Can someone help me solve the inequality-2x+4>8 with the steps? Thanks

$\huge\text{Hey there!}$

$\rm{-2x + 4 > 8}$

$\large\textsf{SUBTRACT 4 to BOTH SIDES}$

$\rm{-2x + 4 - 4 > 8 - 4}$

$\large\textsf{CANCEL puts 4 - 4 because that gives you 0}$

$\large\textsf{KEEP: 8 - 4 because that helps solve for the x-value}$

$\rm{8 - 4 = \boxed{\bf 4}}$

$\rm{NEW\ EQUATION: -2x > 4}$

$\large\textsf{DIVIDE -2 to BOTH SIDES}$

$\mathsf{\dfrac{-2}{-2}>\dfrac{4}{-2}}$

$\mathsf{CANCEL\ out: \dfrac{-2}{-2}\ because\ that\ gives\ you\ 1}$

$\mathsf{KEEP: \dfrac{4}{-2} \ because \ it \ helps \you \ compare\ to \ the \ x-value }$

$\mathsf{\dfrac{4}{-2} = \boxed{\bf -2}}$

$\rm{\bold{x < -2 }}$

$\rm{It\ is \ an\ O PENED \ circle \ shaded \ to \ the \ left \ side \ of \ the \ number \ line}$

$\boxed{\boxed{\large\textsf{Answer: } \mathsf{\bf x < -2}}}\huge\checkmark$

suppose that f(x)=x^2 and g(x) = -2/3x^2 which statement best compares that graph of g(x) with the graph of f(x)?

vodka [1.7K]

Answer:

$f(x) = x^2 , g(x)= -\frac{2}{3}x^2$

And we want to compare the two functions.

The minus signs is a reflection around the x axis and the value of 2/3 is a compression of the original function so then the best answer would be:

The graph of g(x) is the graph of f(x) compressed vertically and reflected over the x axis

Step-by-step explanation:

We have the following two function given:

$f(x) = x^2 , g(x)= -\frac{2}{3}x^2$

And we want to compare the two functions.

The minus signs is a reflection around the x axis and the value of 2/3 is a compression of the original function so then the best answer would be:

d) The graph of g(x) is the graph of f(x) compressed vertically and reflected over the x axis
