Answer:
Table 3
Step-by-step explanation:
In a proportional relationship there must be a constant rate of change.
The first table:
6-5 / 9-7 = 1/2
5-3 / 7-4 = 2/3
These are not equal so it is not proportional.
The second table:
10-8 / 150-120 =2/30
8-5 / 120-75 = 3/45
These are not equal so it is not proportional
The third table:
10-8 / 12-10 =2/2 = 1
8-6 / 10-8 =2/2 = 1
These are equal so this table is proportional.
A.) is your answer
this is because it is the only table with the pair of (0,0) This means it passes through the origin, and if it passes through the origin it is proportional, if it doesn't it isn't proportional
D.) is also your answer
This is because the equation of this line is y = 4x since there is no "B" this means it is proportional
Answer:
<u>A</u><u>.</u><u> </u><u>Rational</u>
Step-by-step explanation:
Any number that can be expressed as a fraction with denominator of 1, it is rational.
Since 45 can be expressed as
![= \frac{45}{1} \\](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B45%7D%7B1%7D%20%20%5C%5C%20)
It is rational
The radius is 3
center is (-3,3)
Step-by-step explanation:
start at (0,0) go left 3 then up 3 put a point there. Then from that point go up, left, right, and down 3. It should be a circle.
Kim =x
jordan=x+7
jodran age (x+7) times 4 =200
Kims age is 4(x+7)=200 -because x is kims age and you can solve for it here
kim is - by solving for x
x+7=200/4
x+7=50
x=43
Jordan is x+7 years old so
43+7
=50
