What is y=1/2(x+3)^2+10 in standard form

anyanavicka [17]

Answer:

Simplified equation in standard form: $y=\frac{1}{4}x^{2}+12\frac{1}{4}$

Original equation in standard form: $y=1/2(x+3)^2+10$

Step-by-step explanation:

$y=\frac{1}{2}(x+3)^2+10$

Step 1: Distribute the $\frac{1}{2}$ :

$y=(\frac{1}{2}*x+\frac{1}{2}*3)^2+10$

$y=(\frac{1}{2}x+1\frac{1}{2})^2+10$

Step 2: Take $(\frac{1}{2}x+1\frac{1}{2})$ and square it :

$y=(\frac{1}{2}x+1\frac{1}{2})^2+10$

$y=(\frac{1}{2}x)^{2} +(1\frac{1}{2})^2+10$

$y=(\frac{1}{2}x*\frac{1}{2}x)+(1\frac{1}{2}*1\frac{1}{2})+10$

$y=\frac{1}{4}x^{2}+2\frac{1}{4}+10$

Step 3: Add the constants:

$y=\frac{1}{4}x^{2}+(2\frac{1}{4}+10)$

$y=\frac{1}{4}x^{2}+(12\frac{1}{4})$

Step 4: Get rid of the parenthesis:

$y=\frac{1}{4}x^{2}+12\frac{1}{4}$

Can somebody help me with this and show work ?? :)

kobusy [5.1K]

Answer: C.

Step-by-step explanation:

If the figure gets rotated 270ᴼ, then all of the transformed sides are perpendicular to the sides of the original figure.

The slope of DE is 2/4 (2 units up, 4 units over) or 1/2. If D’E’ is perpendicular to DE, then the slopes have negative reciprocals.

DE’s slope: 1/2

D’E’ slope: -2/1 or -2 (down 2, over 1)
