Add 21 to both sides, then that means you get
K>22
there is no need to change the signs, as you are not multiplying by a negative or anything
Answer:
no solution
Step-by-step explanation:
solve the equation
3x - 8 = 3(x-4) + 1
3x - 8 = 3x - 11
3x + 3 = 3x
x + 3 = x
A number x plus 3 cannot equal a number x.
Answer:
See diagram
Step-by-step explanation:
The line with the slope of
has the equation

This line passes through the point (-1,2), so

The line has the equation

This line intersects the y-axis at point (0,0.5) and the y-axis at point (1/3, 0). Plot these points and connect them with the straight line (see attached diagram)
Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
