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.

Step-by-step explanation:

60% of 220 is 132. So thats the sale. The tax is 7% of that. So 7% of 132 is 9.24 So 132+9.24=141.24

Given: f(x) = x - 7 and h(x) = 2x +3

forsale [732]

Answer:

h(f(x)) = 2x - 11

Step-by-step explanation:

substitute for x in h (x), the values of f(x)

h(f(x))= 2(x-7)+3

=2x-14+3

=2x-11

Solve:<br> 3x - 4+2(x-5)= 9x + 8- 2x

Zepler [3.9K]

Answer:

x = -11

Step-by-step explanation:

3x - 4 + 2(x - 5) = 9x + 8 - 2x

3x - 4 + 2x - 10 = 9x + 8 - 2x

3x + 2x - 9x + 2x = 8 + 10 + 4

- 2x = 22

- x = 22/2

- x = 11

x = - 11
