The midpoint of AB is M (4,2). If the coordinates of A are ( 6,-4) what are the coordinates of B?
The coordinates of point B are calculated using the midpoint formula. Substituting given values for points A and M allows us to find B's coordinates, which are (2, 8).
Explanation:The midpoint of a line segment is calculated using the formula M=(x1 +x2)/2, (y1+y2)/2 where x1 and y1 are the coordinates of the first point and x2, y2 are the coordinates of the second point. Given that the coordinates of point A are (6,-4) and the coordinates of the midpoint M are (4, 2), we can set up the following equations to solve for the coordinates of point B (x2, y2): (6+x2)/2 = 4 and (-4+y2)/2 = 2. Solving for x2 and y2 gives us the coordinates of Point B: (2, 8).

what are three ways you can solve a proportion?
In this exercise we have to explain the three possible methods of solving a proportion, as follows:
1) Vertical
2)Horizontal
3)Diagonal
What is proportion?It is the equality between two or more ratios derived from measurements extracted from quantities. When two ratios have the same result, we say they are proportional. If these ratios represent measures of some magnitude, we also say that they are proportional.
So we know that a proportion is given by the equality between two ratios and the resolution process consists of the following situation: “the product of the extremes is equal to the product of the means” or using the eventual cross multiplication.

a gallon of chocolate milk sells for $3.14. a snack-size bottle of chocolate milk sells for 3 cents per ounce. which is a better buy?
A gallon of chocolate milk will cost less than snack size bottle so it will be better to buy.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Another example could be kilo gram to gram.
Given,
1 gallon ↔ $3.14
Since, 1 gallon = 128 ounce and $1 = 100 cents
128 ounce ↔ 314 cents
So,
1 ounce ↔ 2.453 cents
Now,
Snack-size bottle cost ⇒
1 ounce ↔ 3 cents.
Hence " a gallon of chocolate milk is cheap and batter to buy".

To meet building codes, a building must have a roof no taller than 74 feet. An architect is designing a museum with a 14 ½ foot ground floor, and 12 foot 3 inch upper floors (including supports) How many floors, including the ground floor, can the building have?
Answer:
Building can have 4 floors.
Step-by-step explanation:
Height of the ground floor is 14.5 foot and height of upper floors = 12 foot 3 inches or 12.25 foot per floor
Let there are x floors in the building.
Total height of the building = 74 foot
Therefore, total height of the building = Height of the ground floor + Height of the upper floors
74 = 14.5 + 12.25x
74 - 14.5 = 12.25x
12.25x = 59.5
x = [tex]\frac{59.5}{12.25}[/tex]
x = 4.9 floors
Therefore, the building can have 4 floors.

Show how to solve the problem 378 times 6 using place value with regrouping. Explain how you knew when to regroup
Answer:
2268
Step-by-step explanation:
We have to solve the problem 378 dimes 6 using place value.
Place of 8 in 378 = once
Place of 7 in 378 = Tens
Place of 3 in 378 = Hundred
Now we can write this number as ( 300 + 70 + 8 )
( 300 + 70 + 8 ) × 6 = (300) × 6 + 70 × 6 + 8 × 6
= 1800 + 420 + 48
= 2268

What is quadratic trinomial?It is a type of polynomial which contains three terms and the power of the polynomial is two.The general form of quadratic trinomial is [tex]ax^{2} +bx+c[/tex], where a, b, c are non zero real numbers and x is variableFor given example,
We have been given two quadratic trinomials (2x^2 - 5x + 7) and (4x^2 + 2x - 11).
If (2x^2 - 5x + 7) is subtracted from (4x^2 + 2x - 11),
= (4x^2 + 2x-11) - (2x^2 - 5x + 7)
= 4x^2 + 2x - 11 - 2x^2 + 5x - 7
= (4 - 2)x^2 + (2 + 5)x - (11 + 7)
= 2x^2 + 7x - 18
