Answer:
(2, -5)
Step-by-step explanation:
Using the midpoint formula - M= [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1}+y_{2} }{2} )[/tex], we get that the x value of the point is 2 and the y-value of the midpoint is -5, so the midpoint of segment ST is (2, -5)

“8 minus the quantity b divided by 6.”
The Sears Tower in Chicago is 1,454 feet tall. It is 204 feet taller than the Empire State Building in New York City. Use the equation e + 204 = 1,454 to find the height of the Empire State Building
equation a. 100x-10x+270=5670
Answer:
60
Step-by-step explanation:
90x + 270= 5670
90x=5670-270
x=5400÷90
x=60
Answer:
x = 60
Step-by-step explanation:
1) 100x - 10x + 270 = 5670
2) 100(60) - 10(60) + 270 = 5670
3) 6000 - 600 + 270 = 5670
4) 5400 + 270 = 5670
5) 5670 = 5670
All I really did was input random numbers for the value of "x", then add 270 at the end of an equation. If that method works for me, it should work for everyone, including you.

Find the equation of the line that is perpendicular to the line
6x – 4y = 3 and passes through the point (6,-1).
(a) Find the slope of the given line 6x – 4y = 3.
(b) What is the slope of a line that is perpendicular to the above line?
(c) Now, find the equation of the perpendicular line that passes through (6,-1).
Answer:
a). y = 3/2x - 3/4 b).-2/3 c).y = -2/3x + 3
Step-by-step explanation:
a). 6x – 4y = 3
-4y = -6x + 3
y = 3/2x - 3/4
- The slope is 3/2.
b). The slope of a perpendicular line would be the opposite: -2/3
c). y = -2/3x + b
-1 = -2/3(6) + b
-1 = -4 + b
3 = b
y = -2/3x + 3

what is a bar plot, and what do the vertical lines on a bar plot represent?
Answer:
If you know what a graph looks like, then it is similar looking if not almost the same. The vertical lines represent what ever your x value is, in example the number of toys you have to how much they cost(ed) your x value would be the number of toys you have.
Step-by-step explanation:
Answer: a bar plot is a type of graph. The vertical lines shows the amount/data.
May contain dates that show how many each day, month, year.
The way most teachers show this is with what people prefer like, favorite color, food, etc...

Which equation in standard form has a graph that passes through the point (0, -5) and has a slope of 3/4?
A)3x + 4y = -20
B)3x - 4y = 20
C)4x + 3y = 20
D)4x - 3y = -20
Answer:
B) 3x - 4y = 20
Step-by-step explanation:
We can eliminate C and D since 4(0) + 3(-5) = -15 (not 20) and 4(0) - 3(-5) = 15 (not -20)
Now we will determine the slopes for A and B to see which one is correct:
A) 3x + 4y = -20 -> 4y = -20 - 3x -> y = -5 - 3/4x -> y=-3/4x - 5 (not right)
B) 3x - 4y = 20 -> -4y = 20 - 3x -> y = -5 + 3/4x -> y = 3/4x - 5 (right)
Therefore, B is correct since the slope is 3/4 and passes through (0,-5)

Hikers walk 3 miles east and then 2 miles north and take a water break. They continue
hiking 4 miles east and a final 2 miles south to their destination. What single
transformation took place from their starting position to their final destination? Use
mathematical language and create a graphic to explain your answer. Be sure to use a
straight edge and grid paper for your graphic to represent this problem.
The single transformation that took place from their starting position to their final destination is (x, y) ⇒ (x + 7, y)
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point either up, down, left or right in the coordinate plane.
Hikers walk 3 miles east and then 2 miles north and take a water break. Hence:
(x, y) ⇒ (x + 3, y + 2)
They continue hiking 4 miles east and a final 2 miles south to their destination:
(x, y) ⇒ (x + 3 + 4, y + 2 - 2) ⇒ (x + 7, y)
The single transformation that took place from their starting position to their final destination is (x, y) ⇒ (x + 7, y)

