Given the equation y − 3 = one half(x + 6) in point-slope form, identify the equation of the same line in standard form.

Schach [20]

Answer:

A. $x-2y=-12$

Step-by-step explanation:

We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.

$y-3=\frac{1}{2}(x+6)$

Since we know that standard form of equation is: $ax+by=c$ , where, a, b and c are constants.

Let us multiply both sides of our given equation by 2.

$(y-3)*2=2*\frac{1}{2}(x+6)$

$2y-6=x+6$

Let us add 6 to both sides of our equation.

$2y-6+6=x+6+6$

$2y=x+12$

Let us subtract x from both sides of our equation.

$2y-x=x-x+12$

$2y-x=12$

Multiply both sides of our equation by -1.

$-2y+x=-12$

Rearranging our equation we will get,

$x-2y=-12$

Therefore, the standard form of our given equation is $x-2y=-12$ and option A is the correct choice.

The expression LaTeX: -5t^2+40t

dlinn [17]

Answer:

8 seconds

Step-by-step explanation:

Given

h = - 5t² + 40t

When the object hits the ground then h = 0

Substitute h = 0 into the function and solve for t

- 5t² + 40t = 0 ← factor out - 5t from each term

- 5t(t - 8) = 0

Equate each factor to zero and solve for t

- 5t = 0 ⇒ t = 0

t - 8 = 0 ⇒ t = 8

t= 0 denotes the time of launch

t = 8 denotes the time it hits the ground
