Answer:
yes there is a linear correlation
reason : a increase of 1 hour results in an increase of 3 height
y= 3x + 4
it has a positive slope of 3 ,and y intercept of 4
Step-by-step explanation:
Answer:
the area is the triangle is 37.5
Step-by-step explanation:
area = 1/2 base*height
Answer:
2x+7/6
Step-by-step explanation:
an normal function would be mapping x to y, since this is the inverse we would map y to x
f(x) and y are the same so I will take f(x) as "y"
1)3x-7/2=y
3y-7/2=x
solve/isolate "y" in 3y-7/2=x to get the value of "y"
3y-7/2=x
add "7/2" to both sides
3y-7/2+7/2=x+7/2
3y=x+7/2
divide both sides by "3"
3y/3=x/3+7/2/3
simplify:
y=2x+7/6
hope this helps!
The constant of proportionality of the given graph is gotten as 4.
<h3>How to find the constant of proportionality?</h3>
The constant of proportionality here is simply the slope of the graph.
Now, we will take two points and use their coordinates to find the slope from the formula;
m = (y2 - y1)/(x2 - x1)
Let us pick 2 points which are;
(1, 4) and (2, 8). Thus;
m = (8 - 4)/(2 - 1)
m = 4/1
m = 4
Thus, the constant of proportionality of the graph is gotten as 4.

Answer:
<h3>A, B and C.</h3>
Step-by-step explanation:
In mathematics, a function is defined a relation between two sets, where the input set is called domain and the output set is called range.
A function has a specific rule to be defined as such. An input cannot have to different outputs. In term of diagrams, an element of the input cannot be related (with the arrow) to two different outputs values.
As you can observe in the image, relation D doesn't represents a function, because one input element relates with two output elements.
Therefore, A, B and C represent functions, because they follow the definition of function.
