Answer:
y = -9
Step-by-step explanation:
divide by 5 first
y + 2 = -7
-2
y = -9
-3x-6y=17
-6y=3x+17
y=-x/2-17/6 so the slope of the line is -1/2
For another line to be perpendicular to this one the product of their slopes must equal -1
(-1/2)m=-1, m=2 so the perpendicular line will have a slope of 2...
y=2x+b, using point (6,3) we can solve for b...
3=2(6)+b
3=12+b
b=-9 so
y=2x-9
the equations
1/4=2x and 1/4/x=2have the same solution
because 1 / 4/ x = 2 can be simplified to
1 / 4 = 2x which is the same with the first equation
Solve for x = 1/8
Then substitute it to the both equation
¼ = 2 ( ¼)
¼ = ¼
2nd equation
1/ 4 /( 1/8) = 2
2 =2

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
