Which of these systems of linear equations has an infinite number of solutions? A. 5x - 2y = 10
12x - 4y = 20

B. 5x - 2y = 10
10x - 4y = 12

C. 5x - 2y = 10
10x - 4y = 20

D. 5x - 2y = 10
12x - 4y = 10

the axial of symmetry

step-by-step explanation:

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

plz mark brainliest i took the test
