How Do You Graph Order Pairs

Mathematics
1 answer:
kakasveta [241]3 years ago
3 0
Each "ordered pair" describes one point on the graph. It's a pair of numbers.

-- The first number is the 'x'-coordinate of the point ... it tells how far the point
is left or right of the center.

-- The second number is the 'y'-coordinate of the point ... it tells how far the
point is up or down from the center. 

-- With that much information, you can find any point on an infinite piece of
paper that has no ends.  You only need an ordered pair of numbers, and
you need to know where the center of left-right is, and where the center of
up-down is.  Those lines are always drawn on the graph before you start
marking your ordered pairs.

Is 9/10, 1 1/5, 1 1/2 a right triangle?
tankabanditka [31]

Answer:

using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2

a²+b²=c²

(9/10)²+(11/5)²=(11/2)²

81/100+121/25=121/4

lcm of 25 and 100 =100

(81+484)/100=121/4

565/100=121/4

113/20=121/4

since they are not equal therefore it's not a right angle triangle

URGENT PLEASE HELP!!!!!
telo118 [61]

(1)

we are given

\frac{y}{6} =x

we can  find for y

multiply both sides by 6

\frac{y}{6}*6 =6*x

y=6x

we can see that y is directly proportional to x

so, option-D........Answer

(2)

y varies inversely with x

so, we can write it as

y=k\frac{1}{x}

now, we are given

y=5 when x=2.5

so, we can plug it here

5=k\frac{1}{2.5}

and then we can solve for k

5*2.5=2.5*k\frac{1}{2.5}

k=12.5

now, we can plug back

y=\frac{12.5}{x}

we can plug x=20

y=\frac{12.5}{20}

y=0.625.............Answer

(3)

we are given

The current, I, in a circuit varies inversely with the resistance, R

so, we can write it as

I=\frac{k}{R}

we have R=12 when I=3

so, we can plug it

3=\frac{k}{12}

now, we can solve for k

3*12=12*\frac{k}{12}

k=36

now, we can plug back

I=\frac{36}{R}

we can plug R=6

I=\frac{36}{6}

I=6................Answer
