First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C

What is 215% of 44? 9460 946 94.6 9.46
nirvana33 [79]

Answer:

94.6

Step-by-step explanation:

     100% of 44 = 44

⇒  200% of 44 = 44 + 44 = 88

   15% = 15/100 = 0.15

⇒ 15% of 44 = 0.15 x 44 = 6.6

Therefore, 215% of 44 = 88 + 6.6 = 94.6

Kwame bought a car for $25,000. The value of the car is decreasing at a rate of 6.5% each year. Write a function that represents
sweet-ann [11.9K]
<h3><u>The function that represents the price P of the car after x years is:</u></h3>

P = 25000(0.935)^x

<em><u>Solution:</u></em>

<em><u>The decreasing function is given as:</u></em>

y = a(1 - r)^t

Where,

y is future value

a is initial value

r is decreasing rate in decimal

t is time period

From given,

a = 25000

r = 6.5 \% = \frac{6.5}{100} = 0.065

number of years = x

future value = P

Therefore,

P = 25000(1 - 0.065)^x\\\\P = 25000(0.935)^x

Thus the function is found
