Please help me asap.
===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates
-----------------
Using that idea for the given vectors leads to
v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
v - w = < 10, 5 >

C.
The solution to this is x ≤ 4.
So then we look at the graphs and choose the correct one.
When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.

2m is term because it is what you are looking for
In the expression 4(2m-n), (2m-n). is a term and In expression 4(2m-n), 2m is also a term. The correct options are B and B for both.
What is a term in an expression?One mathematical expression makes up a term. It could be a single variable (a letter), a single number (positive or negative), or the number of variables multiplied but never added or subtracted.
Variables in certain words have a number in front of them. A term is defined as a single number or single variable or number and variable multiplying with each other in a mathematics expression.
The first expression is 4(2m-n), then in the expression 2m - n will be the term of the expression.
The second expression is 4(2m-n), then in the expression 2m is the term of the expression.
Therefore, the expression 4(2m-n), (2m-n). is a term and In expression 4(2m-n), 2m is also a term.

What is the dependent and independent variable?and
What is the (x) and (y) axis?
Answer:
and independent variable It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. and a Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

Answer:
30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
150 = ?+120
Subtract 120 from each side
150-120 = ?
30 = ?
Answer:
[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]
Step-by-step explanation:
According to exterior angle theorem:
The measure of the exterior angle is equal to the sum of non-adjacent interior angles.
So,
< VST = <STU + <SUT
150 = 120 + <SUT
<SUT = 150-120

A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A. -4 B. -30 C. 4 D. 30
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
C
Step-by-step explanation:
You can work backward to find out the answer!
Start with -9. Instead of multiplying by 3, you can divide.
-9/3 = -3
Now, instead of decreasing -3 by 7, increase by 7.
-3+7 = 4
You get 4, which is C!

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3
Answer:
126 in³
Step-by-step explanation:
Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:
Volume of cylinder = πr²h
Where,
r = radius = ½ of d = ½*4 = 2 in
h = height = 10 in
Take π as 3.14
Plug in the values into the formula
Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

Explain how you find the scale factor using 2-3 sentences or showing each step. Explain using the ratio of the image length to the pre-image length.
Answer/Step-by-step explanation:
The scale factor = the ratio of the corresponding sides of the image and the preimage.
That is, A'B'/AB = B'C'/BC
The preimage is the smaller figure, given as ABCD.
AB = 3 - 1 = 2 units
BC = 4 - 1 = 3 units
The image is the larger figure, given as A'B'C'D'.
A'B' = 9 - 5 = 4 units
B'C' = 7 - 1 = 6 units
Scale factor = [tex] \frac{4}{2} = \frac{6}{3} = 2 [/tex]

Equivalent to 1/2 (36x -14) +(2x-9)?
Answer:
20x - 16
Step-by-step explanation:
We can first do 1/2 (36x - 14), getting 18x - 7.
Then our expression becomes 18x - 7 + 2x - 9.
We can combine like terms, getting 20x - 16.
The vertex of this parabola is at 2, -1 When the y-value is 0 the x value is 5 what is the coefficient of the squared term in the parabola equation.
A. -3
B. -4
C. 4
D. 3
Answer:
[tex]\large \boxed{\sf \frac{1}{9}}[/tex]
Step-by-step explanation:
[tex]\sf y=a(x-h)^2+k[/tex]
[tex]\sf Vertex = (h,k)[/tex]
y-value is 0 and the x value is 5
h = 2
k = -1
[tex]\sf 0=a(5-2)^2+-1[/tex]
Solve for [tex]\sf a[/tex] (the coefficient of the squared term).
[tex]\sf 0=a(3)^2+-1[/tex]
[tex]\sf 0=9a-1[/tex]
[tex]\sf 9a=1[/tex]
[tex]\displaystyle \sf a=\frac{1}{9}[/tex]
The coefficient of the squared term in the parabola equation is 1/9.
Answer:
Fot this parabola the coefficient for squared term is 7
Step-by-step explanation:
The formula for vertex equation is:
x = a*(y-h)^{2}+kx=a∗(y−h)
2
+k
if vertex is at (-3,-1) and in the formula the vertex is (k,h), we replace this values
x = a*(y +1)^{2} -3x=a∗(y+1)
2
−3
The other point of this parabola is (4,0), so we replace it in the formula below:
4 = a*(0 + 1)^{2} -34=a∗(0+1)
2
−3
4 = a*(1)-34=a∗(1)−3
4 +3= a*(1)4+3=a∗(1)
a=7a=7
The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same
what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6
We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5hd, equals, 5, h. How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour?
Answer:
a) 0.2 h
b) 5 cm
Step-by-step explanation:
The given equation is:
[tex] d = 5h [/tex] (1)
Where:
d: is the depth in centimeters
h: is the time in hours
a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:
[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]
Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
b) The depth in centimeters of snow accumulate per hour is:
[tex] d = 5h = 5*1 = 5 cm [/tex]
Therefore, 5 cm of snow accumulates per hour.
I hope it helps you!
