6.4/8 = y/6 = x/7

0.8/1 = 4.8/6 = 5.6/7

6.4/8 = 4.8/6 = 5.6/7

x = 5.6 ; y = 4.8

I think that’s how you do it but not 100% sure

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.

Solve for x<br><br> 33=x/2+15

rewona [7]

Answer:

$x=36$

Step-by-step explanation:

Solve for $x$ by simplifying both sides of the equation, then isolating the variable.

Therefore, $x = 36$ .

To check your answer, apply 36 to where $x$ is.

$33=\frac{36}{2} +15$

⇒ $33=18+15$

$18+15=33$ ☑
