HELP PLZZZZZ ASAP ASAP I NEED HELPP!!!!!!!which set of ordered pairs represents a function?

A {(-2,5), (6,9), (8,-4), (8,7)}
B{(-1,4),(-5,-2), (6,1),(-2,-2)}
C {(-5, -6),(-5,3), (-7, -8),(-1, -9)}
D{(-8,-4),(-8,-5),(-6, -1), (3,6)}​

Answers

Answer 1
Answer:

Answer:

Only set B

Step-by-step explanation:

Look for pairs (x, y) in the set, where the x value is NOT repeated connecting it with a different y value. The only one like that is set B.

All other sets have repeated x values in their pairs: (8, -4), (8, 7)

(-5,-6) (-5, 3)

and (-8,-4) (-8,-5)

Substitution and elimination are two symbolic techniques used to solve linear equations. For example, if it is easy to set up an equation for substitution where 1 variable is on 1 side, then use that; For example, 4y=16+4x, you can easily divide by 4, get y=4+x (or y=x+4), and plug that into the other equation. In other cases where it may not be so easyFractions/decimals, etc., then you would probably rather use elimination.

1) The substitution method. This method is best utilized when one of the variables in one of the equations has a coefficient of 1 or -1, otherwise you will introduce fractions. Substitution can also be used for nonlinear systems of equations.
(2) Linear combinations also called the elimination method, multiplication and addition method, etc... My personal favorite as it can be done efficiently. It generalizes well to larger systems and is the underpinning of various other solution methods.
As the name implies it requires the equations to be linear.
You need to know both and be comfortable switching between them.

Can we get one for the elimination method too?
Also, can you solve the same problem using either of the two techniques?

Answers

A simple sample problem for Elimination:

x  -  y  = 1
x +  y  =  5

You can solve the same problem using either technique, as far the equations are linear equations.

Answers

Answer: 120d + 1,500 = 110d + 2,500

Step-by-step explanation:

Answer:

$1,500 + 120d = $2,500 + 110d

Step-by-step explanation:

Just in case you want the solution as well:

10d = 1000

d = 100

Rachael and Theodore plant a sunflower.Rachael predicts that it will grow 2/5 foot
per week, while Theodore predicts that it
will grow 3/4 foot per week. The sunflower
grows 4 1/2 feet in 7 1/2 weeks. Which
statement is correct?

Answers

Final answer:

The sunflower grew at a rate of 0.6 feet per week, which is closer to Rachael's prediction of 0.4 feet per week. Therefore, Rachael's prediction was more accurate.

Explanation:

To solve this problem, we have to find the rate at which the sunflower grows in a week. The rate was given as 4 1/2 feet in 7 1/2 weeks. When we divide 4.5 feet (the total growth) by 7.5 weeks (the total time), we get a weekly growth rate of 0.6 feet.

Comparing this with the predictions made by Rachael and Theodore, we can see that the sunflower grew at a rate closer to Rachael's prediction of 2/5 feet per week, which is equivalent to 0.4 feet per week. Therefore, the statement-making Rachael's prediction correct is the accurate one.

Guys I need help I’m gonna fail math

Answers

Answer:

125% correct

3/5 correct

2/3 correct

Step-by-step explanation:

Here, we want to pick the appropriate conversion from percentage to fraction:

To convert from percentage to fraction, we simply divide by 100

125% = 125/100 = 1.25 correct

30% = 30/100 = 0.3 not 0.03 wrong

1% = 1/100 = 0.01 not 0.001 wrong

60% = 60/100 = 3/5 correct

50% = 50/100 = 1/2 not 1/4 wrong

2/3 = 2/3 * 100 = 200/3 = 66.66667% correct
