Step-by-step explanation:
3x - x = 2x
2(x + 2) = 2x + 2
for every number of x, 2x + 2 would always be larger than 2x.
so there is no solution, since the given equation is 2x is greater than 2x + 2.
The equation of a circle with the center (4,-3) and a radius of 3 is:
(x-4)^2+(y+3)^2=9
Step-by-step explanation:
Given
Radius = r = 3
Centre = (h,k) = (4,-3)
The general form of equation of circle is:
Putting the values of center and radius
Hence,
The equation of a circle with the center (4,-3) and a radius of 3 is:
(x-4)^2+(y+3)^2=9

Answer:
the slope is -3 and the y intercept is -7
Quadratic
y = ax^2 + bx + d
c (x) = ax^2 + bx + d
c (3) = a (3^2) + b (3) + d
c (3) = 9a + 3b + d = 15.50
c (7) = a (7^2 + b (7) + d
c (7) = 49a + 7b + d = 23.50
c (12) = a (12^2) + b (12) + d
c (12) = 144a + 12b + d = 56
solve using simultaneous equations... to get a b and d
use that to solve for x = 5
hope this helps?
