Solve the equation x/3-5=y for x
Annette [7]
X/3-5=y
add 5 to both sides
x/3=y+5
now multiply both sides by 3
x=3(y+5)
which means
x=3y+15

The student council sent its members on four field trips during the school year. The number of
Tanya [424]

Answer:

Since the number of buses needed to transport the members on each trip is a function of the number of members who went on each trip, then the independent variable(x) of the function is the number of members who went on each trip and the dependent variable (y) is the number needed. Then each point that represent the function has the form (x,y).

Then, the domain of the function is the set of values that can take the independent variable. In this case, x can take the values A =\{52,12,86,105\}, that is, A is the domain for this situation.

at 10a.m. you consume an energy drink containing 800mg of caffeine. if the half-life of caffeine is 5.7 hours, how much caffeine
icang [17]

Answer:

268 mg

Step-by-step explanation:

Let A₀ = the original amount of caffeine

The amount remaining after one half-life is ½A₀.

After two half-lives, the amount remaining is ½ ×½A₀ = (½)²A₀.

After three half-lives, the amount remaining is ½ ×(½)²A₀ = (½)³A₀.

We can write a general formula for the amount remaining:

A =A₀(½)ⁿ

where n is the number of half-lives .

n = t/t_½

Data:

  A₀ = 800 mg

    t₁ = 10 a.m.

   t₂ = 7 p.m.  

t_½ = 5.7 h

Calculations:

(a) Calculate t

t = t₂ - t₁ = 7 p.m. - 10 a.m. = 19:00 - 10:00 = 9:00 = 9.00 h

(b) Calculate n

n = 9.00/5.7 = 1.58

(b) Calculate A

A = 800 × (½)^1.58 = 800 × 0.334 = 268 mg

You will still have 268 mg of caffeine in your body at 10 p.m.

(5√2 - 1)^2<br> Steps please
faltersainse [42]

Answer:

51 - 10\sqrt{2}

Step-by-step explanation:

( 5\sqrt{2} - 1)² = (5\sqrt{2} - 1)(5\sqrt{2} - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

5\sqrt{2}(5\sqrt{2} - 1 ) - 1(5\sqrt{2} - 1 )

Distribute both parenthesis, noting that \sqrt{2} × \sqrt{2} = 2

= 50 - 5\sqrt{2} - 5\sqrt{2} + 1 ← collect like terms

= 51 - 10\sqrt{2}
