Answer: square root 50 that does not belong
Step-by-step explanation:
X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8

let me know if it is correct
Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
Answer:
He did 2 divide by 2.50 instead of 2.50 divide by 2 like x and y y=kx
Step-by-step explanation:
2.50 ➗2 = 1.25 per pound
