The midpoint of line segment AB is M(3,-1). If the coordinates of A(8,4), what are the coordinates of B?
The coordinates of B are (-2 , 9)
Step-by-step explanation:
A (8, 4)
M (3 , -1)
To calculate a midpoint you have to add the corresponding coordinates of each point and divide them by 2
(Ax + Bx) / 2 = Mx
(8 + Bx) / 2 = 3
8 + Bx = 3 * 2
Bx = 6 - 8
Bx = -2
(Ay + By) / 2 = My
( -1 + By) / 2 = 4
-1 + By = 4 * 2
By = 8 + 1
By = 9
The coordinates of B are (-2 , 9)
cuanto es 1500x830 +321
The given expression 1500 x 830 + 321 can be solved as 12,45,321 using arithmetic operations.
What is multiplication and addition?Multiplication is the repeated addition of a number. If we multiply m by n, that means m is repeatedly added to itself for n times. The symbol for multiplication is ‘×’.
Addition is the process of combining two or more items (or numbers) to create a new sum.
Given the expression: 1500 x 830 + 321
Using BODMAS, first we do the multiplication.
So, 1500x 830 = 12,45,000
Now, continuing with the addition, we get
12,45,000 + 321 = 12,45,321
Therefore, the given expression can be solved as 12,45,321.

How do you determine whether to use plus or minus signs in the binomial factors of a trinomial of the form x^2 + bx + c where b and c may be positive or negative numbers?
The rule of signs in binomial factors given a trinomial in the form :
[tex]x^2\pm bx\pm c[/tex]Note that b and c can be positive or negative.
And the factor may be :
[tex](x\pm m)(x\pm n)[/tex]First thing to do is to check the sign of c.
If it is positive, the signs of m and n can be both positive or both negative.
Since positive multiplied by positive is positive and
negative multiplied by negative is also positive.
[tex]\begin{gathered} (+)\times(+)=+ \\ (-)\times(-)=+ \end{gathered}[/tex]If the sign of c is negative, one of the factors must be negative and the other must be positive, because negative multiplied by positive is negative.
[tex](-)\times(+)=-[/tex]After considering the sign of c, next to check is the sign of b.
Case 1 :
If b and c are both positive, we know that the factors can be both negative or both positive.
And since the sign of b is positive, we must follow the sign of it which is positive.
So both m and n are positive
For example :
[tex]x^2+5x+6[/tex]The factor will be :
[tex](x+2)(x+3)[/tex]which are both positive.
Case 2 :
If b is negative and c is positive, we will follow the sign of b. m and n will be both negative.
For example :
[tex]x^2-5x+6[/tex]The factors are :
[tex](x-2)(x-3)[/tex]which are both negative
Case 3 :
Now the third case is tricky.
If c is negative, we know that one of m and n is negative and the other one is positive.
The sign of the larger number between m and n will follow the sign of b.
For example :
[tex]x^2-x-6[/tex]c is negative, so one factor must be negative and the other must be positive. The sign of b is negative, so the larger factor must be negative also.
The factor will be :
[tex](x-3)(x+2)[/tex]3 is larger than 2, so the negative sign of b will proceed to the factor 3.

What is division?Division is the process of dividing a bunch of items into equal portions. It is one of the four fundamental operations in mathematics and results in a just distribution of resources. The division of two numbers can be calculated using the following formula: Dividend Divisor = Quotient + Remainder. The number that is being divided in this case is known as the dividend. The number that divides the number (dividend) into equal parts is known as the divisor. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each. The division sign, "÷" or occasionally "/," is used in computer code.

You separate bulbs of garlic into two groups. One for planting and one for cooking. The tape diagram represents the ratio of bulbs for planting to bulbs for cooking. You use six bulbs for cooking. Each bulb has 8 cloves. How many cloves of garlic will you plant.
The number of cloves of garlic you will plant is 288
Given,
There are two groups of garlic bulbs.
Ratio of garlic bulbs = Planting : Cooking = 6 : 1
The number of garlic bulbs used for cooking = 6
The number of cloves in a garlic bulb = 8
We have to find the number of cloves of garlic used for planting:
Here,
Ratio = 6 : 1
1 in ratio represents 6 bulbs of garlic
So, 6 will be, 6 × 6 = 36
That is, the number of garlic bulbs used for planting is 36.
Now,
Number of cloves of garlic used for cooking = 6 × 8 = 48 cloves
Number of cloves of garlic used for planting = 36 × 8 = 288 cloves.

Slope intercept form is y=mx + b
Rewrite your equation in this form
-10y = -8x - 60
Find GCF (Greatest Common Factor) in this case it is 2
Divide all by 2
-5y = -4x - 30
divide both sides by -5
y = 4/5x + 6
slope = 4/5
Answer:

so we know the formula of a line is y=mx+b
1. arrange 8x+10y=60 into y=mx+b format
2. 10y=8x+6
3. we see that 8 = m

The graph shows the relationship between the number of cups of flour and the number of cookies made. Write an equation for the proportional relationship.
The equation for the proportional relationship is 16x-y=0 .
The equation of the line passing through the two points (a,b) and (c,d) is given by
(y-b) = m(x-a), where m is the slope .
In the question ,
Given in the graph that
x represents the number of cups of flour and y represents the number of cookies made .
From the graph we can see that
when 6 cups of flower is used , 96 cookies are made
So, the point on the line is (6,96),
when 12 cups of flower is used , 192 cookies are made
So, the point on the line is (12,192)
hence the line passes through the two points (6,96) and (12,192).
So the slope of the line is
m=(192-96)/(12-6)
m= 96/6
m=16
Substituting the values of a,b, c,d and m in the equation of line formula ,we get
y-96=16(x-6)
y-96 = 16x - 96
16x-y=96-96
16x-y=0
Therefore , The equation for the proportional relationship is 16x-y=0.

What in mathematics is a quadratic equation?
x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might believe that x = 11, but keep in mind that x might also be negative because negative numbers can be squared.

What is Slope ?
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run". It is denoted by "m".
Formula, m = rise / run = (y2 - y1) / (x2 - x1)
Given,
(x1, y1) = (4, 7)
(x2, y2) = (7, 16)
Now, put these values in slope (m) formula,

A rectangular garden is 5 ft longer than it is wide. Its area is 300 ft. What are its dimensions?
The dimensions of the garden are l=20 ft and w=15 ft.
Given, the rectangular garden is 5 ft longer than it's width.
The area of the garden is 300 ft.
dimensions of the garden are = ?
let the width be represented by x.
therefore, length = 5+x
area of the rectangle = l×w
substitute the values.
x(5+x) = 300
5x + x² = 300
x² + 5x - 300 = 0
x²+20x-15x-300 = 0
x(x+20)-15(x+20)=0
(x+20)-(x-15)=0
x=-20 or x=15
hence the dimension cannot be negative.
hence x=15.
substitute x=15 in l=x+5
l=15+5
l=20
Therefore, length and width of the rectangle garden are 20 ft and 15 ft, respectively.
