12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y= 555
y=15
Substitute y= 15 into

Which relation is a function?
{(8, –5), (–5, 8), (–5, –8), (–8, 5)}
{(2, –3), (–3, 2), (2, 3), (–2, 3)}
{(–7, 6), (6, –7), (–7, 9), (10, 3)}
{(5, –4), (–4, 5), (–5, 4), (4, –5)}
Answers
Answer:
the last one
Step-by-step explanation:
when looking for the function we have to know that none of the x values can repeat
in the first one the x value -5 repeats twice so that cannot be the answer
in the second one the x value 2 repeats twice so that cant be the answer
in the third one the x value -7 repeats twice so that also cannot be the answer
in the last one each x value has a different y value or every input has a different output therefore this one is the right answer
hope this helps :D
The relation that is a function is: {(5, –4), (–4, 5), (–5, 4), (4, –5)}.
A relation is a function if each input (x-value) is associated with only one output (y-value).
Let's analyze each relation:
1. {(8, –5), (–5, 8), (–5, –8), (–8, 5)} - This relation is not a function because the input -5 is associated with two different outputs (8 and -8).
2. {(2, –3), (–3, 2), (2, 3), (–2, 3)} - This relation is not a function because the input 2 is associated with two different outputs (-3 and 3).
3. {(–7, 6), (6, –7), (–7, 9), (10, 3)} - This relation is not a function because the input -7 is associated with two different outputs (6 and 9).
4. {(5, –4), (–4, 5), (–5, 4), (4, –5)} - This relation is a function because each input value is associated with only one output value. For example, 5 is associated with -4, -4 is associated with 5, -5 is associated with 4, and 4 is associated with -5.
Therefore, the relation that is a function is: {(5, –4), (–4, 5), (–5, 4), (4, –5)}.

which is the graph of y=3/4x -3
Answers
Answer:
A
Step-by-step explanation:
the formula y = mx + b is used here
lets look at the formula we were given
y = 3/4x -3
the first number we see, 3/4x is the slope of the line, where 1 = a 45 degree angle towards the NORTH EAST corner from 0, in this case it is less then 1 so it is less steep then 45 degrees, how i remember is that i can plot a point using the numbers the the fraction in reverse and connect a line from 0,0 to that line
4,3 is a point that a line with this slope would cross, but not this line, because it does NOT start at 0,0 , instead it crosses the y-axis lower because we took some of b away, in this case -3, so the line moves down 3, not changing the slope
i hope this makes sence and you are able to use it in multiple problems like this, comment this if you have any questions

find the solution for the system of linear equations by elimination: 2x+y=9,3x-y=16
Answers
Answer:
(-5,-1)
Step-by-step explanation:
2x+y=9 -> y=-2x+9
3x-y=16
3x-(-2x+9)=16
3x+2x-9=16
5x-9=16
5x-9 (+9)=16 (+9)
5x=25
x=5
no plug in 5 to x in any equation above
2(5)+y=9
10+y (-10)=9 (-10)
y=-1
so the answer is (-5,-1)
