Which ordered pair can be added to the table so that y is still a function of x

A. 4,5

B. 2,5

C. 0,4

D. -2,4

Answer: Look at explanation for the answer please, I am too exhausted to type the answer here

Step-by-step explanation:

y = 10sqrt(5) from the pythagorean theorem

The angle opposing z is arctan(2)

So, find z by the equation

z/y = tan(arctan(2)) = 2

z = 20sqrt(5)

And finally, find x by the pythagorean theorem

x = sqrt(1600) = 40

By inspection, each value of u is obtained by multiplying s by 14.

So the relationship is s=14u.

Answer:

420 miles after lunch

Step-by-step explanation:

Day 1 is 630 miles travelled - total amount of travelling.

After lunch is twice the amount of m.

Twice means 2.

So,

2xm + m (they'd have travelled) = 630 total miles

(2xm = 2m & 1m is the same as m)

2m + 1m = 630

3m = 630

÷3

m = 210 miles

Initial miles travelled before lunch was 210.

After lunch is double that amount.

Thus, 210 x 2 = 420 miles

Check:

210 + 420 = 630 miles.

Hope this helps!

This is a reflection over a horizontal line.

Let's find the line by calculating the difference of the y-coordinates of corresponding points:

The middle line is:

The amount of kobo you can get in the naira is; 100 kobo

There are different types of currencies in the world such as dollars, pounds, euros, naira e.t.c

Now, for the naira, we know that a conversion;

100 kobo = 1 naira

Thus, we can conclude that the amount of kobo you can get in the naira is 100 kobo

100 Kobo is equal to 1 Nigerian Naira (NGN). However, please note that currency exchange rates can fluctuate over time, so it's always a wise idea to check for the most up-to-date information from a reliable source such as a bank or financial institution.

Answer:

Look at the variables and numbers in the equation, and what it equals

Step-by-step explanation:

Expressions that are the exact same have infinite solutions

[tex]5x+3=5x+3[/tex]

Expressions that are different have 1 solution

[tex]6x+7=5x-2[/tex]

Expressions that are the same with different operands have no solution

[tex]5x-3=5x+3[/tex]

Explanation:

The short of it is that when the equations are in the same form, if one equation is the same as or a multiple of the other, there are infinite solutions. If one equation is the same as or a multiple of the other, except for the constant terms, there are no solutions. Otherwise, there is one solution.

Example:

If one equation is x +2y = 3, then you can consider the other equation:

  3x +6y = 9 . . . . 3 times the first equation: infinite solutions

  3x +6y = 6 . . . . 3 times the first equation; constants differ: no solutions

  3x -6y = 9 . . . .  not a multiple of the first equation: one solution

_____

Here's a more formal method.

Put both equations of the linear system of two equations into general form:

  ax +by +c = 0

  dx +ey +g = 0

Perform the following arithmetic:

  p = ae -db . . . . . this is called the system "determinant"

  q = bg -ec

  r = cd -ga

If p = q = r = 0, the equations describe the same line, so there are infinite solutions.

If p = 0 and either of q ≠ 0 or r ≠ 0, the equations describe parallel lines, so there are no solutions.

If p ≠ 0, there is one solution: (x, y) = (q/p, r/p).

_____

Additional comment

This method can always be used to find the solution to a system that is known to have one solution. It often requires fewer arithmetic operations than other solution methods. It is a variation of what is sometimes called the "cross multiplication method."

Answer:

7^2, 10^2, 23^2

Step-by-step explanation:

49 + 100 + 529 = 678

7^2 + 10^2 + 23^2 = 678

Considering the definition of probability, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

Probability is the greater or lesser chance that a given event will occur.

In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.

Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases.

[tex]P(A)=\frac{number of favorable events}{ total number of possible events}[/tex]

The probability of event A can only be a number between 0 and 1; although it can also be written as a percentage.

In this case, you know:

Replacing in the definition of probability:

[tex]P(A)=\frac{12}{ 139}[/tex]

Finally, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

Answer:

1.5

Step-by-step explanation:

Amplitude: the height from the center line to the maximum or minimum point.

We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.

From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5

Therefore, the distance between them = -0.5 - -3.5 = 3

Divide by 2 = 3/2 = 1.5

Therefore, the amplitude = 1.5

Answer:

  B.  b(a) = a/6 -9

Step-by-step explanation:

Solve the given equation for b.

Answer:

John = $44   Mary = $49.50

Step-by-step explanation:

2/3 + 3/4 = 17/12

17/12x = 93.5

17/12x x 12 = 93.5 x 12

17x = 1122

17x/17 = 1122/17

x = 66

2/3x = 66 x 2/3

2/3x = 44

3/4x = 66 x 3/4

3/4x = 49.5

44 + 49.5 = 93.5

John earned $44 while Mary earned $49.5.

Answer:

20,000

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

Answer:

the company's total budget is 20,000

Step-by-step explanation:

A company spends 13% of its month budget on rent which total $2600

Let x be the month budget on rent

13% of the month budget is 2600

13% can be written as 13/100

Now we solve for x

multiply both sides by 100

divide both sides by 13

x=20000

So, the company's total budget is 20,000
