3x^2 +6y^2 = 18
Divide each term by 18 to make the right side equal 1:
3x^2/18 + 6y^2/18 = 1
Simplify each term:
x^2/6 + y^2/3 = 1
The form of an eclipse is written as (x-h)^2/a^2 + (y-k)^2/b^2 =1
Match the values in the ellipse to the standard form:
a = √6
b=√3
k = 0
h = 0
The center = (h,k) = (0,0)
Vertex is h +a, k = (√6,0) and (-√6,0)
Focus is h+c,k = (√3,0) and (-√3,0)
Answer:
A. x=10
B. x=-19
C. x=53
D. x=-1/28
Step-by-step explanation:
A.
2x+3=23
2x=20
x=10
B.
-3(x+9)=30
x+9=-10
x=-19
C.
0.75x-12.75=27
0.75x=39.75
x=53
D.
1/2x+6=-8
1/2x= -14
1=-28x
x=-1/28

The angle of 80 degrees is the same angle as the one with the equation. That equation has to equal 80 somehow.
------------------------------------------
80 - 20 (from equation) = 60
60 ÷ 2 (also from equation) = 30
--------------------------------------------
x = 30 To make sure plug it in
(2 x 30)+ 20
60 + 20 = 80
---------------
x should equal 30
