What is the slope of the line? Pls help! I’ll mark the brainliest

Mathematics
1 answer:
VLD [36.1K]2 years ago
8 0

Answer:

m = -3

Step-by-step explanation:

Two poin on this line are (-2, 3) and (0, -3).  Both points are formed where grid lines meet precisely.

The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6.  Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

At what point on the curve y = 19 2x is the tangent line perpendicular to the line 20x 4y = 1?
Gennadij [26K]

The points are; (7/2, -1/2).

<h3>What is the given point?</h3>

Now the tangent line is given as;20x 4y = 1. When we rewrite it in the slope intercept form, we have the equation as; y = 1 - 20x/4 or y = 1/4 - 5x.

Then to obtain the slope of the curve we have; y = 19 - 2x

dy/dx = 2

Using the relation;

m1m2 = -1

m2 = -1/2

Hence;

y = 1/4 - 5(-1/2)

y = 1/4 + 5/2

y = 7/2

Thus the points are; (7/2, -1/2)

Andrea is designing the seating arrangement for a concert in her local park. The number of seats in row 20 would be 86 seats.

<h3>What is the Arithmetic Sequence?</h3>

Arithmetic sequence is a sequence where each consequtive term has a common constant difference.

An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term and the common difference.

The arithmetic sequence formula is;

aₙ = a + (n − 1)d,

where;

a is the first term

n is the position of the term in the sequence

d is the common difference

aₙ  is the nth term of the sequence.

Our sequence is 10, 14, 18, 22 up to row 20.

Using the sequence formula;

a_{20} = 10 + (20 - 1)4.\\a_{20} = 10 + (19\times 4)\\a_{20}= 10 + 76\\a_{20}= 86.

Thus, the number of seats in row 20 was 86 seats.

Can someone please help me with these?
Vikki [24]

Answer:

  Ⓒ  {1, 2, 3, 6, 9, 13, 14}

Step-by-step explanation:

One way to find the union of two sets is to list all the elements of both sets in order, then delete any duplicates.

Here, joining the two sets gives ...

  {1, 6, 2, 3, 14, 2, 9, 13, 1}

Putting these elements into numerical order, we have ...

  {1, 1, 2, 2, 3, 6, 9, 13, 14}

I have highlighted the duplicates. Deleting those gives us the desired union of the two sets:

  X ∪ Y = {1, 2, 3, 6, 9, 13, 14} . . . . . matches choice C

What is the solution of the equation 6x - 4 = 2(3x - 2). Explain your steps.​
Vikki [24]

Answer:<em><u> x= 4/3 but in decimal form =1.333</u></em>

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4-(2*(3*x-2))=0

4 -  2 • (3x - 2)  = 0

Pull out like factors :

  8 - 6x  =   -2 • (3x - 4)  

Solve  :    3x-4 = 0  

Add  4  to both sides of the equation :  

                     3x = 4

Divide both sides of the equation by 3:

                    <em><u>x = 4/3 = 1.333</u></em>
