Timothy began the week with $35.He bought lunch at school,paying $2.25 for each meal. Let x be the number of meals he bought at school and y be the amount of money he had left for the end of the week. Which equation can represent the relationship in the sitiountaion?

The equation of the parabola with focus at (0,-2) and directrix at y=2, which opens downward, is y = -1/16x².

To find the equation of the parabola with focus at (0,-2) and directrix at y=2, we recall that a parabola is the set of all points equidistant from a point called the focus and a line called the directrix. Since the focus is below the directrix and on the y-axis, this parabola opens downwards.

Steps to Find the Parabola's Equation

Calculate the distance p between the focus and directrix, which is the absolute value of the y-coordinate of the focus minus the y-coordinate of the directrix. Here, p = 2 - (-2) = 4.

You can do the same thing with a program called Desmos. Using this program, I've put A and B (the graphs) in Desmos and attached it to this Answer.

You could just do the same with your graphing calculator if you have one.

The problem is that my graphing calculator won't draw the blue line which is x = - 2

So go to Desmos and put in 2 graphs. the first one is y = - 1/2 x + 3 in red

The second is x =- 2. These are entered on the left of Desmos.

The blue line is x = - 2. You notice that the intersect point is (-2,4). Run your finger straight across until you hit 4. That's all you have to do for the A part.

B

The question has 3 blanks. The first 2 come from the question directions to see if you read those directions. Always a good idea to do that.

first blank  is x = - 2

second blank is x = - 2

Third blank is - 7

The red line is y = 3/2 x - 4

The blue line is x = -2

Any person who is 55 inches or taller can go on the carnival ride. This is an inference made using inequalities in Mathematics. For instance, if one person is 58 inches tall and another is 52 inches tall, only the person 58 inches tall meets the height condition.

The criterion to go on the carnival ride, as provided in the question, is that the person must be at least 55 inches tall.

Therefore, any person who is 55 inches or taller can go on the carnival ride. This is a basic application of inequalities in Mathematics.

For example, if John is 58 inches tall and Maria is 52 inches tall, only John would be able to go on the ride because he meets the height requirement (58 is greater than or equal to 55), whereas Maria does not (52 is less than 55).

Anyone who meets or exceeds the minimum height requirement of 55 inches can go on the carnival ride, as this is the condition set by the operators.

9 as 9 = 3×3 is square not cube

The two numbers are 41 & 37.

The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):

(x) + (x + 4) = 78

Now, we need to simplify it (combine like terms):

2x + 4 = 78

Then you can solve it like any other equation. Subtract 4 on both sides:

2x = 74

Divide by 2 on both sides:

x = 37.

So, now you know one number is equal to 37 and that the other is 37 + 4.

That's how you get 37 & 41.

X = ?

X +4= ?

(X+4) + x = 78

2X + 4 = 78. Subtract 4 from both sides

You get 2X = 74.  Divide both sides by 2 and you get x= 37

Now plug 37 in and you get 37 and 41

Answer: k=x^3

Step-by-step explanation: When I solved this, I got that the blank (which I assigned to variable k to) is equal to x^3 (this means that the answer of the blank depends on the value you give x).

First, add the profit wanted with the costs.

1500 + 200 + 100 = 1800

The total amount wanted is 1800. Each student pays $5, and so you divide by 5

1800/5 = 360

360 students must show up.

The equation used is:

Let student = s

Total cost = 200 + 100

Charge = 5n

Profit = 1500

1500 = 5n - 300 (is equation)

Hope this helps

Answer is A. 5n - 300 = 1,500

2+5y+2y=-12

the answer to your question is

v= -2

x + (-7) = 3

To solve this, add 7 on both sides

Final Answer: x = 10

X+(-7)=3

x-7=3

Add 7 on both sides.

x-7+7=3+7

x=10

Answer:

15

15

Step-by-step explanation:

x + 20 = 35

   - 20   -20

        x = 15

5x - 14 = 16 + 3x

    + 14   +14

5x        = 30 + 3x

-3x                - 3x

2x         = 30

x            = 15

Answer:

The first box plot.

Step-by-step explanation:

In a box plot, the lower quartile is the right hand side of the box.  In the first plot, this is 3.

The upper quartile is the left hand side of the box.  In the first plot, this is 8.

The interquartile range is the difference between these two values:

8-3 = 5.

Removing a proton makes the atom negatively charged, adding a proton would result in a positive ion(called a cation). But addition and removal of protons is not really practical, it is an atomic reaction, Not only does it result in a charge but would change the atomic number and therefore what the element actually is.

I don't know if this will help in anyway but I hope it does!

5.34x10⁵ is c) 10,000,000 times a) greater than 5.34x10⁻⁻², with the comparison made by analyzing the exponents in scientific notation.

The relationship between 5.34x10⁵ and 5.34x10⁻² can be understood by comparing their magnitudes in scientific notation. Scientific notation allows us to easily see how many times larger or smaller one number is compared to another by comparing the exponents of ten.

When comparing 5.34x10⁵ to 5.34x10⁻², we must look at the difference in exponents. The exponent of the first number is 5, while the exponent of the second number is -2. To calculate how many times greater the first number is than the second, we subtract the smaller exponent from the larger one: 5 - (-2) = 5 + 2 = 7. Therefore, the difference in exponents is 7, which means 5.34x10⁵ is 10⁷ times larger than 5.34x10⁻².

The value of 10⁷ is 10,000,000. Thus, we can say that 5.34x10⁵ is 10,000,000 times greater than 5.34x10⁻².

Answer:

12a - 31 = 0

Step-by-step explanation:

3(2a - 6) = -6a + 13

6a - 18 = -6a + 13

6a - 18 + 6a - 13 = 0

12a - 31 = 0

7 rows in total. However, to be more precise, it's 7.75. But you round that down to 7, so 7 exact shelves. All you do is 558 divided by 72, and you get 7.75 which is 7 shelves cause you can't half 7 and .75 shelves
