = 2x² + 3

f (x - 1) = 2(x - 1)² + 3

f (x - 1) = 2(x² + 1 - 2x) + 3

f (x - 1) = 2x² + 2 - 4x + 3

f (x - 1) = 2x² - 4x + 5

Hence, The value of function f(x - 1) = 2x² + 4x + 5 is not true.

The required inverse function would be f⁻¹(x) = x / 3, which is the correct answer would be option (C).

The inverse function is defined as a function obtained by reversing the given function.

To determine the inverse of a function, all you have to do is switch where x and y are and resolve for y.

We have to find the inverse of the function below :

f(x) = 3x

So after switching x and y,

Now, we solve for y regularly.

f(x) = x = 3y

Solve for y :

⇒ x = 3y

⇒ x / 3 = y

⇒ y = x / 3 = f⁻¹(x)

Therefore, the required inverse function would be f⁻¹(x) = x / 3.

Hence, the correct answer would be an option (C).

Slope m = y2-y1/x2-x1

Points (-1,3) and (2,-5)

M= -5-3/2-(-1)

M= -8/3

M= -8/3

Slope is -8/3

Now fill in the formula equation of a line using one if the points and slope to find b .

(2,-5) and slope -8/3

Y=mx+b

-5=-8/3(2)+b

-5=-16/3+b

-5+16/3=b

1/3=b

Now put all together

Y= -8/3x+1/3

Slope intercept form of a line is y = mx + b, where m is the slope and b is the y coordinate of the y intercept.

The easiest way to solve this problem is by using another equation for a line, also known as point slope form. This equation is best to use for a line if you have  a point and slope of the line, but do not have the y-intercept.

We need to find the slope of this line passing through the pair of points (-1, 3) and (2, -5). We can do this by using the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute in the appropriate coordinates.

[tex]\frac{-5-3}{2-(-1)}[/tex] = [tex]\frac{-8}{3}[/tex], so the slope of the line is -8/3.

Point slope form of a line is [tex]y-y_1=m(x-x_1)[/tex]. Substitute -8/3 for m, and use the point coordinate (-1, 3) for y1 and x1. You could use either point coordinate but I chose to use this one.

[tex]y-3= -8/3[x-(-1)][/tex]

Distribute -8/3 inside the parentheses.

[tex]y-3= -8/3x - 8/3[/tex]

Add 3 to both sides.

y = -8/3x + 1/3 is your answer (slope intercept form).
