What is y=3x^2-2 in vertex form

Nata [24]

$\bf \qquad \qquad \textit{parabola vertex form}
\\\\\\
y=a(x-{{ h}})^2+{{ k}}\\
x=a(y-{{ k}})^2+{{ h}}\qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-----------------------------\\\\
y=3x^2-2\iff y = 3(x-0)^2-2$

Enter the correct answer in the box. Write your answer in the form y = mx + b, using the appropriate inequality symbol in place

Darya [45]

Answer:

$y\geq -1x-4$

Step-by-step explanation:

A: (-4,0)

B:(0,-4)

$m=\frac{y2-y1}{x2-x1} \\m=\frac{-4-0}{0--4} =\frac{-4}{4}=-1$

y=mx+b

to find b , we replace the Point B in x and y.

$y=mx+b\\-4=-1(0)+b\\-4=b$

So the equation of the line is:

$y\geq -1x-4$

A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centim

dusya [7]

Answer:

Step-by-step explanation:

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

length + width = 27

So, x + (1/2)x = 27

(3/2)x = 27

x = 27(2/3) = 18 (1/2)x = 9

Answer: length = 18 cm and width = 9 cm

liraira [26]

Answer:

(-6,8)

Step-by-step explanation:

2x + 9y = 60

-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->

2x+ 81x + 558 = 60 -->

83x + 558 = 60 -->

83x = -498 -->

x = -6 -->

y = 9(-6) + 62 -->

y = 8
