6 0

Answer:

x = 3 x = -4

x = 1 x = 8

Step-by-step explanation:

x² + x - 12

(x + 4) (x - 3)

x + 4 = 0

x = - 4

-----------

x - 3 = 0

x = 3

x² - 9x + 8

(x - 8) (x - 1)

x - 8 = 0

x = 8

-----------

x - 1 = 0

x = 1

What multiplies to -26 and adds to -25
jeka57 [31]

Answer:

1 and -26

Step-by-step explanation:

Consider the factors of 26 (because the two numbers have to multiply to -26). These are: 1 and 26, 2 and 13.

2 and 13 cannot be added or subtracted from one another to get -25, but 1 and 26 can, or rather 1 and -26.

A limited edition poster increases in value each year with an initial value of $18. After one year and an increase of 15% per ye
USPshnik [31]

We have been given that a limited edition poster increases in value each year with an initial value of $18. After one year and an increase of 15% per year, the poster is worth $20.70.  

We will use exponential growth formula to find our required equation.

We know that an exponential function is in form y=a\cdot (1+r)^x, where

a = Initial value,

r = Growth rate in decimal form,    

x = Time.    

Let us convert 15% into percentage.

15\%=\frac{15}{100}=0.15

Initial value is 18.

Upon substituting these values in above formula, we will get:

y=18(1+0.15)^x

y=18(1.15)^x

Let us check our function by finding the value of poster after one year as:

y=18(1.15)^1

y=18(1.15)

y=20.70

Since the value of poster after 1 year matched with our findings, therefore, the equation y=18(1.15)^xcan be used to fund the value, y, after x years.
