Find k so that the line through(k-1,k+2) and (4,-1) is perpendicular to the line through (-3,2) and (2,5).
Answer:
k = 2
Step-by-step explanation:
Perpendicular lines have slopes opposite reciprocalFormula to find a slope:
m = (y₂-y₁)/(x₂-x₁)Coordinates of the first line:
(k-1, k+2) and (4, -1)Coordinates of the second line:
(-3, 2) and (2, 5)Slopes of the lines:
m₁ = (-1 - k -2)/(4 - k + 1) = - (k + 3)/-(k -5) = (k + 3)/ (k - 5)m₂ = (5 - 2)/ (2 + 3) = 3/5Since m₁ = - 1/m₂, we have:
(k + 3)/ (k - 5) = - 5/33(k + 3) = -5(k - 5)3k + 9 = - 5k + 253k + 5k = 25 - 98k = 16k = 2So the answer is 2

Determine the slope of a line containing the points
C (1,8) and D (3, 3). Write your answer in the form of a
fraction.
Answer:
The answer is
[tex] - \frac{5}{2} [/tex]Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{y _{2} -y _{1}}{x _{2} - x _{1}} [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
C (1,8) and D (3, 3)
The slope is
[tex]m = \frac{3 - 8}{3 - 1} = \frac{ - 5}{2} [/tex]We have the final answer as
[tex] - \frac{5}{2} [/tex]Hope this helps you

Two angles are supplementary and have equal measures. What must
the measure of each angle be?
Answer:
These angles are called angle pairs. ... Supplementary angles are two angles whose sum is equal to \begin{align*}180^\circ\end{align*}. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.

Vertical Angles
Step-by-step explanation:
Vertical Angles are the angles opposite each other when two lines cross.
It is found that angle 2 and angle 1 are vertically opposite angles.
What is vertically opposite angles?The vertically opposite angles are those angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
Thus, Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
Also, When you slice a given object vertically (perpendicular to the ground level), then the sliced surface is called vertical cross section.
WE have to Classity 2 and 1 using all relationships that apply.
Therefore, we can see that angle 2 and angle 1 are vertically opposite angles.

Find the distance between each pair of points (-6,-10) , (-2,-10)
Answer:
4 units
Step-by-step explanation:
Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex], where (x1, y1) and
(x2, y2) are 2 points
Plug in the points given
d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
d = [tex]\sqrt{(-6 + 2)^2 + (-10 + 10)^2}[/tex]
d = [tex]\sqrt{(-4)^2 + (0)^2}[/tex]
d = [tex]\sqrt{16 + 0}[/tex]
d = [tex]\sqrt{16}[/tex]
d = 4
So, the distance between the points is 4 units
The distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
The points are (-6,-10) , (-2,-10)
Using distance formula:
[tex]\rm d=\sqrt{(-2-(-6))^2+(-10-(-10))^2}[/tex]
d = √16
d = 4 units
Thus, the distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.

Any number to the power of zero is always?
Answer:
In short, the multiplicative identity is the number 1, because for any other number x, 1*x = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity,
Answer: Any number to the power of zero would be 1

Find the value of x in each case:
Answer:
2x = 36°
8x = 144°
Step-by-step explanation:
8x + 2x = 180°
10x = 180°
x = 180/10
x = 18
then:
2x = 2*18 = 36°
8x = 18*8 = 144°
The value of x from the given diagram is 18. then each angle will be 2x = 36° and 8x = 144°
What is linear equation?Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c
Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.
Also, the triangle ACD, the sum of the interior angle of the triangle is 180 degrees;
8x + 2x = 180°
10x = 180°
x = 180/10
x = 18
Then:
2x = 2*18 = 36°
8x = 18*8 = 144°
Hence the value of x from the given diagram is 18.

The length of a square garden is twice a number. If the perimeter of the garden is 36, find the number.
Answer:
x = 4.5
Step-by-step explanation:
l = 2x
p = 4l
note: 4l in this case because it is a square
plug in l into equation p
36 = 4(2x)
36 = 8x

x = 4.5
P + 4 Solve for p
--------- = 5
6
Answer:
p = 26
Step-by-step explanation:
(p+4)/6 = 5
Multiply each side by 6
(p+4)/6 *6 = 5*6
p+4 = 30
Subtract 4 from each side
p+4-4 = 30-4