Three consecutive integers have a sum of 30. Which equation can be used to find x, the value of the smallest of the three numbers? (x + 1) + (x + 2) = 30 x + (x + 1) + (x + 2) = 30 x (x + 1) (x + 2) = 30 3 x (x + 1) (x + 2) = 30
Answer:x + (x +1) + (x +2)= 30.
Step-by-step explanation:Consecutive means one right after the other--such as 4,5,6. So the sum (add all the numbers together) must equal 30. So the equation should read

the answer is 294
Step-by-step explanation:
Express the product of (x + 1) and (3/2x+5/3)as a trinomial in simplest
form.
The product of the given expression (x + 1)(3/2x+5/3) is 3/2x² + 29x/6.
What are mathematical operations?A mathematical "operation" is the process of calculating a value using operands and a math operator.The supplied numbers or operands must follow specific guidelines associated with the math operator's symbol.Arithmetic operators perform the operations of addition, subtraction, multiplication, division, exponentiation, and modulus.So, (x + 1)(3/2x+5/3):
Now, solve as follows:
(x + 1)(3/2x+5/3)x(3/2x+5/3) + 1(3/2x+5/3)3/2x² + 5/3x + 3/2x + 5/33/2x² + 2(5)x + 3(3)x + 2(5)x/63/2x² + 10x + 9x + 10x/63/2x² + 29x/6Therefore, the product of the given expression is 3/2x² + 29x/6.

Please help!!!I don’t know this
Step-by-step explanation:
I guess we are only talking about quadratic functions/equations here.
the world is not unified regarding what is the standard form of a quadratic equation.
but let's assume your teacher means
standard form
f(x) = y = ax² + bx + c
vertex form
f(x) = y = a(x - h)² + k
so, we are using the provided x, y coordinates to get a, b and c.
3.75 = a×0.125² + b×0.125 + c
3 3/4 = a×(1/8)² + b×(1/8) + c
15/4 = a/64 + b/8 + c
15×16/64 = a/64 + 8b/64 + 64c/64
=> 240 = a + 8b + 64c
4 = a×0.25² + b×0.25 + c
4 = a×(1/4)² + b×(1/4) + c
4 = a/16 + b/4 + c
4×16/16 = a/16 + 4b/16 + 16c/16
=> 64 = a + 4b + 16c
3 = a×0.5² + b×0.5 + c
3 = a×(1/2)² + b×(1/2) + c
3 = a/4 + b/2 + c
3×4/4 = a/4 + 2b/4 + 4c/4
=> 12 = a + 2b + 4c
we have now from the third equation
a = 12 - 2b - 4c
we put this into the second equation
64 = (12 - 2b - 4c) + 4b + 16c = 12 + 2b + 12c
32 = 6 + b + 6c
26 = b + 6c
b = 26 - 6c
and therefore
a = 12 - 2(26 - 6c) - 4c = 12 - 52 + 6c - 4c = 2c - 40
this a and b we use now in the first equation
240 = (2c - 40) + 8(26 - 6c) + 64c =
= 2c - 40 + 208 - 48c + 64c = 18c + 168
72 = 18c
c = 4
b = 26 - 6×4 = 26 - 24 = 2
a = 12 - 2×2 - 4×4 = 12 - 4 - 16 = -8
so, the standard form is
f(x) = y = -8x² + 2x + 4
the vertex form
we get this by transforming the standard form.
e.g. by competing the square :
y - 4 = -8x² + 2x = -8(x² - x×1/4)
y - 4 -8×(1/8)² = -8(x² -x×1/4 + (1/8)²)
y - 4 - 8/64 = -8(x - 1/8)²
y - 32/8 - 1/8 = -8(x - 1/8)²
y - 33/8 = -8(x - 1/8)²
y = -8(x - 1/8)² + 33/8

■. What is asked: It asks us to find out the greatest number of marbles that rey can put equally inside each box.
■. What is it's Solution:
Before, i will start the solution first you shall need to know about, what is GCF ?GCF stands for the Greatest common factor. Now, i shall ask you: What is the GCF of 36 and 60. The ans will be: 12. How did i get answer 12 ? For that, find the factors of both numbers 36 and 60. then for finding GCF, multiply those factors which are common in both 36 and 60. ( See in the above attachment )■. Now the Solution Starts:
Find the GCF of 27, 36 and 54. ( See in my right side of the attachment ).You will find the GCF = 9. That means, 9 is the greatest number of marbles that he can put equally inside each box.Hence, the required ans: 9.Things you should know about:
What is HCF, GCD ( or GCF ) and LCF ? ( in my answer, I had explained GCF ).Don't confuse that HCF and GCF are same. HCF is mathematical term used in British English ( UK ) and GCF is also a mathematical term similar to HCF used in American English ( USA ). HCF = Highest Common Factor, GCF = Greatest Common Factor and LCF = Lowest Common Factor.If you find anymore doubts regarding on my answer. then plz send your queries to the comment section. i will help you ;))
