Answer
the answer would be
D(5,-2).
Answer:
D(-6, 1)
Step-by-step explanation:
To determine the solution we can start by calculating the slope of AB;
A(-1, 4), B(2, -5)
m = -5 - 4 / 2 - (-1) = -9 / 3 = -3
Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that is the correct option.
Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;
C(3, 4), D(-6, 1)
m = 1 - 4/- 6 - 3 = -3/-9 = 1/3rd
Correct, as you can see
So your solution is option c

D
Step-by-step explanation:
We know that for every 81 girls, there are 72 boys so how do u get 81? You'd have to multpify 9x9 = 81 and 8x8= 72 so the ratio is 8:9
Daniela got 78% on her last history test. If there were 50 questions on the test , how many did she get correct
Answer:
39.
Step-by-step explanation:
78% of 50 is 39. To calculate x% of a number y, we use the following rule: x% of y = (x / 100) × y.
Factor 72x−18xy
Find the Factor of 72x-18xy
Answer:
4x and (1-y)
Step-by-step explanation:
4x(1-y)
this is my answer
The factors of the expression are 18x and 4-y
Given the expression 72x - 18xy
Find the factor of each term:
72x = 18 * 4 * x
18xy = 18 * x * y
Since 18x is common to both terms, hence the factored form is expressed as:
72x - 18xy = 18x (4 - y)
The factors of the expression are 18x and 4-y

Can I get help solve to find X?
==========================================
Explanation:
The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.
All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.
Set 2x+32 equal to 60 and solve for x
2x+32 = 60
2x = 60-32
2x = 28
x = 28/2
x = 14
As a check,
2x+32 = 2*14+32 = 28+32 = 60
which helps confirm the answer.

Answer:
x = 5

Step-by-step explanation:
Step 1: Define Equation
3x - 6 = 9
Step 2: Solve for x
Add 6 to both sides: 3x = 15Divide 3 on both sides: x = 5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(5) - 6 = 9Multiply: 15 - 6 = 9Subtract: 9 = 9Here we see that 9 does indeed equal 9.
∴ x = 5 is the solution to the equation.

Ducklings cost $15 each. Chicks cost $12 each. You have $60 to spend on poultry
Answer:
If your question is how much money you have after you purchase a duckling and a chick, your answer would be $33. It seems to me like you posted the question without finishing it. I'm guessing you were about to mention how many ducklings and chicks you were going to buy and how much money you would have leftover for the poultry.
Step-by-step explanation:
To solve your problem you must add what you're buying and then subtract from your original amount.
For example: if you want one duckling and one chick and you would like to know how much money you have leftover to buy poultry. $15 + $12= $27 dollars in all. Then, you will subtract $27 dollars from $60, this way you know how much money you will have left in order to buy the poultry. $60 - $27= $33.

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?
Answer:
138.5°
Step-by-step explanation:
A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.
Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.
Joe ate one slice of pie that contained exactly 5 peaches, hence:
Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°
Angle measure of slice = (5 / 13) * 360°
Angle measure of slice = 138.5°
