Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.
A(-6, 9), B(2, 1); Ratio 5 to 3
Answer:
The coordinates are (-1,4)
Step-by-step explanation:
To get the coordinates, we use the internal division formula
Mathematically, that will be;
(nx1 + mx2)/(m+n) , (ny1 + my2)/(m + n)
In this case;
m = 5
n = 3
(x1,y1) = (-6,9)
(x2,y2) = (2,1)
Substituting these values, we have that;
(3(-6) + 5(2)/(5+3) , (3)(9) + 5(1))/(5 + 3)
= (-18 + 10)/8 , (27+5)/8
= -8/8,32/8
= (-1,4)

The variable z varies jointly with x and y. Also, z = -75 when x = 3 and y = -5.
What equation describes this variation?
z = kxy
What is the constant of variation?
k =
Answer:
Maybe is 2y
Step-by-step explanation:
Step-by-step explanation:
z = kxy, where k is a real constant.
We have z = -75, x = 3, y = -5.
(-75) = k(3)(-5)
-75 = -15k
k = 5.
Which of the following is a solution to the equation 3/4x - 12 = -18?
4.5
-22.5
-40
-8
Answer:
-8
Step-by-step explanation:
3/4x=-18+12
x=-6×4/3
x=-8
Answer:
x = -8
Step-by-step explanation:
[tex] \frac{3}{4} x - 12 = - 18[/tex]
i) multiply both sides of equation with 4
[tex] 4(\frac{3}{4} x - 12) = 4( - 18)[/tex]
[tex](4 \times \frac{3}{4} x) + (4 \times ( - 12)) = - 72[/tex]
[tex]3x - 48 = - 72[/tex]
ii) move -48 to the right-hand side and change its sign
[tex]3x = - 72 + 48[/tex]
iii) calculate the sum
[tex]3x = - 24[/tex]
iv) divide both sides of equation with 3
[tex] \frac{3x}{3} = \frac{ - 24}{3} [/tex]
[tex]x = - 8[/tex]

Use rise over run. Find two points that are at perfect points. For example (3,2). Don't use something like (2.45, 7.34), That will make it difficult. I used (0, 4) and (-3, 4). To get from (-3,4) to (0,4), you have to go up 8 and to the right 3. Always count up or down first and then side to side.
Identify the graph of f(x) = -3 |x+2|.
Answer:
the first one
Have a safe and happy new years
The function f(x) = -3 |x+2| represent the graph A. The correct option is A.
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The function f(x) = -3 |x+2| is an absolute function. On plotting the graph of the function we will get the graph at (-2,0) coordinate and cut the y axis at ( 0,-6 ) coordinate. The graph is attached with the answer below.
Therefore, the function f(x) = -3 |x+2| represent the graph A. The correct option is A.

Is the following relation a function?
Answer:
yes
Step-by-step explanation:
A function is any graph that the x values do not repeat.
You can check this by using this vertical line test
Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

2-(y+2)=3y
PPLLSS AANNDD TTHHXX!!
How to solve your question
Solve for y:
-y = 3 y
Subtract 3 y from both sides:
-y - 3 y = 3 y - 3 y
-y - 3 y = -4 y:
-4 y = 3 y - 3 y
3 y - 3 y = 0:
-4 y = 0
Divide both sides of -4 y = 0 by -4:
(-4 y)/(-4) = 0/(-4)
(-4)/(-4) = 1:
y = 0/(-4)
0/(-4) = 0:

Answer:
non-proportional y-value: 16.5
corresponding proportional y-value: 18
Step-by-step explanation:
Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).
The correct proportional values would be (4.5, 18).

A chef uses 1/2 cup of cheese for a small pizza. There are 6 grams of fat in 1/4 cup of cheese.
Drag one expression next to each question. The correct expression for each row is a way to answer that question.
Drag one expression next to each question. The correct expression for each row is a way to answer that question. PLZZ help!!
Answer:
The correct options are;
1) How many grams of fat are in 1/2 cup of cheese = [tex]6 \div\dfrac{1}{4} \cdot \dfrac{1}{2}[/tex]
2) How many cups of cheese will the chef need to make 13 small pizzas = [tex]\dfrac{1}{2} \cdot 13[/tex]
3) How many small pizzas could the chef make if he has 3/4 cup of cheese is given as follows;
[tex]\dfrac{3}{4} \div \dfrac{1}{2}[/tex]
Step-by-step explanation:
1) How many grams of fat are in 1/2 cup of cheese
The number of grams of fat per 1/4 cup of cheese = 6 grams
Therefore;
The number of grams of fat per kilogram of cheese = 6/(1/4)
The number of grams of fat per 1/2 kilogram of cheese = 6/(1/4) × 1/2, which can be written as follows;
[tex]6 \div\dfrac{1}{4} \cdot \dfrac{1}{2}[/tex]
2) How many cups of cheese will the chef need to make 13 small pizzas
The number of cups of cheese per small pizza = 1/2 cup of cheese
Therefore, the number of cups of cheese in 1 small pizza = 1/2 × 13, which can be written as follows;
[tex]\dfrac{1}{2} \cdot 13[/tex]
3) How many small pizzas could the chef make if he has 3/4 cup of cheese is given as follows;
Given that 1/2 cup of cheese can make one small pizza
(1/2)/(1/2) = 1 cup of cheese can make 1/(1/2) small pizza
3/4 cup of cheese can make 3/4 × 1/(1/2) = (3/4)/(1/2) small pizza, which can be written as follows;
[tex]\dfrac{3}{4} \div \dfrac{1}{2}[/tex]

Graph the line that passes through the points (3,-4) and (3,-1) and determine
the equation of the line.
Answer:
The equation of a line:
x = 3The graph of the line is attached below.
Step-by-step explanation:
Given the points
(3, -4)(3, -1)Finding the slope between (3,-4) and (3,-1)
(x₁, y₁) = (3,-4)
(x₂, y₂) = (3, -1)
Using the slope formula
m = y₂-y₁ / x₂-x₁
= -1-(-4)) / 3 - 3
= -1 + 4 / 0
m = ∞
The slope of the line is undefined, then, by definition, the line would be a vertical line.
As the line that passes through the points (3,-4) and (3,-1)
For a vertical line, the value of x is the same for each and every value of y.Thus, the equation of a line:
x = 3The graph of the line is attached below.
