Answer:

y - 4 = -2(x - 5)

Step-by-step explanation:

point slope form is  y-y1 = m(x-x1)

the original equation is given in slope intercept form y = mx + b

Parallel lines have equal slopes so from the given equation  y = -2x-3

the slope m = -2.

Use the given point (5,4) as (x1, y1).

y - 4 = -2(x - 5)

Answer:

\displaystyle y - 4 = -2(x - 5)

Step-by-step explanation:

Parallel equations have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:

\displaystyle [5, 4] \\ \\ \boxed{y - 4 = -2(x - 5)}

**Remember, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so make sure both operation symbols are correct.

Riley buys office equipment with a total price of $6,280 for her new company. If the office equipment depreciates at a rate of 1
alexdok [17]

Answer: y = 6280(0.87)^x

Step-by-step explanation:

If the office equipment depreciates at a rate of 13% each year, then the rate of depreciation is exponential.

We would apply the formula for exponential decay which is expressed as

y = b(1 - r)^x

Where

y represents the value of the office equipment after t years.

x represents the number of years.

b represents the initial value of the office equipment.

r represents rate of decay.

From the information given,

y = $628

r = 13% = 13/100 = 0.13

Therefore, the equation that represents the value of the equipment after x years is

y = 6280(1 - 0.13)^x

y = 6280(0.87)^x

A stained glass window is going to be installed in a semi-circular opening, which is above a 30 inch wide door. If the stained g
xenn [34]
The answer is <span>$494.55</span>

Let's first imagine a circle and calculate its area and then reduce it in half for the area of a semi-circle. Since this opening is above <span>a 30-inch wide door, the circle will have a diameter of 30 inches.
The area of the circle (A) is:
A = </span>π · r²
where:
π = 3.14
r - radius: r = diameter ÷ 2 = 30 ÷ 2 = 15 inches

So, the area of the circle is:
A = π · r² = 3.14 · 15² = 706.5 inches²

The area of the semicircle is half of the area of the circle:
A1 = A ÷ 2 = 706.5 ÷ 2 = 353.25 inches²

Since  the stained glass window costs $1.40 <span>per square inch, for 353.25 square inches it will cost $494.55:
353.25 square inches * 1.40 $/square inch = $494.55</span>

What is the eighth term in the arithmetic sequence defined by the explicit formula
RideAnS [48]

Answer:

Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.

a_{n} = 2n + 7

To prove

As given the explicit formula for the arithmetic sequence .

a_{n} = 2n + 7

Put n = 8

a_{8} = 2\times 8 + 7

a_{8} = 16 + 7

a_{8} = 23

Therefore the eighth term in the arithmetic sequence is 23 .
