Which statement about the ordered pairs (−9, 3) and (2, −4) is true for the equation 6x−y2=14 ?

(2, −4) is a solution to the equation.
Both ordered pairs are solutions.
Neither ordered pair is a solution.
(−9, 3) is a solution to the equation.

Answers

Answer 1
Neither ordered pair is a solution.
If you solve y^2-6y + 14 = 0 you'll see by the discriminate b^2-4ac
that it is not a perfect square, i.e = -20, so the solutions are imaginary numbers, i.e. no real solutions.

True ir false: multiplying 7x43, a reasonable estimate of the product is 280? Why?

Answers

No because 280 is 21 numbers away from 301
Final answer:

Multiplying 7 by 43 gives an exact result of 301. Thus, estimating this product as 280 isn't entirely accurate but might be seen as a reasonable approximation in certain contexts.

Explanation:

The statement 'multiplying 7 by 43, a reasonable estimate of the product is 280' is known as the question. For this multiplication equation, 7 x 43, the accurate result is 301. Therefore, estimating the product as 280 is not fully correct, however it is relatively close and might be considered a reasonable approximation depending on the context. For a stronger approximation, the product could be rounded up to 300.

Which expression is equivalent to-8+7.25-6+0.5

Answers

Final answer:

The expression equivalent to -8+7.25-6+0.5 is calculated by first adding the positive numbers to get 7.75, then adding the negative numbers to get -14, and finally combining these to get an equivalent expression of -6.25.

Explanation:

To find an expression equivalent to -8+7.25-6+0.5, you need to perform addition and subtraction operations in the order they appear because they have the same level of precedence. Adding positive and negative numbers together is simplified by combining like terms, often starting with the positive numbers for easier calculation.

First, add the positive numbers together: 7.25 + 0.5 equals 7.75. Next, add the negative numbers: -8 + (-6) equals -14. Finally, combine the sum of the positive numbers with the sum of the negative numbers: 7.75 + (-14) equals -6.25.

The equivalent expression is hence -6.25.

It's just not realistic to present a list of 12 math questions and ask for the answers to all of them at once.  Please post only one question at a time and please share your thoughts about how to solve that question.

I'll focus on one problem:    7 2/3 + 2 7/12

Here the LCD (lowest common denominator) is 12.  7 2/3 becomes 7 8/12.

Add 7 8/12 and 2 7/12:


 7 8/12
+2 7/12
-----------
9 15/12                15/12 is not a proper fraction.  Write it as 1 3/12, or 1 1/4.

Then your 9 15/12 becomes (9+1)  1/4, or 10 1/4.

The expressions given above are solved.

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Answers

Answer:

1.6 hours or 1 hour 36 minutes

Step-by-step explanation:

We have been given an equation [tex]t=\frac{1}{500}d[/tex], where d represents distance traveled in miles and t represents time in hours.

To find the time taken by the flight to travel 800 miles, we will substitute [tex]d=800[/tex] in our given equation as:

[tex]t=\frac{1}{500}\times 800[/tex]

[tex]t=\frac{800}{500}[/tex]

[tex]t=\frac{8}{5}[/tex]

[tex]t=1.6[/tex]

1 hour equals 60 minutes.

0.6 hours = 0.6*60 minutes = 36 minutes.

Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

Using the equation, it is found that it will take 1.6 hours for the airplane to travel 800 miles.

The equation that relates the time in hours needed to travel d miles is given by:

[tex]t = \frac{1}{500}d[/tex]

In this problem, we want the time needed to travel 800 miles, thus [tex]d = 800[/tex], and:

[tex]t = \frac{1}{500}(800) = \frac{800}{500} = 1.6[/tex]

It will take 1.6 hours for the airplane to travel 800 miles.

 /15= /15

x=9

It will take 9 months 
Final answer:

Jones Middle School will have more students than Roberts Middle School after 9 months.

Explanation:

To find out after how many months Jones Middle School will have more students than Roberts Middle School, we need to determine the point at which the number of students at Jones Middle School exceeds the number of students at Roberts Middle School. Let's calculate the number of months it takes for this to happen:

Number of students at Jones Middle School = 850 + 5n (n represents the number of months)

Number of students at Roberts Middle School = 985 - 10n (n represents the number of months)

We need to find the value of n when the number of students at Jones Middle School is greater than the number of students at Roberts Middle School:

850 + 5n > 985 - 10n

Simplifying the inequality:

15n > 135

n > 9

Therefore, after 9 months, Jones Middle School will have more students than Roberts Middle School.

PLEASE HELP GEOMETRY Use the word bank to help you with possible answers (there are extra options that are not to be used)

Word Bank:

SAS
BC=EF
BC=ED
Given
CPCTC
BC = EF

Answers

Short Answers:

Answer for part A: Given
Answer for part B: Angle A = Angle D (not sure why this isn't in word bank?)
Answer for part C: ASA
Answer for part D: BC = EF
Answer for part E: CPCTC

-------------------------------------------------------------

Explanations:

Part A:

AB = DE is given at the very top of the problem. So we simply say "given". We always repeat what we are given at the very start of the proof. You can see this for lines 1 through 3, which are repeating the three givens. 

---------------------

Part B:

The three givens are:
AB = DE
angle A = angle D
angle B = angle E
the first and last of this trio is used (for statements 1 and 3 respectively). So the only thing left is "angle A = angle D"

---------------------

Part C:

We're using ASA (angle side angle) because we're given two pairs of congruent angles. The side for each triangle is between the two angles. See the attached diagram for more info.

---------------------

Part D:

For any proof, you will ALWAYS have the last statement be the thing you want to prove. In this case, we want to prove BC = EF. 

---------------------

Part E:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

If the two whole triangles are congruent, then the smaller corresponding parts that make up the triangles must be congruent as well.
