They added it wrong. They added it like this:

$100 + 700 + 800 + 560$
When it shouldve been this:

$100 + 70 + 80 + 56$
They just added a place marker in all numbers below 100.

For a given input value x, the function g outputs a value y to satisfy the following equation.

ipn [44]

Answer:

Step-by-step explanation:

we have

Solve for y

That means-----> isolate the variable y

Subtract both sides -2

Divide by -5 both sides

Rewrite

Convert to function notation

Let

g(x)=y

Can someone help and explain ? thank you !

$\sf Hello!$

$\sf y = 2x^{2} + 4x - 3$

$\sf Discriminant$ :

= $\sf b^{2} - 4ac$

= $\sf (4)^{2} - 4.(2).(-3)$

= $\sf 16 - (-24)$

= $\sf 16 + 24$ = $\sf 40$

$\sf Since,$
$\sf D \:is\:Greater\: than\: 0.$

$\sf Roots\: are\: Real\: and\: Distinct$

$\sf Hence,$

$\sf y = 2x^{2} + 4x - 3\: have\: A.\: Two\: real\: roots$

Which transformations could have taken place? select two options. r0, 90° r0, 180° r0, 270° r0, –90° r0, –270°

Lelechka [254]

The complete question is

"One vertex of a polygon is located at (3, –2). After a rotation, the vertex is located at (2, 3). Which transformations could have taken place? Select two options. R0, 90° R0, 180° R0, 270° R0, –90° R0, –270°"

The transformations that could have taken place are R0, 270°or R0, -90°

Let the vertex be V.

So, we have:

V = (3, –2) before rotation

V' = (2, 3) after rotation

The possible transformations from V to V' are;

A 90 degrees counterclockwise rotation (r0, -90) is given :

(x, y) --(-y , x)

So,

(3, –2) --- (2, 3)

A 270 degrees clockwise rotation (r0, 270) is given :

(x, y) --(-y, x)

So,

(3, –2) --- (2, 3)

By comparing the endpoints of the rotations to V' = (2, 3), we can conclude that the transformations that could have taken place are: r0, 270°or r0, -90°.
