Step-by-step explanation:

To find x, substitute the values and solve.

R = 2x + 9y

It becomes:

2x + 27 = 13

Rearrange and solve

2x = -14

x = -7

Graph the equations below using slope-intercept form

MA_775_DIABLO [31]

Look at the picture.

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

$m=\dfrac{\Delta y}{\Delta x}$

We have $y=\dfrac{4}{5}x-1$

$b=-1\to(0,\ -1)$

$m=\dfrac{4}{5}\to\dfrac{\Delta y}{\Delta x}=\dfrac{4}{5}$

The graph shown is a translation of the graph of f(x)=x^2. Write the function in vertex form.

Gnesinka [82]

$\sf \longrightarrow \: f(x) = {x}^{2}$

Write the parent function in the standard form I.e.

$\boxed{ \tt \:y =a(x - h) \times 2 + k }$

Where,

a = 1
h = 0
k = 0

$\sf \longrightarrow \:y= 1(x - 0)^{2} \times 2 + 0$

$\sf \longrightarrow \: y = (x - 0) ^{2} \times 2 + 0$

$\sf \longrightarrow \: y = {x}^{2} \times 2$

$\sf \longrightarrow \: y = 2{x}^{2}$
