The you find this is by first finding the slope. You do this by finding the difference between both x values and then both y values. You get 12(x), 6(y) then write it as a fraction. it is 12/6 which simplifies to 2. 2 is our slope. then you write it out in slope intercept form (y=mx+b) and plug in your numbers. pick one set of original points an put them in to x and y. now you just solve for b. this gives you -9 as b. you put it together to get
y=2x-9
hope this helps!!!! :)
Basically the situation has to have two variables that have a correlation.
Weights of apples - one variable
Daily temperatures - one variable
Ice cream sales - one variable
Apple sales compared to the average temperature that day - Two variables because you have apple sales as a result of temperature.
answer: D
Given:
The scale factor between two circles is 
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles
Therefore, the correct option is D.
Answer:
Step-by-step explanation:
Add 5 to both sides of the equation.
y=1/16⋅(x−3)2+5
Simplify each term.
y=(x−3)^2/16+5
Use the vertex form, y=a(x−h)2+k, to determine the values of a, h, and k. a=1/16 h =3 k=5
Since the value of a is positive, the parabola opens up.
