The equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.
How to find the equation of point slope form?A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).
given that
the coordinates points are (4, 6) and (10, 30)
(x1,y1) = (4,6)
(x2, y2) = (10,30)
The formula of point-slope is
(y - y1) = m(x - x1)
Here,
x1 = 4 and y1 = 6 but we don't know the value of
m.
now,find the value of m using the following formula
[tex] m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]
now, substitute the values, we get
[tex]m = \frac{(30 - 6)}{(10 - 4)}[/tex]
[tex]m = \frac{24}{6}[/tex]
m = 4
so, the value of m is 4.
substitute these values into the point-slope formula
(y - 6) = 4(x - 4)
y-6 = 4x - 16
y = 4x -16 + 6
y = 4x - 10
-4x + y + 10 =0
Hence, the equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.

Phoebe is reading a novel for her monthly book club. the novel is 368 pages long. so far, she has read 53 pages. phoebe plans to read 35 pages a day. write an equation that represented, the number of days it will take phoebe to finish the novel
The equation that represent the number of days it will take phoebe to finish the novel is: x= number of pages left to be read / pages to be read per day
Information about the problem:
novel’s pages = 368read pages = 53pages to be read per day = 35 pages/daynumber of days it will take phoebe to finish the novel = x ?To solve this problem, we have to write the equation in order to calculate (x) the number of days it will take phoebe to finish the novel with the given information:
number of pages left to be read = novel’s pages - read pages
number of pages left to be read = 368 – 53
number of pages left to be read = 315 pages
Knowing the number of pages left to be read we can write the following equation:
x = number of pages left to be read / pages to be read per day
x = 315 pages /35 pages/day
x = 9 days

Write an equation of each line.slope =3 ; through (1,5)
The equation of the line in point-slope form, with slope equal to 3 and passing through the point located at (1 , 5), is (y - 5) = 3(x - 1).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)
where m = 3 and (x1 , y1) = (1 , 5)
(y - 5) = 3(x - 1)
In slope-intercept form, the equation of the line is:
(y - 5) = 3(x - 1)
y - 5 = 3x - 3
y = 3x + 2
In standard form, the equation of the line is:
y = 3x + 2
3x - y = -2

In this question,
Blake is setting up his tent at a renaissance fair.
The tent is 8 feet tall, and the tether can be staked no more than two feet from the tent.
The stake, height and tether length of the tent form a right angle triangle where the tether length is the hypotenuse.
Applying Pythagoras theorem:
length² = height² + (stake distance)²
length = √(8² + 2²)
length = 8.5 feet
Therefore, the tether should be 8.5 feet long

Vertical Angle Theorem
30=6x
5=x
Answer:
x=5
Step-by-step explanation:
Hello! No worries, Geometry is very confusing.
There are several proofs and theorems to use when trying to prove an angle size. In this picture, we see two lines intersecting, forming an intersection point with two similar looking angles.
With the Vertical Angles Theorem, it explains that when two lines intersect such as shown here, the angle on the vertical side of the original angle are both equal to the same number and is identical. Similarly, using this theorem we know that the unnamed angles (the big ones) are identical too, as they are vertical sides of each other.
Now we know the angle 6x and 30 degrees are equal to each other. So how do we solve x?
We can solve for x by making it equal to each other, signaling that you understand the Vertical Angle Theorem and stating that those two angles are equal to each other.
6x=30 Divide by 6 both sides to isolate the x varianle
x=5
Therefore, x is equal to 5.

An eigenvalue of a is =2 find a basis for the corresponding eigenspace. what is the dimension of this eigenspace?
Applying induction to the size of the matrix, we can demonstrate that the eigenvalues of Ak are k for every positive integer k if A is a square matrix with eigenvalues. In light of this, A2's eigenvalues are exactly 2. (the squares of the eigenvalues of A).
What is an eigenvalue ?When a linear transformation is applied to a nonzero vector in linear algebra, the vector's eigenvector, also known as its characteristic vector, changes by a maximum scalar amount. The eigenvector is scaled by the associated eigenvalue, which is frequently represented by the symbol λ.

Step-by-step explanation:
Rules for expressions with fractions:
Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.
Mixed numerals (mixed numbers or fractions) keep one space between the integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.

Suppose you have an outdoor pool measuring 25 ft by 10ft . You want to add a cement walkway around the pool. If the walkway will be 1 ft thick and you have 304 ft³ of cement, how wide should the walkway be?
The area covered by the pool and the cement walkway is 304 square feet. The width of the walkway would be 5 feet
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Let x be represent the width of the walkway.
The pool measures 25 ft by 10ft . If the walkway must have a uniform width around the entire pool, then the total length of the pool and the walkway = 25+ x + x = 25 + 2x
The total width of the pool and the walkway = 10 + x + x = 10 + 2x
The area covered by the pool and the cement walkway is 304 square feet. This means that;
(25 + 2x)(10 + 2x) = 304
250 + 50x + 20x + 4x^2 = 304
4x^2 + 70x + 250 - 304 = 0
4x^2 + 70x - 54 = 0
x(x + 20) - 5(x + 20) = 0
(x - 5)(x + 20) = 0
x = 5 or x = - 20
Thus The width cannot be negative.
Therefore, the width of the walkway is 5 feet.

3u+3v = 15 , -2u+3v = -5
By elimination, the solution of the system of equations, 3u + 3v = 15 and -2u + 3v = -5, is (u , v) = (4 , 1).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in u and v, a variable should be eliminated by adding/subtracting the two equations.
Subtracting the two equations will eliminate the variable v.
3u + 3v = 15 (equation 1)
-2u + 3v = -5 (equation 2)
5u = 20
u = 4
Substitute the value of u to any of the two equations and solve for v.
3u + 3v = 15 (equation 1)
3(4) + 3v = 15
3v = 15 -12
3v = 3
v = 1
Hence, the solution of the system of equations is (u , v) = (4 , 1).

Answer:
Please give brainliest if it applies!
w = 20m
l = 60m
Step-by-step explanation:
P = 2l + 2w
We know the perimeter = 160 and we know that l = 3w, so write what we know and solve for w.
P = 2l x 2w
160 = 2(3w) + 2w
160 = 6w + 2w
160 = 8w
Divide both sides by 8
20 = w
Now we can figure out the length, which is 3(w) or 3 x 20 = 60
