Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used. He has another gift card for $145 that loses $3.50 for each 30-day period it is not used. Write an equation for the number of 30-day periods until the value of the gift cards will be equal. Let x represent the number of 30-day periods.
Answer:
x=20
Step-by-step explanation:
Let = a 30 day period
The first equation is 50 - 2x (because you start with $50 and subtract 2 for each 30 day period)
The second equation is 40-1.5x
Set them equal to each other: 50 - 2x = 40 - 1.5x
Solve for x:
50 - 2x = 40 - 1.5 x
+2x +2x
-----------------------
50 = 40 + 0.5 x
-40 -40
-------------------
10 = 0.5 x
20 = x
So there will be 20 30-day periods until the cards will be equal in value.
Check: After 20 periods, 50 - 2(20) = $10 left
40 - 1.5(20) = also $10 left

Answer: 11.) -6. 12.) 4/5
For the square roots, there should be a plus&minus sign but my keyboard doesn't have that.
13.) 3 14.) 8
explanation: For a square root, you are looking for a number that was multiplied by itself to become the number under the radical.
11 is a bit tricky since there is a negative sign before the radical. 6×6=36 -6 × -6 = 36. It seems they want only the -6 here.
4/5 ×4/5 = 16/25
For cube root, you need the number that is multiplied by itself three times. 3×3×3 = 27 8×8×8=512
On January 1st 2020 the populations of Japan and the Philippines were 126.5million and 109.6 respectively. Japan's population is currently decreasing by 0.2% per year while the population of the Philippines is increasing by 1.6% per year. If these rates of change remain constant, during which year will the two population be the same
In 422.5 years, the two populations will be the same
Let the year when the two populations will be the same be represented by x.
The equation to solve the question will be:
126.5 - 0.2x = 109.6 - 0.16x
Collect like terms
0.2x - 0.16x = 126.5 - 109.6
0.04x = 16.9
x = 16.9/0.04
x = 422.5
In conclusion, in 422.5 years, the two populations will be the same.

What is box plots?Box plots, also known as box-and-whisker plots, are a way to visualize the distribution of a set of numerical data.
To compare the shapes of the box plots, we need to look at the position of the median, the length of the box, and the length of the whiskers.
In the box plot for town A, the median is closer to the bottom of the box, indicating that the lower half of the data is more spread out than the upper half.
The whisker on the left side of the box plot is longer than the whisker on the right side, which indicates that there are some extreme values on the lower end of the data. This is consistent with a positively skewed distribution.
In contrast, the box plot for town B has a symmetrical box, with the median located near the center.
The whiskers on both sides of the box plot are roughly the same length, indicating that there are no extreme values on either end of the data. This is consistent with a symmetric distribution.
Thus, the correct option is D.

Grayson works in a department store selling clothing. He makes a guaranteed salary of $350 per week, but is paid a commision on top of his base salary equal to 20% of his total sales for the week. How much would Grayson make in a week in which he made $925 in sales? How much would Grayson make in a week if he made xx dollars in sales?
Answer: 535
0.20x+350
Step-by-step explanation:
If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here he makes a base income of $350 and he also earns 20% of his sales output and thus if he makes $925, his total income is
= 350+0.2×925
=$535
And let Grayson make x sales in one week then his salary will be
= 350+0.2x
Hence, If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

Maria's account has a credit of $ 13, and Harry's account has a debit of $ 14. Which of the following statements are true? Select that apply.
Select A Harry's account has $ 27 more than Maria's account. B Maria's account has $ 27 less than Harry's account. C Harry's account has $ 27 less than Maria's account. D Maria's account has $ 27 more than Harry's account.
PLEASE ANSWER FASTT!!
Answer:
A, Harry has $27 more.
Step-by-step explanation:
I could be wrong but.
1) debit cards are of your money, if you have $14 in your account it means you have $14 that you can spend without owing anything.
2) credit cards allow you to borrow money with the expectation that you pay it back. So if you have $13 of credit, you owe $13 which I guess could be seen as -$13.
3) the distance between -13 and 14 is 27.

Angle X and Y are supplementary. The measure of the angle X is 19° less than 2 times the measure of angle Y. What is the
measure of angle x?
Answer:
Supplementary angles add up to 180 degrees. The key phrase "less than" signifies you are going to subtract angle X from angle Y. Angle Y is 2 times the measure of angle X so you are going to multiply Y by 2. So right now you should have the equation 2y - 19 = 180. Then, plug it in. Add 19 to 180 to move it to the other side and then divide by 2.
Chose all the values of x that are not in the domain of this rational function. Picture attached, 15 points and I'll give Brainliest! Due in two hours. A. -2 B. 1 C. 2 D. o
Answer:
All of them.
Step-by-step explanation:
For rational functions, the domain is all real numbers except for the zeros of the denominator.
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:
[tex]x(x-1)(x^2-4)=0[/tex]
Zero Product Property:
[tex]x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0[/tex]
Solve for the x in each of the three equations. The first one is already solved. Thus:
[tex]x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2[/tex]
Thus, the values that cannot be in the domain of the rational function is:
[tex]x=-2,0,1,2[/tex]
Click all the options.
Answer:
[tex]\Large \boxed{\mathrm{All \ options}}[/tex]
Step-by-step explanation:
The domain of a function are all possible values for x.
To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are not included in the domain, since the denominator of 0 would make the rational function undefined.
[tex]x(x-1)(x^2-4)=0[/tex]
Setting the factors equal to 0.
[tex]x=0 \\ \\ \\\\ x-1=0 \\ \\ x=1 \\ \\ \\ \\ x^2 -4=0 \\ \\ x^2 =4 \\ \\ x=\pm 2[/tex]
The values of x that are not in the domain of the rational function are x=-2, x=1, x=2, and x=0.
From the set {1, 2, 3, 4, 5}, find the lowest value of x that makes each inequality true. Arrange the inequalities in increasing order of the lowest value of x from the set that makes them true. 5x − 3x > 9 2x − 1 > 0 x + (x − 1) > 5
2x - 1 > 0 ( x = 1)
x + (x − 1) > 5 ( x = 3)
5x − 3x > 9 ( x = 5)
Answer:
2x - 1 > 0 ( x = 1)
x + (x − 1) > 5 ( x = 3)
5x − 3x > 9 ( x = 5)Step-by-step explanation:

It is required to find the another name for line P.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
To answer this type of problem we have to know the axiom.
At least two points define a line.
Then I can call line p as (see below attached picture)
The line p cuts the 2 different points , point C and point D, so we can.t indicate a line in a single letter of the Western Alphabet.
Therefore, the another name for line P is line [tex]\over (CD)[/tex].
