What solutions do these equations have?
one solution, no solution, infinite solution.

a. 7(y+3)=5y+8.
b. 10+6x=2(5+3x)
c. 3x+5-x=2x+7
d. 4x-4=2x+8

A.One solution

B.infinite solution

C.No solution

D.One solution

Step-by-step explanation:

A.7y+21=5y+8  so y=-13/2

B.10+6x=10+6x  x belongs to all real numbers

C.2x+5 and 2x+7 The leftside doesn't equal to the rightside

D.2x=12 x=6 One solution

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

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)
