if a watch cost $40 and you pay 6.5% sales tax, how much will the tax be

Answer:

x = − 5, − 2

Step-by-step explanation:

x² + 7x + 10 = 0

x² + 5x + 2x + 10 = 0

x(x + 5) + 2 (x + 5) = 0

(x + 5)(x + 2) = 0

x = − 5, − 2

Answer:

Given the formula for a function, determine the domain and range.

Exclude from the domain any input values that result in division by zero.

Exclude from the domain any input values that have nonreal (or undefined) number outputs.

Use the valid input values to determine the range of the output values.

Answer:

first term is 6

Step-by-step explanation:

MULTIPLY BY 4

1) 6  (1st term)

2)     6x4 = 24    (24 is the second)

3)    24 x 4 = 96 (96 is the 3rd)

4) 96 x 4 = 384 (384 the 4th)

Answer:

$15.80

Step-by-step explanation:

Answer:

Step-by-step explanation:

x + 3x + 5x = 126

9x = 126

x = 14 (blue beads)

3(14) = 42 (purple beads)

5(14) = 70 (green beads)

The value of x must be 3, for quadrilateral WXYZ to be a parallelogram

The given parameters are:

[tex]\mathbf{CY = 3x + 2}[/tex]

[tex]\mathbf{WC = 2x + 5}[/tex]

From the question, we understand that:

Segments ZC and CX are congruent

This means that:

Segments WC and CY are congruent

So, we have:

[tex]\mathbf{WC = CY}[/tex]

This gives

[tex]\mathbf{3x +2 = 2x + 5}[/tex]

Collect like terms

[tex]\mathbf{3x + 2x =-2 + 5}[/tex]

[tex]\mathbf{x =3}[/tex]

Hence, the value of x must be 3, for quadrilateral WXYZ to be a parallelogram

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

[tex]C(t)=18,000\cdot(1-0.25)^t[/tex]

Operating:

[tex]C(t)=18,000\cdot 0.75^t[/tex]

At t=12 years, the price will be:

[tex]C(12)=18,000\cdot 0.75^{12}[/tex]

C(12)=$570.18

At t=20 years, the price will be:

[tex]C(20)=18,000\cdot 0.75^{20}[/tex]

C(20)=$57.08

"Your grade, g, must be at least  75 to pass this class'' is translated as:

Step-by-step explanation:

Given the grade is denoted by 'g'.

In algebra '≥︎' denotes that something must be 'greater than or equal to'. In other words, it means 'at least'.

As the gade must be at least 75, it means it can be greater than 75, but it can not be less than 75.

Therefore, "Your grade, g, must be at least  75 to pass this class'' is translated as:
