B is the midpoint of AC. C is the midpoint of AD. Find the coordinates of B and D given the coordinates of A (-2,5) and the coordinates of C (8,7).
Answers
B= (3,6) and D= (18,9)
Step-by-step explanation:
To find the midpoint of two given points add X1 and X2 together, then divide by 2 to get the X value of the midpoint and do the same thing for the Y value. That will get you B. From there you can see to get from point A to point C you add 10 to the x value and add 2 to the y value. Because C is the midpoint just double what you had to add to get point D (add 20 to x and add 4 to y)

What are the coordinates of the image of the point (−2, 6) after a clockwise rotation of 90° about the origin?
(−6, −2)
(6, 2)
(2, −6)
Answers
The rule is
(x,y)=(y,-x)So
Our coordinate is (-2,6)
Rotated point
(6,-(-2))(6,2)Option B
Answer:
(6, 2)
Step-by-step explanation:
Rotation rules about the origin:
90° clockwise (or 270° counterclockwise): (x, y) → (y, -x)180° clockwise (or 180° counterclockwise): (x, y) → (-x, -y)270° clockwise (or 90° counterclockwise): (x, y) → (-y, x)Therefore, to rotate (-2, 6) clockwise 90° about the origin:
⇒ (-2, 6) → (6, -(-2)) → (6, 2)
-8y=-4x slope with explanation
Answers
Answer:
slope = 1/2
Step-by-step explanation:
-8y = -4x
y = 1/2x
y = mx
m = 1/2
slope = 1/2
Divide by -8
y = 1/2x
Your slope will be 1/2 because -4 divided by -8 is 1/2

A function is a relation in which no two ordered pairs have the same input (x-values) and different outputs (y-values).
In option 1, x = 1 has two corresponding y-values: -6 and 9. Therefore, the given relation in Option 1 does not represent a function.

Janice buys four boxes of paper clips . She pays with a $ 10 bill and receives $ 6.08 in change . What is the price of one box of paper clips ?
Answers
Answer:
$0.73 per paper clip
Step-by-step explanation:
So to start off you want to find out how much she paid for the paper clips. We know that she paid with a 10 dollar bill and she got $6.08 in change. Now just subtract to find the amount.
10-6.08 which is 2.92
So she paid $2.92 for 4 boxes of paper clips.
The question asks for 1 box So you divide.
2.92/4 which is 0.73
The answer is $0.73 per box of paper clip.

Given that point is the midpoint of CD what additional information will allow for the conclusion that AB is a perpendicular
bisector of CD?
1. CE congruent ED
2. AE congruent EB
3. m
4. m
(< mean angle)
Answers
Answer:
CE congruent ED
Step-by-step explanation:
A perpendicular bisector is a line segment which perpendicularly intersects another line, thereby dividing it into two equal parts. In fact, the Perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment’s endpoints.
The perpendicular bisector, AB, bisects CD at a point E, that is, the length CE is equal to ED. And the angle formed between the two lines is 90 degrees.Therefore, the additional pertinent information that allows for the conclusion that AB is a perpendicular bisector of CD is that "CE congruent ED".
use the intercepts and graph the equation

Answers
Answer:
$6.00 for pair of gloves and $8.00 for a hat
Step-by-step explanation:
the difference between Tori and Cody is $16.00 its two hats. Then one hat is $8.00
If two hats are $16, two pair of gloves must be $12.00
Then one pair of gloves is $6.00

Clay soil has small, fine particles, which is why it retains the most amount of water. Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water. Silt and loam, with medium-size particles, retain a moderate amount of water.

You've learned how to solve linear equations and how to check your solution. In this
lesson, you'll learn that not every linear equation has just one solution. Take a look
at this problem.
Jason and his friend Amy are arguing. Jason says that a linear equation always has just one
solution. Amy says that some linear equations have more than one solution. Who's right?
Amy asked Jason to explore solutions to the following equation
2x + 1 + x = 3x - 2)+7
Use the math you already know to solve this problem.
Remember that a solution to an equation is a number that makes the equation true.
To check to see if a number is a solution to this equation, replace x with its value.

The ratio of Jay age to Hena's age to Sally age is 4:3:6.Jay is 24 years old
(a)Find Sally's age.
(b)What is their total age?
Answers
Answer:
1. Write It Out:
Jay 4: Hena 3 : Sally 6
Jay is 24 years old.
2. Solve
So first you find 24/4 to get 6. This means Jays age was divided by 6 to get his ratio number. Showing that Hena's and Sally's is divided by 6 as well to get there ratios. Now what you need to do is mulitipy Hena and Sallys ratio by six to find there age's.
Hena: 3x6= 18 years old
Sally: 6x6= 36 years old
(Jay: 4x6= 24 years old)
Now to find there total age add them up...
18+36+24= 78
A. Sally is 36
B. 78
Answer:
Sally is 36 years old.
their total age is 78 years.
Step-by-step explanation:
[tex]4 + 3 + 6 = 13[/tex]
that's the total ratio
Jay is 24 years old and his ratio is 4
so assume the total age to be
[tex]x[/tex]
[tex]4 \div 13 \times x = 24[/tex]
[tex]4x \div 13 = 24[/tex]
[tex]4x = 24 \times 13 \div 4[/tex]
[tex]x = 78 \: total \: age[/tex]
t
[tex]sally \: age = 6 \div 13 \times 78[/tex]
