Answer:
x = 5, Y = 4
Step-by-step explanation:
3x -2y = 7
-3x +9y = 21. (multiple the whole thing by 3 to get the xs to cancel)
7y = 28
y = 4
substitute y to find x
3x - 2(4) = 7
3x -8 = 7
3x = 15
x = 5
Answer:
x = 0
Step-by-step explanation:simplified is 8x-5y=0
The equation of parabola is

.
The canonical equation of parabola is

and this parabola has branches that go in positive direction of x-axis.
Since in your equation x is changed to y and y to x, then the <span>branches of the parabola go in positive y-axis direction, the vertex is placed at the origin.

Perimeter of the photo frame is 64 cm.
According to the question
Area of a square photo frame is 256 cm2.
The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side.
Area of the square = side × side = a × a

Side(a) =
= 16
Side(a) = 16
Perimeter of the photo frame:
Formula for perimeter of a square:
Perimeter p = 4a
p = 4 × 16
p = 64
Perimeter of the photo frame is 64 cm.
