Solve the system of equations by the substitution method. (3x + y=-5
12x + 3y=13
O no solution
0 (-3.6)
O (7,-4)
0 (-4.7)

Step-by-step explanation:

Are you certain you wrote the question accurately?—because none of the choices is correct.

rearrange 3x+y =-5 to solve for y:

y = -3x-5

substitute -3x-5 for y into the second equation:

12x + 3y = 13

12x + 3(-3x-5) = 13

12x - 9x - 15 = 13

3x = 28

x = 28/3

y = -3x-5 = -33

solution: (28/3, -33)

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
