Step-by-step explanation:
The graph crosses the y-axis at (0,-2).
The slope of the graph is 3.
y = 3x - 2
Answer:
6.74
Step-by-step explanation:
add all numbers and divide how many numbers there are.
Answer:
x = 84
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, thus
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540 for x
131 + 108 + 107 + 110 + x = 540, that is
456 + x = 540 ( subtract 456 from both sides )
x = 84
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
Yes, they can. Rational numbers are also decimals (for example) so we can put an infinite amount of numbers between any 2 values, for example:
1,1
1,11
1,111
1,1111
2
5,328
5,3281
5,3282
50
90,01
90,011
etc.
