The equation y=2(x-1)^2-5y=2(x−1)

marin [14]

Answer:

(b) It is symmetrical about $x = 1$

Step-by-step explanation:

Given

$y = 2(x - 1)^2 - 5$

See attachment for options

Required

True statement about the graph

First, we check the line of symmetric

$y = 2(x - 1)^2 - 5$

Expand

$y = 2(x^2 - 2x + 1) - 5$

Open bracket

$y = 2x^2 - 4x + 2 - 5$

$y = 2x^2 - 4x -3$

A quadratic equation $y = ax^2 + bx + c$ has the following line of symmetry

$x = -\frac{b}{2a}$

By comparison, the equation becomes:

$x = -\frac{-4}{2*2}$

$x = \frac{4}{4}$

$x = 1$

Hence, the line of symmetry is at: $x = 1$

(b) is true.

7th grade math pls help

cestrela7 [59]

Answer:

Step-by-step explanation:

The volume of rectangular prism is l x w x h

So, 12 x 6 x 8 =576

Volume of triangular prism is l x w /2 x h

So, 6x8=48/2= 24

24x12=288

576/288=2

This shows that the rectangular prism is 2 times larger than the triangular prism.

Therefore, the answer is A.

1) In Math class Mike and Karen are looking at two numbers: 152 and 33 +. 53.

vladimir2022 [97]

Answer:

Mike is right. 152 is larger than 33 + 53/

Step-by-step explanation:

First we need to add 53 + 33 to see if it will equal up ro 152. So 53 + 33 = 86.

86 is less than 152, so Mike is correct and Karen is wrong, as usual.

sineoko [7]

Answer:

The simplified expression for f(g(x)) is x.
The simplified expression for g(f(x)) is x.
The functions are inverses of each other.

Step-by-step explanation:

<u>Given</u>:

$f(x)=\dfrac{1}{8}x^3\\\\g(x)=2x^{\frac{1}{3}}$

We find that ...

$f(g(x))=\dfrac{1}{8}(2x^{\frac{1}{3}})^3=\dfrac{1}{8}(2^3)(x^{\frac{3}{3}})=\dfrac{8}{8}x\\\\\boxed{f(g(x))=x}\\\\g(f(x))=2\left(\dfrac{1}{8}x^3\right)^{\frac{1}{3}}=2\left(\dfrac{1}{8^{\frac{1}{3}}}\right)(x^{\frac{3}{3}})=\dfrac{2}{2}x\\\\\boxed{g(f(x))=x}$

So, the statements that apply are ...

The simplified expression for f(g(x)) is x.
The simplified expression for g(f(x)) is x.
The functions are inverses of each other.
