Answer:
All those canbe expressed in the form of p/q, where q≠0 are rational
clearly A is rational
now 0.62 =62/100=31/50----its also rational
and 0.6 =6/10=3/5--- it's also rational
0.6π =(3/5)π, 3/5 is rational but π is irrational so overall it's irrational!
A,B&C are rational!

I can't write the symbol, but it would be X<30 and the <would have a horizontal line under it so that it would mean x is less than or equal to 30
Answer:
Y=2x-1
Step-by-step explanation:
In order to find the slope, its rise over run. So you would move from (0,-1) to the next point it intercepts, (1,1) and find it from there
As for the Y-Intercept, it would just be wherever the line connects with the Y axis, which happens to be (0,-1) or Negative 1.
Answer:
y + 2 = -0.069(x-+5)
Step-by-step explanation:
SInce the two lines intersects, we will equate it
Multiply x + 3y = 0 by 4;
4x + 12y = 0
4x-4y-13 = 0,
Subtracts both
12y +4y + 13 = 0
16y = 13
y = 13/16
get x;
x + 3(13/16) = 0
x = -39/16
The point of intersection is (0.8, -2.4) and (-5,-2)
Get the equation;
m = y2-y1/x2-x1
m = -2+2.4/-5-0.8
m = 0.4/-5.8
m = -0.069
Get the equation;
y - y0 = m(x-x0)
y - (-2)= -0.069(x-(-5))
y + 2 = -0.069(x-+5)
