Answer:

[tex]y = \frac{-2}{3}[/tex]

Step-by-step explanation:

[tex]f(x)=-1[/tex], means thsat you replace all the x with -1. Then after you replace it you simplify the fraction.

[tex]f(x)=-1[/tex]

Equation: [tex]f(x) = \frac{x-1}{3}[/tex]

Steps:

1. [tex]f(-1)= \frac{(-1)-1}{3}[/tex]

2. [tex]f(-1)= \frac{-2}{3}[/tex]

Answer:

[tex]f(-1)= \frac{-2}{3}[/tex]

Answer:y=-2/3

Step-by-step explanation:

From factoring, the volume of a rectangular prism can be written as:

3x * (2x+1) * (3x-2).

In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization.  One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.

The question gives: 18x³-3x²-6x. You can see that, initially, 3x is a common term. Therefore, you can write: 3x * (6x²-x-6) . Nonetheless, the question also asks 3 linear expressions, here only you have one (3x).

Thus, you should factor the expression (6x²-x-6) into two linear expressions: (2x+1)* ( 3x-2).

Thus, the volume of a rectangular prism can be written as:

3x * (2x+1) * (3x-2)

Answer:

See below ~

Step-by-step explanation:

(a) Mean of the data

(b) New mean after each data point increased by 10

(c) New mean after each data point doubled [from (b)]

Answer:

a) 1.8

b) 11.8

c) 23.6

mean: sum of numbers/total numbers

⇒ mean: (2.4+1.6+3.2+0.3+1.6)/5 ⇒ 9/5 ⇒  1.8

If all the data's are increased by 10

{12.4, 11.6, 13.2, 10.3, 11.5}

Then mean ⇒ (12.4+11.6+13.2+10.3+11.5)/5 ⇒ 11.8

if the new data doubled, the mean will be double

11.8 * 2 = 23.6

Answer:

For 36 hours, that would be 792 quarts. The unit rate is 528 quarts per day.

Step-by-step explanation:

If you divide 36 by 10, you get 3.6, and then you multiply that with 220. That gets you 792 quarts for 36 hours. To find out the rate per day, do 24 divided by 10, and then multiply that by 220.

Answer:

x=110lbs and y=120lbs

Step-by-step explanation:

[tex]Solution,\\\\x+y=230lbs\\\\[/tex]

When the weight of x is 10lbs less than y,

Then,

[tex]x=y-10lbs[/tex]

Now we have,

[tex]\hookrightarrow x+y=230lbs\\\\\hookrightarrow (y-10lbs)+y=230lbs\\\\\hookrightarrow 2y-10lbs=230lbs\\\\\hookrightarrow 2y=230lbs+10lbs\\\\\hookrightarrow 2y=240lbs\\\\\hookrightarrow y=240lbs/2\\\\\hookrightarrow y=120lbs[/tex]

Again,

As x=y-10lbs

Then,

[tex]\hookrightarrow x=y-10lbs\\\\\hookrightarrow x=120lbs-10lbs\\\\\hookrightarrow x=110lbs[/tex]

The answers to your questions are as we have them below:

a.   s ( 2 burgers + 1soda )

b.  s ( $16.00 + $2.50) ≤ $100

c. The maximum number of sodas that can be purchased is 5.40 sodas

An algebraic expression is an expression containing integer constants, variables and algebraic operations

Detailed solution of the above is given below:

One Burger costs $8.00

One soda costs $2.50

Combined = s (2burgers + 1soda)

where s is the number of persons ordering.

a.   s ( 2 * $8.00 + $2.50 )

     s ( $16.00 + $2.50) = s($18.50) assuming that the hotdogs will be the total amount to be spent

b. if the cant spend more than a $100 gift card, the inequality will be

 s ( $16.00 + $2.50) ≤ $100

 s($18.50)   ≤ $100

 s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40

Therefore the number of burgers and soda they can buy is

5.40 (2burgers + 1soda) = 10.80 burgers and 5.40sodas

c.  s ( $16.00 + $2.50) ≤ $100

 s($18.50)   ≤ $100

 s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40

The maximum number of sodas that can be purchased is 5.40 sodas

In conclusion, the algebraic expression for the orders you and your friends will make combined is:  s ( 2 burgers + 1soda )

Step-by-step explanation:

180-98 = 82

They are supplementary and make 180 in total so x is 82

If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

The root of the polynomial function is given as:

-3 + i

The above root is a complex root.

If a polynomial has a complex root, then the conjugate of the root is also a root of the function

The conjugate of -3 + i is -3 - i

Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

Answer:

Step-by-step explanation:

The vertex form of the provided equation  y = (x 3)2 (x 4)2 is expressed as  (x+3.5)²+0.5.

Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.

The standard equation of the vertex form of parabola is given as,

y=a(x-h)^2+k

Here, (h, k) is the vertex point.

The given equation is

[tex]y = (x +3)^2 +(x+ 4)^2\\y=x^2+9+6x+x^2+16+8x\\y=2x^2+14x+25[/tex]

To convert this equation, into the vertex form, follow the following steps,

[tex]y=2(x^2+7x+12.5)\\y=2((x+3.5)^2-12.25+12.5)\\y=(x+3.5)^2+0.5[/tex]

Thus, the vertex form of the provided equation  y = (x 3)2 (x 4)2 is expressed as  (x+3.5)²+0.5.

Answer: 48 yards

Step-by-step explanation:

Answer: 48 yd

Step-by-step explanation:

when trying to find one leg of a triangle given the other two, a^2 +b^2 = c^2 is applicable. A representing the first leg, B representing the second, and C representing the hypotenouse (a and b are interchangeable). So,

formula: a^2 + b^2 = c^2

insert given: 20^2 + b^2 = 52^2

exponents: 400 + b^2 = 2704

subtract: b^2 = 2704 - 400

simplify: b^2 = 2304

square root of both sides: b = [tex]\sqrt{2304}[/tex]

answer: b = 48

The size of the sample space is 8.

The probability that it has a letter that immediately follows an odd number is 1/2.

There is no probability that D is in the code but not in the first position.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The size of the sample space is the number of ways to choose one letter and two numbers, without repetition.

We can choose the letter in 4 ways, the first number in 2 ways, and the second number in 1 way (since we can't repeat a number), giving a total of 4 x 2 x 1 = 8 possible codes.

Let's list all the possible codes: 5A6, 5B6, 5C6, 5D6, 56A, 56B, 56C, 56D

The probability that a code has a letter that immediately follows an odd number:

We need to count the number of codes that have a letter following an odd number.

From the list above, we see that the codes 5B6, 5D6, 56B, and 56D have a letter following an odd number.

Therefore, there are four favorable outcomes out of eight possible outcomes.

So the probability is 4/8 = 1/2.

The Probability that D is in the code but not in the first position:

D can be in the second or third position.

If D is in the second position, there are 3 ways to choose the first digit (since we can't use D, and we can't repeat the first digit), and 1 way to choose the third digit, giving a total of 3 * 1 = 3 codes.

If D is in the third position, there are 3 ways to choose the first digit and 2 ways to choose the second digit (since we can't repeat any digit), giving a total of 3 x 2 = 6 codes.

So there are 3 + 6 = 9 favorable outcomes out of 8 possible outcomes (since there are 8 possible codes in total).

Therefore, the probability is 9/8, which is greater than 1.

This is not possible, so the answer is that there is no probability that D is in the code but not in the first position.

Thus,

The size of the sample space is 8.

The probability that it has a letter that immediately follows an odd number is 1/2.

There is no probability that D is in the code but not in the first position.
