Answer:

x = -3

Step-by-step explanation:

3х - 5 = 10 + 8x

Subtract 3x from each side

3х-3x - 5 = 10 + 8x-3x

-5 = 10+5x

Subtract 10 from each side

-5-10 = 10+5x -10

-15 = 5x

Divide each side by 5

-15/5= 5x/5

-3 =x

Well first of all, let's define what an integer is...

Integers are numbers such as -2, -1, 0, 1, 2 etc etc.

------

If f(5)=12,

f(6)=0.3*f(6-1)

= 0.3*f(5)

= 0.3*12

= 3/10 * 12

= 36/10

= 3.6

We now know that f(6)=3.6

Now:

f(7)=0.3*f(7-1)

= 0.3*f(6)

= 0.3*3.6

= (3/10) * (36/10)

= 108/100

= 1.08

Answer:

f(7)=1.08

MrRa [10]
When we solve for y, we want to isolate y by itself. To do so in this equation, we can divide both sides of the equation by 62...

y = 434/62 = 7
