You have the following function:
g(x) = 3x - 7
In order to determine th value of x when g(x) = -4, you equal the previous expression to -4 and solve for x, just as follow:
g(x) = 3x - 7 replace g(x) = -4
-4 = 3x - 7 add 7 both sides
-4 + 7 = 3x simplify
3 = 3x divide by 3 both sides
3/3 = x
x = 1
Hence, the anser is x = 1
X=-12 because you subtract the 9 since it is positive and bring it to the -3 and that gets you -12 and subtract the x from 2x because it is positive and you get x=-12
Answer:
(x-2)^2+y^2=16
Step-by-step explanation:
If the center of the circle is (h,k) and the radius is r, then the equation of a circle is (x-h)^2+(y-k)^2=r^2 (with the Pythagorean theorem)
So, the center of this circle 0 is (2,0) and the radius is 4. Thus, the equation is (x-2)^2+y^2=16
Answer:
5 is less than or equal to 5/2x+5
Step-by-step explanation:
It is less than or equal to because the shaded part is below the line and the line is solid.
