Inverse is reflect across x=y line
switch and solve
y=3x-12
x=3y-12
x+12=3y
y=1/3x+4
the inverse is y=1/3x+4
Answer:
16 tiles is the answer..........
To figure out how many 8ths are in 48, you do 48/8=6
So 1/8 of 48 is 6
So to figure out 5/8 do
6*5=30
Hopefully this helps :D
To know while working with inequality equations:
- When multiplying or dividing by a negative, you want to flip the direction of the inequality sign. < becomes >, etc
- When graphing, if it is only less/greater than (< or >) the dot will be open
- When graphing, if it is less/greater than and equal too (≤ or ≥) the dot will be closed
- Then, if the x value is on the left side, the arrow will go in the direction of the inequality sign
[3] Divide both sides by -4, flip the sign
-4x ≥ -36
x ≤ 9
[4] Divide both sides by -0.4, flip the sign, and then I flipped the equation to make it easy to graph
3 > -0.4x
-7.5 < x
x > -7.5
[5] Divide both sides by -2.2, flip the sign
-2.2x ≤ -6.6
x ≥ 3
[6] Multiply both sides by -8, flip the sign
> 2
x < -16

probability : 1/3
Explanation:
- weightlifting benches : 4
probability = selected/total
Here,
- probability = 4/12 = 1/3 = 0.33
