Evaluate b(x)=5x-5/3x-16

Answer:

17

Step-by-step explanation:

68/4=17

68 is the total perimeter, to get the length of each side is divide by 4, because it's a square, it has 4 sides.

Hope this helps!

Answer:

68 is the length of each side

Answer:

There are no solutions

Step-by-step explanation:

Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.

Given:

Consider the height  of the water balloon over  time can be modeled by the  function

[tex]y=-16x^2+160x+50[/tex]

To find:

The maximum height of the water balloon  after it was thrown.

Solution:

We have,

[tex]y=-16x^2+160x+50[/tex]

Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.

If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then

[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]

Here, [tex]a=-16,b=160,c=50[/tex]. So,

[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]

[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]

[tex]-\dfrac{b}{2a}=5[/tex]

Now, put x=5 in the given equation.

[tex]y=-16(5)^2+160(5)+50[/tex]

[tex]y=-16(25)+800+50[/tex]

[tex]y=-400+850[/tex]

[tex]y=450[/tex]

The vertex of the given parabolic equation is (5,450).

Therefore, the maximum height of the balloon is 450 units after 5 units of time.

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:

✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:

✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:

✺ Add 2 to both sides:

✺ Add 3 and 2 to get 5:

✺ Divide both sides by 5. Since 5 is positive, the inequality direction remains the same:

✺ Divide 5 by 5 to get 1:

✺  So your answer is B, [tex]\boxed{x<1}[/tex].

Answer:

[tex]\boxed {x < 1}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]-9 < -3(5x - 2)[/tex]

-When you are dividing an integer by a negative integer, then the inequality sign changes. So, divide both sides by [tex]-3[/tex]:

[tex]\frac{-9}{-3} < \frac{-3}{-3} + 5x - 2[/tex]

[tex]3 > 5x - 2[/tex]

-Switch sides:

[tex]5x - 2 < 3[/tex]

-Add [tex]2[/tex] to both sides:

[tex]5x - 2 + 2 = 3 + 2[/tex]

[tex]5x < 5[/tex]

-Divide both sides by [tex]5[/tex]:

[tex]\frac{5x}{5} < \frac{5}{5}[/tex]

[tex]\boxed {x < 1}[/tex]

Answer:

First add all the equations like (11y-32)+(3x-16)+(6x+7)=180

Step-by-step explanation:

You would first combine all the like terms so put all the variables on one side and the numbers on the other. After you have done that, you would just solve.

Answer: 1.26 inches

explanation :

because if you subtract 7 by 3.2 you'll get

3.8, 3.8 will be the total of rain if you add week 1 2 4 , then youll have to find the average by dividing 3.8 by 3 youll get 1.26 . so that means the average lenth of the rain for 1 2 4 is 1.26 inches

Given :

A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.

To Find :

The length of the frame.

Solution :

We know, perimeter of the rectangle is given by :

[tex]P=2(l+b)\\\\P=2(3x+x)\\\\P=8x[/tex]

Now, it is given that 18 feet of wood is used.

So,

[tex]8x=18\\\\x = 2.25\ feet[/tex]

Therefore, length of frame is given by  3x = 6.75 feet.

Hence, this is the required solution.

Answer: A, 6.75

Step-by-step explanation: If the frame is 3 times the width and Kyle uses 18 feet them this the only correct option out of the other 3.

A. Multiply both sides of the equation by 10.

SInce 10 is being divided with s, weneed to isolate it. To do this multiply 10 on both sides.

Answer: {x,y}={6,21}

Step-by-step explanation:

// Solve equation [2] for the variable  x

  [2]    3x = 18

  [2]    x = 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(6) - y = -9

  [1]     - y = -21

// Solve equation [1] for the variable  y

  [1]    y = 21

// By now we know this much :

   x = 6

   y = 21

We are done

Answer:

y = 2x -6. A dependent system, so all numbers on this line.

Step-by-step explanation:

2x - y = 6

-3y = -6x + 18

In order to solve a system of equations, you want to get isolate y. One equation already has done that for us, so that makes it easier.

2x - y = 6

In order to isolate y in this equation, you must simply subtract 2x from both sides, which would give us:

-y = -2x + 6

Now, you can't leave y negative. Normally you'd divide the y by its variable, but this one doesn't have a variable. so you must divide both sides by -1.

[tex]\frac{-y}{-1} =\frac{-2x+6}{-1}[/tex]

We divide both sides because what you do to one side you must do to the other. This leaves us with the equation:

y = 2x - 6

Now, for the other equation. It's simple since y is already isolated.

-3y = -6x + 18

Once again we will be dividing both sides, but this time it's by -3.

[tex]\frac{-3y}{-3} =\frac{-6x+18}{-3}[/tex]

We are dividing by -3 instead of -1 because y in this equation has a variable of -3. This would give us:

y = 2x - 6

Now, normally in order to get the answer, you must graph both of these equations, but since these equations ended up being the same, the answer is every number that appears on the line. This is called a dependent system.

Answer: For 5 pirate ships, you need 55 pirates. For 11 pirate ships, you need 121 pirates.

Step-by-step explanation:

22 (# of pirates) divided by 2 (# of ships) = 11 pirates per ship. Use this knowledge of 11 pirates per ship to find how many pirates you need for different numbers of ships:

  11*5= 55 for 5 ships &

11*11= 121 pirates for 11 ships.

Answer:

(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125

Step-by-step explanation:

630 ÷ 7 ÷ 2 ⋅ 9 ⋅ 25 = 125

(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125

         90 ÷ 18 ⋅ 25 = 125

           5 ⋅ 25 = 125

               125 = 125

Answer:

It is not the same

Step-by-step explanation:

Is 5/2 greater than 2/5? Is 5/2 bigger than 2/5? Is 5/2 larger than 2/5? These are all the same questions with one answer.

When comparing fractions such as 5/2 and 2/5, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.        

  To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below: 5/2 = 2.5

2/5 = 0.4 Therefore, 5/2 is greater than 2/5 and the answer to the question "Is 5/2 greater than 2/5?" is yes.

Step-by-step

Its different because 5:2 and 2:5 (or 5/2 and 2/5) have different numerators and denominators.

Answer:

$42.49

Step-by-step explanation:

This means the cost of the item to you is $42.49. You will pay $42.49 for a item with original price of $49.99 when discounted 15%. In this example, if you buy an item at $49.99 with 15% discount, you will pay 49.99 - 7.4985 = 42.49 dollars.

Answer:

42.49

Step-by-step explanation:

Discount = 15% of 49.99

              = 0.15 * 49.99

              = 7.4985

Cost after discount = 49. 99 - 7.4985

                               = 42.4915

                               = 42.49

Answer:

Two students can make maximum 36 treat bags.

Number of pieces of silly Bandz in each bag [tex]=1[/tex]

Number of pieces of Double Bubble in each bag [tex]=2[/tex]

Step-by-step explanation:

Number of pieces of silly Bandz = 36

Number of pieces of Double Bubble = 72

To find greatest number of treat bags that they can make, find H.C.F. of 36 and 72

[tex]36=(2^2)(3^2)\\72=(2^3)(3^2)[/tex]

[tex]H.C.F(36,72)=36[/tex]

So,

they can make maximum 36 treat bags.

Number of pieces of silly Bandz in each bag [tex]=\frac{36}{36}=1[/tex]

Number of pieces of Double Bubble in each bag [tex]=\frac{72}{36}=2[/tex]
