Line segment NY has endpoints N(-11, 5) and Y(3,-3).
What is the equation of the perpendicular bisector of Ny?

Answers

Given:

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

To find:

The equation of the perpendicular bisector of NY.

Solution:

Midpoint point of NY is

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-11+3}{2},\dfrac{5-3}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-8}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-4,1\right)[/tex]

Slope of lines NY is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-3-5}{3-(-11)}[/tex]

[tex]m=\dfrac{-8}{14}[/tex]

[tex]m=\dfrac{-4}{7}[/tex]

Product of slopes of two perpendicular lines is -1. So,

[tex]m_1\times \dfrac{-4}{7}=-1[/tex]

[tex]m_1=\dfrac{7}{4}[/tex]

The perpendicular bisector of NY passes through (-4,1) with slope [tex]\dfrac{7}{4}[/tex]. So, the equation of perpendicular bisector of NY is

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-1=\dfrac{7}{4}(x-(-4))[/tex]

[tex]y-1=\dfrac{7}{4}(x+4)[/tex]

[tex]y-1=\dfrac{7}{4}x+7[/tex]

Add 1 on both sides.

[tex]y=\dfrac{7}{4}x+8[/tex]

Therefore, the equation of perpendicular bisector of NY is [tex]y=\dfrac{7}{4}x+8[/tex].

Determine the equation of the line given by the graph.
A)y = -2/7x+2/5
B)y = -2/7x+5/2
C)y = -7/2x+2/5
D)y = -7/2x+5/2

Answers

Answer:

y=mx+c y= -2/7+5/2 if this is right can i get brainliest and if u need explanation just ask

Answer:

D. y = -7/2x+5/2

Step-by-step explanation:

The formula for the graph would be: y = mx + c where m is the slope and c is the y-intercept.

Based on the graph, you can see that the y-intercept is 5/2 (somewhere between 5 and 0) so A and C are out. Remaining are options B and C.

Now, the slope is either -2/7 or -7/2. We will have to calculate the slope then. I will be using the points (-1, 6) and (1, -1)

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-1-6}{1-(-1)}[/tex]

    = [tex]\frac{-7}{2}[/tex]

   = -[tex]\frac{7}{2}[/tex] (Same as option D)

Thus, the equation would have been: -[tex]\frac{7}{2}[/tex]x + [tex]\frac{5}{2}[/tex]

Which situation represents a proportional relationship?
А.
The cost of purchasing t-shirts for $5.80 each.
B
The cost of purchasing belts for $11.00 each with a delivery charge of $3.50.
С.
The cost of purchasing a box of socks for $1.75 per sock plus $2.15 for the box.
D
The cost of purchasing pants for $21.50 each with a coupon for $3.25 off the total cost.

Answers

Answer:

С.

Step-by-step explanation:

From the options provided the only one that represents a proportional relationship was The cost of purchasing a box of socks for $1.75 per sock plus $2.15 for the box. This is because the total cost of the boxes depends on the number of socks that are bought since every pair of socks that are bought comes with a box which causes the total costs of the boxes to increase. Therefore, the number of sock pairs and the number of boxes has a proportional relationship.

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

Answers

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

[tex]60\:\times 2^{-2}[/tex]

[tex]=60\times \frac{1}{2^2}[/tex]             ∵ [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]

[tex]=\frac{1\times \:60}{2^2}[/tex]

[tex]=\frac{60}{2^2}[/tex]

[tex]=\frac{2^2\times \:3\times \:5}{2^2}[/tex]

[tex]=3\times \:5[/tex]

[tex]=15[/tex] gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

There are 42 female performers in a dance recital. The ratio of men to women is 2:3. How many men are in the dance recital

Answers

28

Step-by-step explanation: This should be 28. 42 divided by 3 is 14. Why would you divide it by 3? Because the full ratio is 2:3. So 42 divided by 3 is 14. Then you add fourteen twice, for the two in the ratio. Fourteen plus fourteen is 28.

What was the value of b?
A. –6
B. –2
C. 2
D. 10

Answers

Answer: C. 2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Begin by removing the brackets

4x + 5(-4x - b) = -16x - 5b

-(x - 2) = -x + 2

Add the two binomials together to get the third one

4x -20x - 5b - x + 2 = -17x - 8                 Combine the like terms on both sides

-17x - 5b +2 = -17x - 8                             Add 17x to both sides

-5b + 2 = - 8                                           Subtract 2 from both sides

-5b +2 -2 =- 8 -2                                     Combine    

-5b =  - 10                                               Divide by -5

b = -10/-5

b = 2

The answer is -2x intercept 2,y-intercept:1 because the line is touching the graph where 2 is which identifies that it’s an x intercept and for the -2 it hit a point when the the line goes down to -2 and of course 1 is y because it shows the y on the top.
