Answer:
15y
Step-by-step explanation:
first the 2 can cancel:

turns into:

now since we need to find x-y,
x=16y
16y-y=15y
I might come back to this because I'm not 100% sure this is the answer you are looking for. Let me know if you have any questions.
Answer:
slope: (y₂ - y₁) / (x₂ - x₁)
(5 - 2) / (-1 - 1) = 3/-2 = -3/2
y = -3/2x + b
5 = -3/2(-1) + b
5 = 3/2 + b
b = 3.5
y = -3/2x - 7/2
(5.83 - 1.42) / (4.22 + 0.72) = 4.41/4.94
y = 4.41/4.94x + b
5.83 = (4.41/4.94)(4.22) + b
5.83 = 3.76724696 + b
b = 2.06275304
y = 4.41/4.94x + 2.06
(the numbers are really wacky so i hope thats right, so sorry if it isn't)
Answer:
3x+4y+7=0.... equations (1)
which is required equations
Answer:
5.05*10³
Step-by-step explanation:
-
<em>Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.</em>
- 5050 = 5.05 *1000 = 5.05*10³
None of them have a solution of x, but 5x=15, 7x-2=19, and 5x+6=21 all have the same answer of x=3
