Which equation represents a line which is perpendicular to the line y = 4/3x -7

A)3x + 4y = 8

B)4x – 3y = 24

C)4x + 3y = -6

D)4y - 3x = 12

Answers

Answer 1

Answer:

A)3x + 4y = 8

Step-by-step explanation:

Given expression;

          y = [tex]\frac{4}{3} x[/tex]   - 7

A line perpendicular to this will have negative inverse slope;

  the slope of the given line = [tex]\frac{4}{3}[/tex]

  perpendicular line  = [tex]-\frac{3}{4}[/tex]  

 Now;

      the equation of the line is;

 

           y =  [tex]-\frac{3}{4}[/tex] x  - 7

  multiply through by 4

          4y  = -3x - 28

          4y + 3x  = -28

Solve 1=4|x-2|+2


Help please

Answers

Answer:

No solution

Step-by-step explanation:

1=4|x-2|+2

-4|x-2| + 1 = 2

-4|x-2| = 1

False for every value of x

Since absolute value gives only a positive value, the -4 would always make that number negative which doesn't work

The closure properties of polynomials are similar to other closure properties. Which closure properties are similar to the closure properties of polynomials?

Answers

Answer:

The closure property of integers

Step-by-step explanation:

The addition closure properties of integers are similar

The closure property when adding integers are similar

It is similar because, when we add two polynomials, we get another polynomial

Also, when we add two integers, we get another integer

So we can conclude that the closure property of adding integers is similar

Tannis's first machine could throw a car 272727 meters. She studied her first machine and built a better one. Her second machine could throw a car 777 times as far.
How far does the second machine throw a car?

Answers

Answer:

The rate of change of the distance between the cars at that instant is 5.46 meters per second

Step-by-step explanation:

Speed of first car = 7 m/s

Speed of second car = 3 m/s

At instant, distance of first car from intersection = 5 meters

distance of second car from intersection = 12 meters

Therefore, we have

Distance between both cars at intant = √(12² + 5²) = 13 m

Rate of change of distance is given by;

2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt

= 26dd/dt = 2×5×7 + 2×12×3 = 142

dd/dt = 142/26 = 5.46 m/s.

That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.

m = - ( 4 + m ) + 2

m - 2 = - ( 4 + m )

m - 2 = - 4 - m

The graph below shows the cost of pens based on the number of pens in a pack. What would be the cost of one pen?

$0.57
$1.75
$5.50
$6.50​

Answers

Answer:

$1.75

Step-by-step explanation:

Honestly, you don't really have to pay attention to the other numbers or ratios on the graph until you think you found your answer. Pay attention to whichever ratio you choose and follow these steps:

1. Identify which number is the cost and which is the amount of pens bought

2. Set it up as a division problem by using the cost and the dividend and the amount of pens as the divisor

3. After you have your answer, plot your ratio of 1:(your product) and if the line that was graphed is straight, you are correct.
