What is the x-intercept
1/2x - 3y = 8

Answers

Answer 1
Answer: so first make it into slope intercept form y=mx+b

1/2x-3y=8
subtract 1/2x from both sides
-3y=8-1/2x
multiply both sides by -1
3y=1/2x-8
divide both sides by 3
y=1/6x-8/3

the x intercept is when y=0
so set y to zero
0=1/6x-8/3
add 8/3 to both sides
8/3=1/6x
multiply both sides by 6
16=x

the x intercept is 16
Answer 2
Answer: x intercept is when y = 0
so 1/2 x - 0 = 8
solving for x
1/2 x = 8
multiply both sides by 2
x = 16 is the y intercept

Select the symbol = (equal to) or ≠ (not equal to) to make the expression true.{2, 4, 6} ? {6, 4, 2}

Answers

Answer:

The symbol would be '='

Step-by-step explanation:

Two sets are called equal if they contains same elements in them ( however in any order ),

Here, the given sets,

{2, 4, 6}

{6, 4, 2}

Since, both sets having the elements 2, 4 and 6,

Hence, we can say that,

Sets {2, 4, 6} and {6, 4, 2} are equal sets,

Or {2, 4, 6} = {6, 4, 2}
It is equal to 2+6=8 4+4=8
