Subtract (5y3 + 6y + 3y4) from (4y4 - 8y3).

A) y4 - 13y3 - 6y
B) y4 - 13y3 + 6y
C) 9y4 -13y3 - 6y
D) y4 + 13y 3 - 6y

A) y ^4 −  13 y^ 3  −  6 y

Step-by-step explanation:

     4y^4 - 8y^3

-    5y^3 + 6y + 3y^4

flip the equations around

  -8y^3 + 4y^4

-   5y^3 + 6y + 3y^4

-13y^3 - 6y + y^4

Rearrange to get:

y^4 - 13y^3 - 6y

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
