Answer: B) Infinitely many solutions; both equations are equivalent
==============================================================
Work Shown:
x+y = 4 ... start with the first equation
x + (-x+4) = 4 ... replace y with (-x+4)
x-x+4 = 4
0x+4 = 4
0+4 = 4
4 = 4 ... this is a true statement regardless of what x you pick
So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.
Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.
Answer: A. (4, 4) and (4, 5)
Step-by-step explanation:
The same x value maps onto more than one y value.
Answer:
16
Step-by-step explanation:
because 7 times 4 is 28
4 times 4 is 16.
also it says 1/4 and yeah the little box is 1/4 of the big one so that is your answer <3 :]
You do 8* 7 = 56 + 7 = 63/8
You do 4*3 = 12 + 1 = 13/4
63/8 - 13/4 = 37/8
does this help
The answer is f(x) I’m not quite sure what
