X is 18
You need to algebraically move things around by adding/dividing on both sides (work shown in the picture).
Answer:
x= -1/2 and -32
y = -10
Step-by-step explanation:
1) 2(-4x-8y)= (-48)2
8x+3y =-34
*to create a way to cancel out the x*
2) -8x-16y= -96
8x+3y= -34
*add them
-8x +8x =0
-16y + 3y = -13y
-96+ -34= -130
3) -13y =-130
isolate y
4) y = -10
*plug in* to find x into both original equations*
5) 8x + 3(-10) = -34. -4x-8(-10)= -48
*follow order of operations to solve for x
6) 8x -30 =-34. -4x +80 = -48
7) 8x =-4. -4x =128
8) x= -1/2. x = -32
A circle is evenly divided into six equal triangles.
Answer:
The equation of the axis of symmetry for this parabola is x = 0.
Step-by-step explanation:
For parabola's, it's axis of symmetry always goes through the vertex of the parabola. In other words, the axis of symmetry is vertical line that goes through the x-coordinate of the vertex.
Now, the vertex is given as (0,3) which is at x = 0, y = 3.
Thus, the vertical line that goes through the x-coordinate of the vertex will be x = 0
Thus, the equation of the axis of symmetry for this parabola is x = 0.
