What is the equation of the line that passes through the point ( -1, 1) and is perpendicular to 2x + 4y = 16?
A. y = −2x − 1
B. y − 3 = 2x
C. y = 6x + 7
D. Cannot be determined

Answers

Answer 1

Answer:

B

Step-by-step explanation:

We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:

[tex]2x +4y=16[/tex]

Remember that the slopes of perpendicular lines are negative reciprocals of each other.

So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:

[tex]4y=-2x+16[/tex]

Therefore:

[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]

The slope is -1/2.

The negative reciprocal of -1/2 is 2.

Thus, the slope of our new line is 2.

The slope is 2 and it passes through the point (-1, 1).

We can use the point-slope form:

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

Substitute:

[tex]y-(1)=2(x-(-1))[/tex]

Distribute:

[tex]y-1=2x+2[/tex]

Subtracting 2 from both sides yields:

[tex]y-3=2x[/tex]

Therefore, our answer is B.

Answers

Combine like terms.


7g + 4g + 3g + g = 15g

15g - 13g = 2g


2g = 10


Divide by 2 on both sides.


g = 5

Answer: g=5

Step-by-step explanation:

Given

7g+4g+3g-13g+g=10

Combine like terms

2g=10

Divide 2 on both sides

2g/2=10/2

g=5

is palpatine the strongest sith

Answers

Answer:

One may think that he is the most powerful Sith Lord, and on some levels this is correct, but that title falls to another, even more powerful Sith Lord. That is Jar Jar Binks. He possesses the power to wipe out entire universes without blinking an eye. Jar Jar is an entity that was here before the universe was created. He made God. He even made Shaggy in his image so that he could have a set of eyes on Earth. He needed a right hand man to corrupt humanity at its source. Some might say that Jar Jar is the true form of evil, but I refute that claim with an argument of my own. Jar Jar Binks may have destroyed countless lives, but he did so in order to keep the balance of the universe, and for that, I thank him. All hail Jar Jar.

Four friends shopped at the Sale Depot for movies. Robby went on Monday and bought three movies for $15.36. Paula went on Wednesday and bought five movies for $27.40. Trey went on Thursday and bought four movies for $20.08. Madison went on Friday and bought six movies for $31.44.

Answers

Answer: See explanation

Step-by-step explanation:

You didn't say what you want to get but I'm guessing that you want to know who had the cheapest deal or the best deal.

Robby went on Monday and bought three movies for $15.36. The cost per movie will be:

= $15.36/3

= $5.12

Paula went on Wednesday and bought five movies for $27.40. The cost per movie will be:

= $27.40/5

= $5.48

Trey went on Thursday and bought four movies for $20.08. The cost per movie will be:

= $20.08/4

= $5.02

Madison went on Friday and bought six movies for $31.44. The cost per movie will be:

= $31.44/6

= $5.24

We can see that Trey had the best deal.

Step-by-step explanation:

Steps:

I will solve your system by substitution.

y=9x+34;y=16x−29

Step: Solvey=9x+34for y:

Step: Substitute9x+34foryiny=16x−29:

y=16x−29

9x+34=16x−29

9x+34+−16x=16x−29+−16x(Add -16x to both sides)

−7x+34=−29

−7x+34+−34=−29+−34(Add -34 to both sides)

−7x=−63

−7x

−7

(Divide both sides by -7)

x=9

Step: Substitute9forxiny=9x+34:

y=9x+34

y=(9)(9)+34

y=115(Simplify both sides of the equation)

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

In the question, 3 functions in tabulated form is given, we draw the function on the graph then we observe that,

Table A, shows the cubic function because the graph with an increase of x  increase and decrease multiple times.

Table B, shows the quadratic function, is shows the curve as of the parabola.

Table C, shows the linear relationship, as it forms a line on the graph.

Slope= -65

y intercept = 1000

and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away

Step-by-step explanation:

Just graph these points which you can get by plugging in the numbers

1000-65= 935

(1,935)

1000-65*2=870

(2,870)

1000-65*3= 805

find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.

Answers

Answer:

13.5 cm

Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

L/θ = C/2π (C = Circumference = 2πr)

L/θ = 2πr/2π,

L/θ = r,

L = r*θ = 9 cm * 1.5 = 13.5 cm

Step-by-step explanation:

i.

25% = 0.25

0.25 = 25/100

25/100 (GCF 25) = 1/4

ii.

43.2% = 0.432

0.432 = 432/1000

432/1000 (GCF 8) = 54/125

iii.

0.02214% = 0.0002214

0.0002214 = 2214/10000000

2214/10000000 (GCF 2) = 1157/5000000
