The point (2, -3) lies in quadrant

Mathematics
1 answer:
timurjin [86]3 years ago

Answer:

Therefore,

( 2 , -3 ) Lies in Quadrant IV.

Step-by-step explanation:

Quadrant :

The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants.

Recall that the coordinate plane has an x-axis that divides into a top and bottom half, and a y-axis dividing into the left and right half. Together they create the four quadrants of the plane.

Numbering is done in Anticlockwise

Quadrant I  -          x-coordinate is Positive , y-coordinate is Positive.  

Quadrant II   -        x-coordinate is Negative , y-coordinate is Positive.  

Quadrant III    -      x-coordinate is Negative , y-coordinate is Negative.  

Quadrant IV     -    x-coordinate is Positive , y-coordinate is Negative.  

Therefore,

( 2 , -3 ) Lies in Quadrant IV.

Find the length of MN.<br> A) 7 <br> B) 25 <br> C) 32 <br> D) 39
MrRissso [65]

Step-by-step explanation:

Answer C)

Explanation:

MN + NP = MP

MP = 39

Therefore, 4(x + 5) + 2x + 1= MP

So, 4(x + 5) + 2x + 1= 39

(4x + 20) + 2x +1 = 39

So, (4x + 2x) + (20 + 1) = 39

6x + 21 = 39

Addition changes to Subtraction

So, 6x = 39 - 21

6x = 18

Multiplication changes to Division

x= 18/6

x=3

Therefore MN = 4(x + 5)

So, 4(3 + 5) = 4(8)

4(8) = 32

Therefore, MN = 32

Hope this helps!

melomori [17]
<u><em>Answer:</em></u>
c = 4

<u><em>Explanation:</em></u>
The number of solutions for any equation is equal to the degree of the equation.

The given equation is a second degree equation which means that it has two solutions.

The only possible way for it to have one unique real solution is that the two <u>solutions are equal</u>

<u>This means that:</u>
x - 4 = x - c
<u>Now, we solve for c:</u>
x - 4 - x = x - c - x
-4 = -c
c = 4

Hope this helps :)

Hey, guys help me answer!
Sliva [168]

Hello and Good Morning/Afternoon

<u>Let's take this problem step by step.</u>

        5=\frac{1}{3}(5x-15)\\ 5=\frac{5}{3}x-5\\ 5+5= \frac{5}{3}x-5 +5\\10=\frac{5}{3}x\\ 10 * 3 = 3* \frac{5}{3}x\\30=5x\\\frac{30}{5} =\frac{5}{5}x\\ 6=x\\x=6

<u>What did we do in this problem</u>

  • we ensured that both sides remained equally balanced in value
  • took everything step-by-step to make sure that there were no mistakes
  • to check it, we can plug it back into the original equation to see if it works

                  5=\frac{1}{3}(5(6)-15)\\ 5=\frac{1}{3} (30-15)\\5=\frac{1}{3}*15\\ 5=5 \checkmark\\

<u>Answer: x = 6</u>

Hope that helps!
