Answer:
35
Step-by-step explanation:
Lines are described by equations of the form y = mx + b
The fast way of finding 'b' is to look for a place where x = 0 and plug in the x and y values into this equation. In the case of this line, when x = 0, y = 5:
5 = m(0) + b
5 = 0 + b
5 = b
To get the slope, 'm', we need to pick two points and divide the difference of their y values by the difference of their x values. Pick points where the line falls on the grid. The one we just used, (0,5), works well. So does (2,1).
Plug into the equation m = (y2-y1)/(x2-x1) to get m = (1-5)/(2-0) = -4/2 = -2
Our equation is y = -2x + 5
So take 112 and multiply it by 7, 7x112 = 784.
Answer:
Not all relationships are functions, but all functions are also relationships
Step-by-step explanation:
A relationship is a correspondence between two sets of values.
A relationship assigns values from an output set called range to a set and input called a domain.
On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).
In other words, if an input value
is assigned two or more output values
,
,
.. then the relationship is not a function. This means that <em>not all relationships are functions</em>.
is a relation but it is not a function.
because when x = 4 then y = 1 and y = 5.
Not all relationships are functions, but all functions are also relationships
