Equality Properties

Step-by-step explanation:

Step 1: Define

20 - 2x > -2(x + 2) + 4x

Step 2: Solve for x

Distribute -2: 20 - 2x > -2x - 4 + 4x
Combine like terms: 20 - 2x > 2x - 4
Add 2x on both sides: 20 > 4x - 4
Isolate x term: 24 > 4x
Isolate x: 6 > x
Rewrite: x < 6

Here we see that any value x less than 6 would work as a solution to the inequality.

Answer:

x<6

Step-by-step explanation:

expand

subtract 20 from both sides

simplify

subtract 2x from both sides

simplify

multiply both sides by -1(reverse the inequality)

simplify

divide both sides by 4

The graph of F(x) can be stretched vertically and flipped over the x axis to produce the graph of G(x) if F(x)=x^2 which of the

ladessa [460]

Answer:

g(x) = -5x²

(option B)

Step-by-step explanation:

we know that our original graph, f(x) = x² is a parabola.

So, we can consider what happens when we adjust the function/equation of a parabola.

when we "vertically stretch" a parabola, we are increasing the value of x.

think of it this way: the steepness of a slope is rise over run. If we rise ten, and run one, that's going be a lot more steep than if we rise 1, run 1.

Let's say our x = 5

if f(x)=x²

f(5) = 25

> y value / steepness is 25

f(x) = 3x²

f(5) = 75

> y value / steepness is 75

So, we are looking for an equation with an increase in x present.

When a parabola has been flipped over the x-axis, we know that the original equation now includes a negative

suppose that x = 1

if y = x² ; y = 1² = 1

if y = -(x²) ; y = -(1²) ; y = -1

So, when we set x to be negative, we make our y-values end up as negative also (which makes the graph look as if it has been flipped upside-down)

This means that we are looking for a function with a negative x value.

So, we are looking for a negative x-value that is multiplied by a number >1

The graph that fits our requirements is g(x) = -5x²

hope this helps!!

Tony rounded each of the numbers 1, 143 and 1, 149 to the nearest hundred which word correctly compares the rounding numbers

Montano1993 [528]

Full Question:

Tony rounded each of the numbers 1,143 and 1,149 to the nearest hundred. Which choice correctly compares the rounded numbers?

$1,000 = 1,000$

$1,140< 1,150$

$1,100 = 1.100$

$1,140>1,150$

Answer:

$1,100 = 1,100$

Step-by-step explanation:

Given

1,143 and 1,149

Required

Which of the option is correct

We start by approximating both numbers to nearest digit

1,143; when approximated to nearest hundred is 1,100

1,149; when approximated to nearest hundred is also 1,100

Hence;

1,143 ≅ 1,100

1,149 ≅ 1,100

Comparing both results, we have that

$1,100 = 1,100$

From the list of given options, option C is correct;
