Three multiplied by the sum of 4 and a number is the same as 12 more than the number. Find the number. If nis "the number," which equation could be used to solve for the number?
413+51)= 0+12
314 4 7 = 0+12
1030+4=0412

3(4+n) = 12+n is an equation that could be used.

12n = 12+n

11n = 12

n= 1+1/11

Step-by-step explanation:

the radius is 2 times the diameter.

step-by-step explanation:

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)
