Answer 1

Answer: (6,2)

Step-by-step explanation:

Replace all occurrences of

y with 2x−10 in each equation.

−x+20=14

y=2x−10

Solve for x in the first equation.

x=6y=2x−10

Replace all occurrences of x with 6 in each equation.

y=2x=6

(6,2)

Point Form:

(6,2)

Equation Form:

x=6,y=2

Which statement describes the relationships between x and y in these two equations?

y = 3x

y = x + 3




In y = 3x, the value of y is 3 times the value of x, and in y = x + 3, the value of y is 3 more than the value of x.

In y = 3x, the value of y is 3 more than the value of x, and in y = x + 3, the value of y is 3 times the value of x.

In y = 3x and y = x + 3, the value of y is 3 more than the value of x.

In y = 3x and y = x + 3, the value of y is 3 times more than the value of x.

Answer: 21

Step-by-step explanation: We can use the method: Keep, Change, Flip.

1. Keep 7.

If you want 7 to become a fraction, you can do it like this: [tex]\frac{7}{1}[/tex]

2. Change division to multiplication.

It's very simple. Just change the sign.

3. Flip [tex]\frac{1}{3}[/tex].

It's like converting it into a improper fraction. [tex]\frac{1}{3}[/tex] is now [tex]\frac{3}{1}[/tex].

Now we can solve!

[tex]\frac{7\times3}{1\times1} =21/1[/tex]

Therefore, your answer is 21/1 or just 21.

There no answer because there is a variable next to a number that is being added and you can’t split them

Because there is no sum we can’t find the variable (what R equals) so the answer can only be two things if you are factoring the equation the answer would be 2(R+4). If you are trying to simplify it would remain R2+8.

At a cookout, Mrs. Crawford makes 8/9 pound of chicken, plus 1 pound for each guest. Is the relationship between the number of guests and pounds of chicken proportional? Explain.

Answers

Answer:

No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").

A proportional rel. features mult. only.

Step-by-step explanation:

et x represents the number of guest and y represents the number of pounds of chicken made,

Given,

The number of pounds of chicken for each guest = 1,

So, the number of pounds for x guests = x,

Also, the number of pounds already made =

Thus, the total pounds of chicken,

Since, a relation is called proportional if the variables are directly proportional,

That is, the line obtained by the relation passes through the origin,

Since, if x = 0, y = 0,

∴ Line  does not pass through the origin.

No, it is not a proportional relation. Thus, the total pounds of chicken, ... Hence, given relation is not proportional.

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.

Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Answers

A simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years is given as follows:

Choose three numbers with replacement from the set of 0 to 9, which:

numbers from 0 to 3 representing that Phil is correct.numbers from 4 to 9 represents that Phil is incorrect.

How to calculate a probability?

The parameters that are needed to calculate a probability are given as follows:

Number of desired outcomes in the context of a problem/experiment.Number of total outcomes in the context of a problem/experiment.

Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The probability of a success on a single trial is given as follows:

40% = 0.4, as Phil is correct 40% of the time.

Hence the simulation needs to have three trials, each with a 0.4 = 40% probability of a success.

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?

The measure of the larger angle is
°. what is the angle

Answers

First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x.
