Evaluate the expression

nadezda [96]

Answer:

Step-by-step explanation:

We are given the expression:

$\frac{-8(13-37)}{6}$

and asked to evaluate the expression.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve inside the parentheses first. Subtract 37 from 13.

⇒ 13-37= -24

$\frac{-8(-24 )}{6}$

Next, multiply -8 and -24.

⇒ -8*-24= 192

$\frac{192}{6}$

Finally. divide 192 by 6.

⇒ 192/6 = 32

$32$

When evaluated, the expression -8(13-37)/6 is equal to 32.

decided to purchase a new Toyota 4Runner for $25,635. you have promised your daughter that the SUV will be hers when the car is

Stella [2.4K]

Answer:

y = -3000x + 25,635

Step-by-step explanation:

well if the inital value of the car is $25,635 this means that when

x = 0 y = 25,635

(0 , 25635)

this will be our first point

Now if you tell us that in 1 year depreciate in value $3,000

this means thaw when

x = 1 y = 25,635 - 3,000

x = 1 y = 22,635

(1, 22635)

Now that we have 2 points we can have the equation

First we take the slope as follows

m = (y2 - y1) / (x2 - x1)

m = (22,635 - 25,635) / (1 - 0)

m = -3000 / 1

m = -3000

after calculating the slope we have to replace it in the following formula

(y - y1) = m (x - x1)

y - 25,635 = -3000 ( x - 0)

y - 25,635 = -3000x

y = -3000x + 25,635

Finally we replace the value of y by 10000

10,000 = -3000x + 25,635

10,000 - 25,635 = -3000x

-15,635 = -3000x

-15,635/-3000 = x

5.21167 = x years

These are the years it would take for the value to be 10,000

to know the days we simply multiply by 365

5.21167 * 365 = 1902.26 days
