Is it supposed to say 7x rather than Z? If so then
If you make both equations = to 4y you can work out the answer so
4y =7x-4
4y = 36-3x
Then you put them equal to each other so
7x-4 = 36-3x
10x = 40
x = 4
You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6
So the answer is x = 4 and y = 6
To find the perimeter you just add up all the numbers on the sides
Area for a square is base times height
Area for a triangle is 1/2 base times height
Answer:
No
Step-by-step explanation:
Definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output
Here we have more than one output for one input:
- x=-1 => y= -1, 0, 1
- x= 1 => y= 1, 2, 3
So this is not a function
The answer is D. Quadrant I, as both the X and Y coordinates are positive.
