       ➣ Answer: \boxed{\bold{x=-3098}}

↔↔↔↔↔↔↔↔

Explanation: ↓↓↓↓↓

↔↔↔↔↔↔↔↔

       ➤ [ Step One ] Switch Sides

\bold{x+5^5=3^3}

       ➤ [ Step Two ] Simplify: \bold{5^5=3125}

\bold{x+3125=3^3}

       ➤ [ Step Three ] Simplify: \bold{3^3=27}

\bold{x+3125=27}

       ➤ [ Step Four ] Subtract 3125 From Both Sides

\bold{x+3125-3125=27-3125}

       ➤ [ Step Five ] Simplify

\bold{x=-3098}

Which set is a function?
Sonja [21]
B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)

long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.

second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6
hope i helped! if i did please give me brainlest :)

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The
frosja888 [35]

Answer:

Step-by-step explanation:

Joint variation has the equation

y = kxz

k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else.  We are given y = amount of oil used, x = distance traveled, z-squared is the speed.  Our equation looks like this, to be exact:

y=kxz^2

Filling in with the initial conditions:

34=k(60)(20)^2 which gives us the

k = .0014166667

Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

y=(.0014166667)(32)(23)^2

which gives us that the amount of oil used, when rounded to the tenths,

y = 24.0 barrels

R/3+2=21 solve for r
olchik [2.2K]

Answer:

r=63

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    r/3-(21)=0             r

Simplify   —

           3

r    

 — -  21  = 0

 3     2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         21     21 • 3

   21 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

A sequence of 7 numbers starts with 8. The second number in the sequence is unknown and may be positive or negative. The third t
scoray [572]

Answer:

4

Explanation:

a_1=8,a_7=0

Since the third term is the sum of the two previous terms

a_3=a_2+a_1

a_7=a_6+a_5

a_7=a_5+a_4+a_4+a_3

Continuing in like manner

a_7=5a_3+3a_2

Since a_3=a_2+a_1

a_7=5(a_2+a_1+3a_2

a_7=5a_2+5a_1+3a_2

a_7=8a_2+5a_1

Recall: a_1=8,a_7=0

0=8a_2+5*8

8a_2=-40

a_2=-5

The sequence is therefore:

8,-5,3,-2,1,-1,0

The sum of the seven numbers is 4.
