Solve the equation. <br><br><br> 12=2+z/-6

Bogdan [553]

Answer:

$\boxed{\bold{z=-60}}$

Step-by-step explanation:

Switch Sides

$\bold{2+\frac{z}{-6}=12}$

Subtract 2 From Both Sides

$\bold{2+\frac{z}{-6}-2=12-2}$

Simplify

$\bold{\frac{z}{-6}=10}$

Multiply Both Sides By -6

$\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}$

Simplify

$\bold{z=-60}$

What is the axis of symmetry of the function f(x)=−(x+9)(x−21)?

Elena L [17]

Answer:

Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.

Step-by-step explanation:

i) f(x) = -(x+9)(x-21)

ii) therefore y = f(x) = - $x^{2}$ + 12x + 189 = - ( $x^{2}$ - 12x +36) + 36 + 189

iii) therefore y = f(x) = - $(x-6)^{2}$ + 225

iv) when x = 6 then y = 255

Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
