Answer:
y - 4 = 2/3(x - 2)
Step-by-step explanation:
The format for point-slope form is: y - y₁ = m(x - x₁)
where m is the slope, x₁ is the x-coordinate and y₁ is the y-coordinate.
In (2,4), 2 is the x-coordinate and 4 is the y-coordinate.
The slope is 2/3.
When you plug in the values, you get:
y - 4 = 2/3(x - 2)

Solve the following problem: Find x, y
Answer:
x=? y=?
Step-by-step explanation:
these two triangles are similar so since the bottom side was 8 and became 10 it added 2 so therefore if you add 2 to the 5 and 7 you get
5+2=7
7+2=9
The value of 'x' is 5/4 and the value of 'y' is 7/4 and this can be determined by using similar triangle properties.
Given :
Two triangles are given in the figure.
The following steps can be used in order to determine the value of 'x' and 'y':
Step 1 - According to the given figure, both the triangles are similar.
Step 2 - So, the value of 'x' and 'y' can be calculated as:
[tex]\dfrac{5}{5+x}=\dfrac{7}{7+y}=\dfrac{8}{10}[/tex] --- (1)
Step 3 - Now, solve the above equation for 'x'.
[tex]\begin{aligned}\\{\dfrac{5}{5+x}&=\dfrac{8}{10}\\50&=40+8x\\x&=\dfrac{5}{4}\\\end{aligned}[/tex]
Step 4 - Now, solve the equation (1) for 'y'.
[tex]\begin{aligned}\\{\dfrac{7}{7+y}&=\dfrac{8}{10}\\70&=56+8y\\y&=\dfrac{7}{4}\\\end{aligned}[/tex]
The value of 'x' is 5/4 and the value of 'y' is 7/4.

Answer:
Would be 75.36
Step-by-step explanation:
Formula: V = πr^2 h (replace pi with 3.14)
(r × r)
= 3.14 × r^2 × h
(r^2 × h = #)
= #π (# × π)
= V
Answered Form: V = π2^2 6
(2 × 2)
= 3.14 × 2^2 × 6
(4×6 = 24)
= 24π (24 × 3.14)
V = 75.36

the greatest common divisor of positive integers $m$ and $n$ is $8$. the least common multiple of $m$ and $n$ is $112$. what is the least possible value of $m n$?
Given the greatest common divisor and the least common multiple, the least possible value of mn is 896
How to determine the least possible value of mn?The given parameters are:
M and N are positive integers
Greatest common divisor = 8
Least common multiple = 112
As a general rule;
The product of the greatest common divisor and the least common multiple of numbers represent the product of the numbers
This means that
mn = Greatest common divisor * Least common multiple
So, we have
mn = 8 * 112
Evaluate
mn = 896
Hence, the least possible value of mn is 896

What is a dimension?A dimension is a measurement that includes length, width, and height. When you discuss an object or location's dimensions, you're referring to its size and proportions.
Dimensions are just the different aspects of what we perceive to be reality.
We are acutely aware of the three dimensions that surround us on a daily basis: the length, width, and depth of all items in our universes, as well as the one dimension of time.
But here's the prospect that there are many more dimensions out there. According to string theory, one of the most influential physics theories of the last half-century, the universe has ten dimensions.

The graph shows the location of point P and point R. Point R is on the y-axis and has the same y-coordinate as point P. Point Q is graphed at (n,-2). The distance from point P to point Q is equal to the distance from point P to point R. What is the from point P to point Q? What is the value of N? Explain how you determined the distance from point P to point Q, and the value of N.
Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =
[tex] \sqrt{ {( n - n}) ^{2} + {( 3- ( - 2) })^{2} } [/tex]
[tex] = > \sqrt{ {(3 + 2)}^{2} } = \sqrt{ {5}^{2} } = 5[/tex]
Distance between P & R =
[tex] \sqrt{ {(n - 0)}^{2} + {(3 - 3)}^{2} } [/tex]
[tex] = > \sqrt{ {n}^{2} } = n[/tex]
But in question it is given that distance between P & Q is equal to the distance between P & R. So,

Luke rides his bike to his aunt's house. He travels 10 mi/h. Because it starts to rain, Luke's aunt drives him home in a car traveling at 25 mi/h. It takes Luke 1.5 h longer to get to his aunt's house than to return home. How many hours did it take Luke to ride to his aunt's house?
Answer:
2.5 hours
Step-by-step explanation:
Let t = time in hours for reach friend's house
(t-1.5) = time for friend to drive her home
:
Both trips are the same distance, Write a distance equation from this fact:
Distance = speed * time
Drive distance = Bike distance
Equation-
step1) 25 (t-1.5) = 10t (here u multiply 25 by t and 25 by 1.5)
step2) 25t - 37.5 = 10t (move 37.5)
step3) 25t - 10t = +37.5 (subtract 25t from 10t)
step4) 15t = 37.5 (divide 37.5 by 15)
step5) t = 2.5 (time it took Luke to reach his aunt's house)
a student earned a grade of 80% on a math test that had 20 problems how many problems on this test did the student answer correctly
Answer:
16
Step-by-step explanation:
To find 80% of 20, multiply .80 x 20
.80×20 = 16
This is how you multiply percentages--put the decimal point 2 places to the left, then multiply. In this case, you're looking at 80%, so move the decimal point two places to the left
80.0 becomes .80
Then multiply that by the number you're trying to find the percentage of

Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]V=\sqrt[3]{x-1}+3[/tex]
Determining the domain:
We know that the domain of a function is the set of input values for which the function is defined.
From the given graph, it is clear that the function has no undefined points nor domain constraints.
Therefore, the domain is:
{x | x is a real number}In other words:
[tex]\mathrm{Domain\:of\:}\:\sqrt[3]{x-1}+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Determining the range:
We know that the range of a function is the set of values of the dependent variable for which a function is defined.
It is clear from the graph that the range can be any real number.
i.e. the range is:
{y|y is a real number}
In other words,
[tex]\mathrm{Range\:of\:}\sqrt[3]{x-1}+3:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function is translated horizontally to the left. the base function is [tex]y = \sqrt{x}[/tex].
A. f(x) [tex]\sqrt{(x-5)} + 1[/tex], the graph should be translated horizontally 5 units to the right.
It's not the case and the translated 1 unit vertically.
B. [tex]f(x) = \sqrt{(x-2)}[/tex] the graph should be translated horizontally 2 units to the right. It's not the case.
C. [tex]y = \sqrt{x}[/tex], the graph should start at x=0. It's not the case.
D. [tex]f(x) = \sqrt{(x+4)}[/tex], the function is translated 4 times horizontally to the left. So this is the case.
Therefore, the function graphed is option D. [tex]f(x) = \sqrt{(x+4)}[/tex], the function is translated 4 times horizontally to the left.
