What is distributive property of algebraic expression?
At first it is important to know about algebraic expression.
Algebraic expression consists of variables and numbers connected with addition, subtraction, multiplication and division.
Distributive property is a property which connects both addition and multiplication.
Suppose a, b and c are three numbers. Distributive property implies
a [tex]\times[/tex] (b + c) = a [tex]\times[/tex] b + a [tex]\times[/tex] c
Here,
y(6 + 15)
y [tex]\times[/tex] (6 + 15)
6 [tex]\times[/tex] y + 15 [tex]\times[/tex] y
6y + 15y
21y
This is the required equivalent expression

The image of the point P(x, y) = (4, 2) by means of a translation formula is point P'(x, y) = (- 1, 4).
What is the image of a given point after making a translation?
In this question we find the coordinates of a point set on Cartesian plane which is modified by using a translation, a kind of rigid transformation. Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved.
Vectorially speaking, translations are described by the following formula:
P'(x, y) = P(x, y) + T(x, y)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vectorIf we know that P(x, y) = (- 9, - 3) and P'(x, y) = (- 14, - 1), then the translation vector is:
T(x, y) = P'(x, y) - P(x, y)
T(x, y) = (- 14, - 1) - (- 9, - 3)
T(x, y) = (- 5, 2)
Then, the image of the point (4, 2) is:
P'(x, y) = (4, 2) + (- 5, 2)
P'(x, y) = (- 1, 4)
The image of the point (4, 2) by using a translation formula is (- 1, 4).

What is probability ?Probability is a branch of mathematics that deals with calculating the probability of a given event, expressed as a number between 1 and 0. An event with a probability of 1 can be considered certain: for example, the probability of a coin toss. a toss that results in either "heads" or "tails" is 1 because there are no other options, assuming the coin lands flat. An event with probability 0.5 can be considered equally likely to occur or not to occur: for example, the probability that a coin toss results in heads is 0.5, because the toss is equally likely to result in tails." An event with probability 0 can be considered impossible: for example, the probability that the a coin lands (uniformly) without both sides up is 0, because either "heads" or "tails" must be up.

Mars is 142 million miles from the Sun. About how many seconds will it takefor light to travel from the Sun to Mars?A. 235 secondsB. 327 secondsC. 642 secondsD. 763 seconds
D. 763 seconds
Explanation:
Data:
Seconds light travels distance between Sun and Earth : 500 seconds
Distance between Sun and Earth: 93 million miles
Distance between Sun and Mars: 142 million miles
Formula: (see image below)
Solution:
From Sun to Mars the light takes (142 * 500) / 93 = 763 seconds
NB:
The tactic is to first put the data given in a table like in the image above, to first multiply diagonally then divide horizontally. (starting from the data that his paired data).
Here the paired data missing is the time it takes for the light to travel from the Sun to Mars, therefore you'll multiply the distance between the Sun to Mars (known data missing a pair) by the time it takes light to travel from the Sun to Earth (known data with its pair), then divide the result by the distance between the Sun and earth (pair of the former mentioned known data)

F.
Inequality: 4x + 8 < 28
The inequality that represents the equation is 8x+4<=28. The money spent on each cup is $3 or less. So, B and D are the correct options
Number of cups ordered by Kara = 8 cups
Money spent on the child's meal by Kara = $4
Total money with Kara = $28
Let x represent the money Kara will spend on each cup of soup
In formulation of the equation we get the following:
Number of cups*Money she can spend on each cup + Money spent on child's meal <= 28
8x + 4<=28
Solving the inequality:
8x<=24
x<= $3
So, the cost of a cup is $3 or less

Part A: -5/9, 6/10, -7/11, 8/12
Part B:
[tex]f(n)=(-1)^{n}(\frac{n}{n+4})[/tex]Part C: Positive
Explanation:The given sequence is:
[tex]-\frac{1}{5},\frac{2}{6},-\frac{3}{7},\frac{4}{8},....[/tex]As seen above the sequence is an alternating sequence because it changes in sign
Also, neglecting the sign chnages, we will observe, a common diffference of 1 in the numerator and denominator
a) Therefore, if the pattern continues, the next 4 terms in the sequence are:
-5/9, 6/10, -7/11, 8/12
b)
Without the sign, the explicit equation representing the numerator is calculated below:
1, 2, 3, 4......
The first term, a = 1
The common difference, d = 1
This is an arithmetic sequence
N(n) = a + (n - 1)d
N(n) = 1 + (n - 1)(1)
N(n) = 1 + n - 1
N(n) = n
The explicit equation representing the denominator is calculated below
5, 6, 7, 8........
The first term, a = 5
The common difference, d = 1
D(n) = a + (n - 1)d
D(n) = 5 + (n - 1)(1)
D(n) = 5 + n - 1
D(n) = n + 4
The alternating sequence will include the term below:
[tex](-1)^n[/tex]Therefore, the explicit equation for f(n) representing the sequence is:
[tex]f(n)=(-1)^n(\frac{n}{n+4})[/tex]Part C) The sign of f(56) will be:
(-1)^56 = 1
Since this gives us a positive value, the sign of f(56) is positive

Write an equation describing x as a function of y
The amount Lins sister earns at her part-time job is proportional to the number of hours she works.
She earns 9.60 dollars per hour.
1. Write an equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.
$9.60 per hour means that y = 9.60 and x = 1
[tex]\begin{gathered} y=kx \\ 9.60=k(1) \\ k=\frac{9.60}{1} \\ k=9.60 \end{gathered}[/tex]Since we found the value of constant k, so the relation becomes
[tex]y=9.60x[/tex]2. is y a function of x? explain how you know
y is a function of x means that the value of y depends on the value of x.
In the above function, when the value of x changes then the value of y will also change.
3. Write an equation describing x as a function of y
To write the equation describing x as a function of y, make x the subject of the equation.
This simply means to separate out the variable x.

From the z score values shown below:
The z scores of the value are
[tex]\begin{gathered} z_1=-1.28 \\ z_2=1.28 \end{gathered}[/tex]Thus,
[tex]\begin{gathered} \text{when z=-1.28, we have} \\ -1.28=\frac{x-3.7}{0.91}\text{ } \\ \Rightarrow x=2.5352 \\ \text{when z=1.28, we have} \\ 1.28=\frac{x-3.7}{0.91} \\ \Rightarrow x=4.8648 \end{gathered}[/tex]Thus, the two values for which the middle 80% of scores lie are 2.5 and 4.86.
