Answer:
All real numbers
Step-by-step explanation:
Solve a system of equations by elimination
With the equation given, you can solve for y to get: y = x -
Then, substitute this value in on the equation.
x - 5(x -
) = 6
x - x + 6 = 6
6 = 6
The solution is all real numbers
Answer:
Option A -
Step-by-step explanation:
We have given the expression
We have to find the value of the expression ?
Solution :
Step 1 - Write the expression
Step 2 - Applying symbol rule i.e. multiplication of positive into negative is always negative,
Step 3 - Solve
Therefore, The value of the expression is
So, Option A is correct.
Answer:
y = - (x - 1)² + 2
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and the directrix.
Using the distance formula
= | y - 6 |
Square both sides
(x - 1)² + (y + 2)² = (y - 6)² ( expand the factors in y )
(x - 1)² + y² + 4y + 4 = y² - 12y + 36 ( subtract y² - 12y from both sides )
(x - 1)² + 16y + 4 = 36 ( subtract 4 from both sides )
(x - 1)² + 16y = 32 ← subtract (x - 1)² from both sides )
16y = - (x - 1)² + 32 ( divide all terms by 16 )
y = - (x - 1)² + 2
