Perpendicular lines have slopes that are opposite signs and reciprocals.
Since the line y = -1/4x + 10 has a slope of -1/4, the slope of the perpendicular line will be + 4/1 or 4. So any line with a slope of 4 will be perpendicular to y = -1/4x + 10.
This means A and D will be your answers.

What is the area of the triangle?
The total area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the base times the height, or A = 1/2 b x h. As a result, we need to know the triangular polygon's base (b) and height (h) in order to calculate its area.
From given figure we can see that WV is the height of the triangle and WU is the base.
W = (-3, 6), V = (-3, -8) and U = (0, 6).
To find the distance WV and WU by using the distance formula.
[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
So,
[tex]WV = \sqrt{(-3+3)^2 +(-8-6)^2} = \sqrt{(-14)^2} = 14\\ WU = \sqrt{((0+3)^2+(6-6)^2} = \sqrt{3^2} = 3[/tex]
Hence, the height is 14 units and the base is 3 units.
⇒
Area of triangle = 1/2 x base x height
= 1/2 x 3 x 14
Area of triangle = 21 units
Hence, the area of ΔUVW is 21 units.

m<A = 112.5
m<B = 67.5
m<C = 67.5
m<D = 112.5
Consider the provided information.
The sum of all interior angle of a polygon is: (n-2)*180
Substitute n = 8.
(8-2)*180 = 1080
Thus, the measure of each angle is:
∠B and ∠C are congruent and their sum is 135°
∠B+∠C=135°
∠B=67.5°
Hence, the m angle B and m angle C is 67.5°.
The sum of all angles of a quadrilateral is 360°.
∠A+∠D+∠B+∠C=360°
∠A+∠D=360°-135°
∠A+∠D=225°
∠A and ∠D are congruent and their sum is 225°
∠A+∠D=225°
∠A=∠D=112.5°
Hence, the m angle A and m angle D is 112.5°.

what is y in the solution for the system of equations x+5y=17 and 6x-5y=-3
The answer for the equation is x = 1 , y = 3.
Solve the following system: using elimination:
x + 5 y = 17 | (equation 1)
6 x - 5 y = -3 | (equation 2)
Swap equation 1 with equation 2:
6 x - 5 y = -3 (equation 1)
x + 5 y = 17 (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
6 x - 5 y = -3 (equation 1)
0 x+(20 y)/3 = 20 (equation 2)
Multiply equation 2 by 3/20:
{6 x - 5 y = -9 | (equation 1)
{0 x+y = 3 | (equation 2)
Add 5 × (equation 2) to equation 1:
6 x+0 y = 6 (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 6:
x+0 y = 1 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: x = 1 , y = 3
What is equation?There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math. A linear equation may have more than one variable.

Pythagorean Theorem On Coordinate Systems-Independent Worksheet
Find the distance between all the points listed below
Help me people please
Answer: The distance between the points (3, 4) and (0, 0) is 5.
Step-by-step explanation: The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem can be used to find the distance between two points in a coordinate system.
To find the distance between two points in a coordinate system, you can use the following steps:
Identify the coordinates of the two points.
Calculate the difference between the x-coordinates and the y-coordinates of the two points.
Use the Pythagorean Theorem to find the distance between the two points.
For example, to find the distance between the points (3, 4) and (0, 0), you would do the following:
Identify the coordinates of the two points: (3, 4) and (0, 0).
Calculate the difference between the x-coordinates and the y-coordinates of the two points: 3 - 0 = 3 for the x-coordinates and 4 - 0 = 4 for the y-coordinates.
Use the Pythagorean Theorem to find the distance between the two points: the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, so the distance between the points is equal to the square root of 3^2 + 4^2 = 9 + 16 = 25 = 5.
Therefore, the distance between the points (3, 4) and (0, 0) is 5.
Match each of the expressions to the right point.

ƒ”(x)=6x, f'(-3)=20, ƒ(-3)=-5
f(x)=?
Answer:
f(x) = x^3 - 7x + 1
Step-by-step explanation:
ƒ”(x)=6x ==> ƒ”(x)=6 * (x^1)
f'(x)=6/(1+1) * x^(1+1) + C ==> C is a constant that doesn't affect the derivative
f'(x)=6/2 * x^2 + C ==> simplify the first derivative
f'(x)=3 * x^2 + C ==> f'(x)=3(x^2) + C
f'(-3)=3((-3)^2) + C ==> plug in -3 into the derivative equation
f'(-3)=3(9) + C ==> simplify
20=3(9) + C ==> plug in 20 for f'(-3)
20=27+C
20-27=27-27+C ==> solve for C
C=-7
f'(x)=3(x^2) + (-7) ==> plug in -7 for C
f'(x)=3(x^2) - 7 ==> simplify
f(x) = 3/(2+1) * x^(2+1) - 7x + C
f(x) = 3/3 * x^3 - 7x + C
f(x) = x^3 - 7x + C
f(-3) = (-3)^3 - 7(-3) + C ==> plug in -3 into f(x)
f(-3) = -27 - (-21) + C
f(-3) = -27 + 21 + C ==> simplify
f(-3) = -6 + C
-5 = -6 + C ==> plug in -5 for f(-3)
-5 + 6 = -6 + 6 + C ==> solve for C
C = 1 ==> simplify
f(x) = x^3 - 7x + 1

Step-by-step explanation:
5x + 9y = 10
4x -3y = 8 If I multiple this second equation all the way through by 3, then the y's would cancel out when I add the equations together.
12x -9y = 24 multiplied the second equation through by 3
5x + 9y = 10 Add the 2 equations together
17x = 34 Divide both sides by 14
x = 2
Plug 2 in for x for either of the two original equations and solve for y
5x + 9y = 10
5(2) + 9y = 10
10 + 9y = 10 Subtract 10 from both sides
9y = 0 Divide both sides by 0
y = 0

What is multiplication of matrices?
The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

What is the largest possible product of two positive integers whose sum is 9?
Answer:
The largest possible product of two positive integers whose sum is 9 is achieved when the two integers are as far apart as possible, which occurs when one integer is the largest possible integer and the other is the smallest possible integer. The largest possible integer is the one that is closest to but less than 9, which is 8, and the smallest possible integer is 1. The product of 8 and 1 is 8, so the largest possible product of two positive integers whose sum is 9 is 8.
