Answer:
18, 19(which has two) 20(has two)
Step-by-step explanation:
Just find the ones that appear more than one time.
Answer: No solution
<u>Step-by-step explanation:</u>
x - 3y = 2 → x = 3y + 2
2x - 6y = 6
2(3y + 2) - 6y = 6 <em>substituted x with 3y+2</em>
6y + 4 - 6y = 6 <em>distributed 2 into 3y+2</em>
4 = 6 <em>simplified (6y - 6y = 0)</em>
4 = 6 is a FALSE statement so there is NO SOLUTION

If you think about what times what equals 93.
Type in the calculator square root of 93, and you get 9.643650761... but you want to round this decimal to the nearest tenth or hundredth... so 9.64
Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.
squared distance from P(x,y) to focus F(2,2)
(x - 2)² + (y - 2)²
squared distance from P(x,y) to the directrix x=8.
(x-8)²
Those are equal in a parabola,
(x - 2)² + (y - 2)² = (x-8)²
x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64
y² - 4y - 46 = -12x
That's a sideways parabola,
x = -(y² - 4y - 46)/12
