What is an equation of the line that passes through the point
(−4,−6) and is perpendicular to the line 2x−y=6?
Step-by-step explanation:
The slope of the given line is 2
The negative reciprocal of it is -½
y--6=-½(x--4)
y+6=-½(x+4)
2y+12=-x-4
2y=-x-4-12
2y=-x-16
y=-½x-8
Answer:
Step-by-step explanation:
-y = -2x + 6
y = 2x - 6
perp. -1/2
y + 6 = -1/2(x + 4)
y + 6 = -1/2x - 2
y = -1/2x - 8

Find the perimeter of the above shape to the nearest whole number take pi as 22/7
The unshown part is 16cm
Answer:
60.
Step-by-step explanation:
I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.
So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.
(14*2) + (16*2) =
28 + 32 = 60.
Which expression represents (−21−−−−√5)6 in rational exponent form? (−21)6/5 −215/6 (65)−21 (56)−21
Answer:
[tex](-21)^\frac{6}{5}[/tex]
Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]
The question is in the screenshot.

you just subtract it and convert it to percentBryan spent 14 minutes on the phone while routing 7 phone calls. How many phone cells does Bryan have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side
Answer:
[tex]x=9, AB=BC=AC=35[/tex]
Step-by-step explanation:
Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for
[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)
Solving for [tex]x[/tex], we get:
[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)
[tex]2x=6x-36[/tex] (Simplify)
[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]-4x=-36[/tex] (Simplify)
[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=9[/tex] (Simplify)
Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 40 N acts on a certain object, the acceleration
of the object is 10 m/s. If the acceleration of the object becomes 6 m/s?, what is the force?
Answer:
New force = 24 N
Step-by-step explanation:
The force acting on the object varies directly with the object's acceleration
i.e.
[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex] ...(1)
We have,
F₁ = 40 N, a₁ = 10 m/s², a₂ = 6 m/s₂, F₂ =?
Put all the values in equation (1).
[tex]F_2=\dfrac{F_1a_2}{a_1}\\\\F_2=\dfrac{40\times 6}{10}\\\\F_2=24\ N[/tex]
So, the new force becomes 24 N.

The point (0, 5) is the midpoint between (-18, -10) and what other point?
A. (18, 20)
B. (18, 15)
C. (20, 18)
D. (20, 20)
Answer:
The coordinates of the other point are:
(x₂, y₂) = (18, 20)
Hence, option A is correct.
Step-by-step explanation:
Given
The midpoint (x, y) = (0, 5)The first point (x₁, y₁) = (-18, -10)To determine
The second point (x₂, y₂) = ?Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)
[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
Here:
(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)
substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula
[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]
equating
[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]
[tex]x_2-18=0[/tex]
Add 18 to both sides
[tex]x_2-18+18=0+18[/tex]
[tex]x_2=18[/tex]
also
[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]
[tex]10=y_2+\left(-10\right)[/tex]
[tex]10=y_2-10[/tex]
[tex]10+10=y_2[/tex]
[tex]10+10=y_2[/tex]
[tex]y_2=20[/tex]
Therefore, the coordinates of the other point are:
(x₂, y₂) = (18, 20)
Hence, option A is correct.
Answer:
(x₂, y₂) = (18, 20)

Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4
Write an equation of the perpendicular bisector of the segment with the endpoints (8,10) and ( -4,2).
y =
Answer:
The required equation is:
[tex]y = -\frac{3}{2}x+9[/tex]
Step-by-step explanation:
To find the equation of a line, the slope and y-intercept is required.
The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.
Given points are:
[tex](x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)[/tex]
We will find the slope of given line segment first
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}[/tex]
Let m_1 be the slope of perpendicular bisector then,
[tex]m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}[/tex]
Now the mid-point
[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)[/tex]
We have to find equation of a line with slope -3/2 passing through (2,6)
The equation of line in slope-intercept form is given by:
[tex]y = m_1x+b[/tex]
Putting the value of slope
[tex]y= -\frac{3}{2}x+b[/tex]
Putting the point (2,6) to find the y-intercept
[tex]6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9[/tex]
The equation is:
[tex]y = -\frac{3}{2}x+9[/tex]
The equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is [tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex] and this can be determined by using the point-slope form of the line.
Given :
Endpoints -- (8,10) and (-4,2)
The following steps can be used in order to determine the equation of the perpendicular bisector:
Step 1 - First, determine the slope of the line that passes through points (8,10) and (-4,2).
[tex]\rm m =\dfrac{2-10}{-4-8}[/tex]
[tex]\rm m = \dfrac{8}{12}[/tex]
[tex]\rm m = \dfrac{2}{3}[/tex]
Step 2 - So, the slope of the perpendicular bisector is given by:
[tex]\rm m'm = -1[/tex]
[tex]\rm m' = -\dfrac{3}{2}[/tex]
Step 3 - Now, determine the midpoint of the line that passes through the points (8,10) and (-4,2).
[tex]\rm x = \dfrac{8-4}{2}=2[/tex]
[tex]\rm y = \dfrac{10+2}{2}=6[/tex]
Step 4 - So, the equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is:
[tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex]
