Which equation shows y=−12x+4 is in standard form? 2x + y = 8 2x−y=8 x + 2y = 8 x+2y=−8

drek231 [11]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have:

$y=-\dfrac{1}{2}x+4$

Convert:

$y=-\dfrac{1}{2}x+4$ multiply both sides by 2

$2y=-x+8$ add x to both sides

$x+2y=8$

Y= - x^2 + 4x + 6 in vertex form

serg [7]

<h3>HI THERE!</h3>

$\rm \color{lime}(2,10)$

step-by-step explanation:

$\rm \color{lime}y = - {x}^{2} + 4x + 6$

identify the coefficients

<h2 /><h2> $\rm \color{lime}a = - 1,b = 4$ </h2>

substitute the coefficient into the expression
find the x-coordinate of the vertex by substituting a = - 1 and b=4 
 $\tt \tiny \: x = - \frac{b}{29}$

 $\rm \color{lime}x = - \frac{4}{2x( - 1)}$ 

solve the equation for X
find the y-coordinate of the vertex by evaluating the function for x = 2

 $\rm \color{lime}y = - {x}^{2} + 4x + 6,x = 2$ 

calculate the function value for x = 2

$\rm \color{lime}y = 10$

since the value of the function is 10 for x = 2 the vertex of the graph of the quadratic function is a (2,10)

 $= \rm \color{hotpink} (2,10)$ 

hope it helps

If y varies inversely as x, and y = 4 as x = 8, find y for the x-value of 2.

anyanavicka [17]

Because y varies inversely as x, instead of directly, you will need to multiply x by a fractional number (or divide x) in order to find y.
When x=8, y=4. Therefore, to find y, you need the "equation" y=(1/2)(x) or y=x/2.
So, when x=2, y=(1/2)(2) or y=2/2.
And so, y=1
Hope this helps!
