Solve the inequality

const2013 [10]

$\huge\text{Hey there!}$

$\mathsf{\dfrac{x}{4}\geq-6}$

$\large\text{SUBSITUTE 1 where x is at temporarily, so we can simplify both}\\\large\text{sides of your inequality}$

$\large\text{NEW EQUATION: }\mathsf{\dfrac{1}{4}x \geq-6}$

$\large\text{MULTIPLY by 6 to BOTH SIDES}$

$\mathsf{4\times\dfrac{}{}x \geq 4\times-6}$

$\large\text{CANCEL out: }\mathsf{4\times\dfrac{1}{4}}\large\text{ because that gives you the value of 1}$

$\large\text{KEEP: }\mathsf{4\times-6}\large\text{ because it helps you find out the number or value}\\\large\text{that is being compared to your x-value}$

$\mathsf{4\times-6=\boxed{\bf -24}}$

$\large\text{So, the number \underline{-24} is being compared to your x-value}$

$\bullet\large\text{ Your circle is CLOSED and it is shaded to the right side of the}\\\large\text{number}\huge\checkmark\\\\\\\large\textsf{Random fact about the inequality}\uparrow$

$\boxed{\boxed{\large\text{Answer: \bf x}\bf \geq\large\textsf{\bf -24 \huge\text{Option D.}}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

Malik has 3 boxes of baseball cards. Each box has 2 containers with 8 cards in each container.

horrorfan [7]

Answer:

Step-by-step explanation:

I think he did the first step correct, 8×2=16.

He did that because in each box there are 2 containers with 8 cards. so all together there are 16 cards in each box.

But then he should've multiplied 16×3=48 because there are three containers with the 16 cards.

Answer this question plz thanks

Marina86 [1]

Answer:

Option A

Step-by-step explanation:

The area outside of the semicircle is the difference of the areas of the rectangle and the semicircle.

<u>Area of rectangle:</u>

A₁ = w(w + 5) = w² + 5w

<u>Area of the semicircle:</u>

A₂ = 1/2*πd²/4 = 1/8*πw²

<u>The area we are looking for is:</u>

A = A₁ - A₂
A = w² + 5w - 1/8πw²

Correct choice is A

Evaluate The quantity of x cubed plus 3x squared minus 2x plus 7 divided by the quantity of x minus 2 end quantity period.

Minchanka [31]

The value of x^3 + 3x^2 - 2x + 7 divided by x- 2 is (x^2 + 5x + 8) + 23/(x - 2)

<h3>What is a quotient?</h3>

Quotients involve the result of dividing a dividend by a divisor.

In other words, quotient means division or the result of a division operation

<h3>How to solve the quotient?</h3>

The quotient expression is given as:

(x^3 + 3x^2 - 2x + 7)/x- 2

Expand the numerator in the above expression

(x^3 + 5x^2 - 2x^2 + 8x - 10x - 16 + 23)/(x - 2)

Rearrange the terms of the numerator in the above expression

(x^3 + 5x^2 + 8x - 2x^2 - 10x - 16 + 23)/(x- 2)

Factorize the numerator in the above expression

[x(x^2 + 5x + 8) - 2(x^2 + 5x + 8) + 23]/(x - 2)

Factor out x^2 + 5x + 8

[(x -2)(x^2 + 5x + 8) + 23]/(x - 2)

Split the fractions

(x -2)(x^2 + 5x + 8)/(x - 2) + 23/(x - 2)

Divide the common factors

(x^2 + 5x + 8) + 23/(x - 2)

Hence, the value of x^3 + 3x^2 - 2x + 7 divided by x- 2 is (x^2 + 5x + 8) + 23/(x - 2)
