Answer:

  multiply their coefficients, use the base with the sum of exponents

Step-by-step explanation:

The coefficients multiply. The base gets an exponent that is the sum of the exponents of the factors.

  (a·x^b)(c·x^d) = ac·x^(b+d)

_____

If you remember that an exponent is simply an indicator of the number of times the base is a factor, this should be fairly clear. The usual associative and commutative properties of multiplication apply.

Example

  5x^2 · 7x^3= 5·x·x·7·x·x·x

  = 5·7·x·x·x·x·x

  = (5·7)(x^(2+3))

  = 35x^5

Answer: $30.92

Step-by-step explanation:

First step is to turn 5% into a decimal so that you can use it easier in a math sentence -- 0.05

Next, find out what 5% of $32.55 is by multiplying

0.05 x 32.55

= 1.6275

Round to the nearest cent because we don't use anything smaller than a cent when we are talking about money.

= $1.63

This is the amount of tax included in the price of $32.55

If we want to know what it the book cost before tax we simply take the tax off.

$32.55 - $1.63

= $30.92

Hope that helps :)

Answer:

61 cabins

Step-by-step explanation:

Since Jim skipped 15 cabins and ended up sitting in cabin 2 that means he finished the number of cabins available and passed it by 2 cabins. Meaning that if we subtract 2 cabins from the 15 he skipped that would mean that from where Jack is sitting there are only 13 more cabins available. Now we simply add the 13 cabins to the number of cabins that Jack is sitting in to calculate the total number of cabins.

48 + 13 = 61

Step-by-step explanation:

62 cabins. Jack is skipping the next 15 cabins, so, in reality, you are adding 14 to 48.

Hello!

[tex]\large\boxed{x = 17}[/tex]

[tex]\sqrt{x -1} + 5 = 9[/tex]

Begin by subtracting 5 from both sides:

[tex]\sqrt{x -1} = 9 - 5\\\\\sqrt{x -1} = 4[/tex]

Square both sides to get rid of the radical:

[tex]x - 1 = 16[/tex]

Add 1 to both sides to completely isolate for x:

[tex]x = 17[/tex]

Answer:

each balloon costs 1$ and each banner costs 3$

Step-by-step explanation:

The costs of each balloon and banner are $1 and $3 respectively.

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.

Let x represents balloons and y represents banners.

Establishing the equations,

x+y = 4

x = 4 - y......(i)

3x + 2y = 9...(ii)

Put eq(i) in eq(ii)

3(4 - y) + 2y = 9

12 - 3y + 2y = 9

y = 3

Put y = 3 in eq(i)

x = 4-3

x = 1

Hence, the costs of each balloon and banner are $1 and $3 respectively.

Answer:

42+14         answer is 56

Step-by-step explanation:

Answer:

Ok so I’m stuck with this question too But I got the top part.

p=1/6

q=2/6

r=3/6

s=3/6

A) The probabilities placed at P, Q, R and S on the tree diagram are;

P = 1/6; Q = 1/3; R = 1/4; S = 1/4

B) The probabilities of her winning or losing is;

Probability that she will win = 5/12

Probability that she will lose = 7/12

At point P; Only 1 is rolled.

Since there are 6 possible numbers, then Probability at P = 1/6

At point Q; either 2 or 3 can be rolled.

Since there are 6 possible numbers, then Probability at Q = 2/6 = 1/3

At point R; 4,5, or 6 can be rolled on first roll.

Thus, Probability on first roll = 3/6

At R on second roll if she gets even, probability on second roll = 3/6

At S on second roll if she gets odd, probability on second roll = 3/6

Thus;

Overall probability at R = 3/6 × 3/6 = 1/4

Overall probability at S = 3/6 × 3/6 = 1/4

Thus, probability that she will win = 1/6 + 1/4 = 5/12

Probability that she will lose are the probabilities at Q and S.

Probability that she will lose = 1/3 + 1/4 = 7/12

Answer:

y is equal to nine and two thirds, or 9.666...

Step-by-step explanation:

To solve this, we first need to know the value of x.  We can see though that x + (x - 12) is equal to 180 degrees, so:

x + 5x - 12 = 180

6x = 192

x = 32

Now that we have x, we can use the same rule to solve for y:

3y - 8 = x

3y - 8 = 32

3y = 40

y = 40 / 3

So y = 40/3, or 9 and 2/3

Bonus:

I almost wonder if the question was printed incorrectly, as the answer would have been a nice tidy integer if the other corner was 3y + 8 instead of 3y - 8.

If that were the case we'd have:

3y + 8 = 32

3y = 24

y = 8

A nice clean answer

To be clear, this last bit is NOT the correct answer, just an observation. If the book tells you that eight is the answer, then the question is misprinted.

The correct sequence of transformations takes A to its image A' is,

⇒ A translation 1 unit down followed by a reflection in the x-axis.

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

We have to given that;

The sequence of transformations takes A to its image A'.

Now, We have;

The coordinate of A are (4, 5)

And, The coordinate of A' are (4, - 4)

Hence, The correct sequence of transformations takes A to its image A' is,
