infinite solutions cause when you take out the 2 from the bottom equation, you get x + y = 4, which is the exact same equation as the first one, so literally any two values will result in the same for both

The answer would be $2.25

Step-by-step explanation:

If you multiply 2.25 with 5 you get 11.25 so now you just add the 7.50 to it and that's how you get 18.75

rewrite the equation 12x=13-x^2

Answers

Answer:

x^2+12x-13 = 0

Step-by-step explanation:

12x=13-x^2

=>12x+x^2=13-x^2+x^2

=>x^2+12x-13 = 13-13

=> x^2+12x-13 = 0

Answer:

x² + 12x - 13 = 0

Step-by-step explanation:

12x = 13 - x²

the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;

0 = 13 - x² - 12x

0 = -x² - 12x + 13

In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:

x² + 12x - 13 = 0

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"

Answers

Answer:

Future Value= $207,234.2

Step-by-step explanation:

Giving the following formula:

Initial value (PV)= $140,000

Appreciation rate (r)= 4% = 0.04

Number of years (n)= 10

To calculate the future value of the car after ten years, we need to use the following formula:

FV= PV*(1+i)^n

FV= 140,000*(1.04^10)

FV= $207,234.2
