Solve the inequality <br><br><br> what is the solution?

bija089 [108]

Answer:

The solution to the inequality is:

$2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}$

Please also check the graph of the solution to the inequality.

Step-by-step explanation:

Given the inequality

$2\ge \frac{g}{-4}$

switch sides

$\frac{g}{-4}\le \:2$

Multiply both sides by -1 (reverse the inequality)

$\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)$

Simplify

$\frac{g}{4}\ge \:-2$

Multiply both sides by 4

$\frac{4g}{4}\ge \:4\left(-2\right)$

Simplify

$g\ge \:-8$

Therefore, the solution to the inequality is:

$2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}$

Please also check the graph of the solution to the inequality.

F(t) = 3t^3 - 4t + 6t^2 and g(n) = 5t^3 + 2t^2 - 3t. What is f(t) - g(t)

nikdorinn [45]

Answer:

- 2t³ + 4t² - t

Step-by-step explanation:

f(t) - g(t)

= 3t³ - 4t + 6t² - (5t³ + 2t² - 3t) ← distribute parenthesis by - 1

= 3t³ - 4t + 6t² - 5t³ - 2t² + 3t ← collect like terms

= - 2t³ + 4t² - t

A rectangle has an area of 25 square feet. A similar rectangle has an area of 240 square feet. What is the ratio of the areas of

Lady_Fox [76]

Answer:

The ratio of the areas of these similar rectangles is 5:48.

Step-by-step explanation:

Let us convert area into fraction.

Ratio of the area of first rectangle to the area of second rectangle = $\frac{Area of first rectangle}{Area of second rectangle}$

= $\frac{25}{240}$

$= \frac{5}{48}$

Hence, the ratio of the areas of these similar rectangles is 5:48.
