An item costs x dollars and then a 20% discount is applied

Marat540 [252]

Answer:

If an item is x dollars and 20% discount is applied, the new price will be: 0.8x

Step-by-step explanation:

100 - 20%(20) = 80

80 = 80% or 0.8

So, the remaining of the price of x will be 0.8x.

Given that ABCD is a rhombus, what is the value of x?<br>(3x - 26)

ExtremeBDS [4]

<h2>The required "option B) $20.75\°$ " is correct.</h2>

Step-by-step explanation:

You can refer figure:

To find, the value of x = ?

We know that,

Consecutive angles are supplementary

The diagonals bisect the angles.

$2x\°+2(3x+7)\°=180\°$

Divided by 2 both sides, we get

⇒ $x\°+(3x+7)\°=90\°$

⇒ $x\°+3x+7\°=90\°$

⇒ $4x=90\°-7\°$

⇒ 4x = $83\°$

⇒ $x=\dfrac{83\°}{4}$

⇒ $x=20.75\°$

∴ The value of x = $20.75\°$

Thus, the required "option B) $20.75\°$ " is correct.

1.Solve the inequality (x-2)(x+1) ≥ 0 .

scoray [572]

Answer:

#1: inequality form: x ≤ –1 or x ≥ 2

interval notion: ( -∞,-1] U [2,∞)

#2: false/no solution

#3: A) point form: (3,9)(-1,1)

equation form: x= 3,y=9 and x= -1,y=1

B)point form: (1,7)(7,1)

equation form: x=1,y=7 and x=7,y=1

Step-by-step explanation:

#1: solve for x by simplifying both sides of the inequality, then isolating the variable.

#2: N/A

#3: solve for the first variable in one of the equations, then substitute the results into the other question.

Given the function defined in the table below, find the average rate of change, insimplest form, of the function over the interv

Reil [10]

To find the average rate of change in a interval

$a\leq x\leq b$

We use the following formula:

$\frac{f(b)-f(a)}{b-a}$

Applying this to our interval

$6\leq x\leq15$

We have the following rate of change:

$\frac{f(15)-f(6)}{15-6}=\frac{107-53}{9}=\frac{54}{9}=6$

We have an average rate of change equals to 6.
