When the variable is on both sides of the equation, it must be isolated on one side, and it doesn't matter which

Answer:

The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number.

the soccer league needs to transport all 133 players to the tournament. If 4 players can ride in one car, how many cars are need

LenKa [72]

Take the 133 players and divide by 4.

(133 / 4) = 33.25

33 cars can carry (33 x 4) = 132 players.
But that leaves one player out in the cold with no ride.
You need one more car ... 34 cars all together.

Find a and b so that f(x) = x^3 + ax^2 + b will have a critical point at (2,3).

Digiron [165]

Using the critical point concept, it is found that a = -3 and b = 7.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

$f^{\prime}(x) = 0$

In this problem, the function is:

$f(x) = x^3 + ax^2 + b$

Hence, the derivative is:

$f^{\prime}(x) = 3x^2 + 2ax$

Then:

$f^{\prime}(x) = 0$

$3x^2 + 2ax = 0$

$x(3x + 2a) = 0$

$x = 0$

$3x + 2a = 0$

$3x = -2a$

$x = -\frac{2a}{3}$

Since the critical point is at x = 2, we have that:

$-\frac{2a}{3} = 2$

$-2a = 6$

$2a = -6$

$a = -3$

Then:

$f(x) = x^3 - 3x^2 + b$

Critical point at (2,3) means that when $x = 2, y = 3$ , then:

$3 = 2^3 - 3(2)^2 + b$

$8 - 12 + b = 3$

$b = 7$

Find three consecutive numbers whose sum is 84

mrs_skeptik [129]

Answer:

27 28 29

Step-by-step explanation:

Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.

n+(n+1)+(n+2)=84.

3n+3=84.

⇒3n=81.

⇒n=27.

Hence numbers are n,n+1,n+2→27,28 and 29

What 1 7/8 × 2 3/8 will be equal to,greater than or less than 2 3/8

Sunny_sXe [5.5K]

Answer:

greater than

Step-by-step explanation:

Since 2 $\frac{3}{8}$ is being multiplied by a number greater than 1, the result will be greater than 2 $\frac{3}{8}$

If the multiplier was 1 then the result would be equal to 2 $\frac{3}{8}$

If the multiplier was between 0 and 1 the result would be less than 2 $\frac{3}{8}$
