Yes. There are 2 decimal places in .51 and 3 in 2.427.
So there would be a total of 5 decimal places.
Answer: 2/3
Step-by-step explanation:
3(y-1) = 2x + 2
Expand: 3y - 3 = 2x + 2
Isolate the y by adding 3 to both sides: 3y = 2x +5
Isolate the y by dividing 3 from both sides: y = 2/3x +5/3
Remember, in y = mx + b, m = slope.
So, 2/3 is the slope.
5(3)-(-3)
15- (-3)
15+3 = 18
Answer: the the 2nd circular one
Step-by-step explanation: Functions can't just go in a circle, they will repeat the x value
