Mrrafil [7]

Answer:

y=-3,250t+25,000

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope of unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

Let

t ----> the number of years since 2011

y --->the car's value

In this problem the year 2011 represent t=0

so

the year 2015, represent t=4 years (2015-2011)

we have the ordered pairs

(0,25,000) ----> represent the y-intercept

(4,12,000)

<em>Find the slope m</em>

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{t2-t1}

substitute the values

m=\frac{12,000-25,000}{4-0}

m=\frac{-13,000}{4}

m=-\$3,250\ per\ year ---> is negative because is a decreasing function

we have

b=\$25,000 ----> value of y when the value of x is equal to zero (initial value)

substitute the given values

y=-3,250t+25,000

BM 1: 2. Find the value of angles x and y in circle A.<br> .X=<br> 150°<br> 175°<br> y =<br> to
Sladkaya [172]

Answer:

x = 35

y = 17.5

Step-by-step explanation:

By Central angle and its corresponding arc theorem:

x° = 360° - (175° + 150°)

x° = 360° - 325°

x° = 35°

x = 35

By inscribed angle theorem:

y \degree =  \frac{1}{2} x \\  \\ y\degree =   \frac{1}{2}  \times 35 \degree \\  \\ y\degree =  17.5 \degree \\  \\ y \:  = 17.5
