Plz help asap... Explain as much as possible to me plz

Solnce55 [7]

Answer:

see explanation

Step-by-step explanation:

Since the 2 figures are similar then the ratios of corresponding sides are equal, that is

$\frac{8}{x}$ = $\frac{18}{6}$ ( cross- multiply )

18x = 48 ( divide both sides by 18 )

x = $\frac{48}{18}$ = $\frac{8}{3}$ = 2 $\frac{2}{3}$

Similarly

$\frac{5}{y}$ = $\frac{18}{6}$ ( cross- multiply )

18y = 30 ( divide both sides by 18 )

y = $\frac{30}{18}$ = $\frac{5}{3}$ = 1 $\frac{2}{3}$

State the vertex and axis of symmetry of the graph of y=ax2+c.

Neporo4naja [7]

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is $y=ax^2 + bx +c$

There is no bx in our given equation, so we put 0x

Given equation can be written as $y=ax^2 + 0x +c$

a=a , b=0

Now we use formula to find vertex

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

$x=\frac{-0}{2a}=0$

Now we plug in 0 for 'a' and find out y

$y=a(0)^2 + 0x +c= c$

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry
