Which of the following statements best describes the relationship between the point (5,-20) and the system of
inequalities below?

Answers

Answer: The point (5,-20) only satisfies the second inequality statement in the system of inequalities shown.

Step-by-step explanation:

It isn't super clear exactly what you're asking, but the first thing we can do is see if the point (5, -20) satisfies the system of equations.

So, we start by plugging in -20 for y and 5 for x.

y > -2x-3

-20 > (-2)(5) - 3

-20 > -10-3

-20 > -13. - we can see that the coordinates DO NOT satisfy the first inequality, now we can try the second equation.

y ≤ 3x + 2

-20 ≤ 3(5) + 2

-20 ≤ 15 +2

-20 ≤ 17 - this inequality is true because -20 is indeed less than 17.

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

9x^2-36x+16

A.True
B.False

Answers

Step-by-step explanation:

9x² - 36x + 16

= (Ax - B)² = A²x² - 2ABx + B².

By Comparing Coefficients, we have:

A² = 9,

2AB = 36,

B² = 16.

It is obvious that A = 3 and B = 4.

However 2AB = 2(3)(4) = 24 which is not equal to 36.

Hence 9x² - 36x + 16 is not a perfect square trinomial.

Answer:

False

Step-by-step explanation:

The polynomial cannot be factored.

Answers

Answer:

m + (m + 15) + (m + 2)

Step-by-step explanation:

Even thought we don't know the value of m, we can use expressions to represent it.

Hope this helps.

The required expression is m + (m + 15) + (m + 2) which represents the total number of miles Marla, Lawrence, and Jerry drove in all.

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.

Let's represent Marla drove "m" miles.

Since Lawrence drove 15 more miles than Marla.

So, this means the expression m + 15

Then Jerry drove 2 more miles than Marla.

So, this means the expression m + 2

Now, the total number of miles = m + (m + 15) + (m + 2)

This expression represents the total number of miles Marla, Lawrence, and Jerry drove in all.

Which function represents exponential decay with 5% as the rate of decrease?

Answers

Answer:

The function that represents exponential decay is y = 50 [tex](0.95)^{x}[/tex] ⇒ B

Step-by-step explanation:

The form of the exponential growth function is y = a [tex](1+r)^{x}[/tex]

The form of the exponential decay function is y = a [tex](1-r)^{x}[/tex]

a is the initial valuer is the rate of increase or decrease in decimal

∵ The function represents exponential decay with 5%

→ By using the second rule above

∴ y = a [tex](1-r)^{x}[/tex]

∵ The rate of decrease is 5%

∴ r = 5%

→ Change it to decimal by dividing it by 100

∵ 5% = 5 ÷ 100 = 0.05

∴ r = 0.05

→ Substitute it in the equation

∵ y = a [tex](1-0.05)^{x}[/tex]

∴ y = a [tex](0.95)^{x}[/tex]

→ Look at the answer to find which equation is written in this form

∴ y = 50 [tex](0.95)^{x}[/tex]

∴ The function that represents exponential decay is y = 50 [tex](0.95)^{x}[/tex]

We are told that the two players, taken together, scored a total of 49 points. What is the probability that player A scored first?

Answers

Answer:

1/2 or 50% probability

Step-by-step explanation:

There are just two players, player A and player B. Since it is between this two players, for player A to score first we would have:

AB where player A is the first player to score, we wouldn't have BA since player would not be the first here

Probability = number of favorable outcomes/total number of outcomes

Therefore probability of A being the first player = number of A/total number of players

=1/2 = 0.50

There is therefore a 50% chance of A being the first player

Admission to the local amusement park cost $5.25 and each ride cost $2.50 which of the following equations represents the cost C in dollars for admission to the park with ex ride tickets?

Answers

Answer:

C=2.50r+5.25

Step-by-step explanation:

(r represents each ride cost)

5.25 would be the y-intercept since that's the initial fee to enter the park, and 2.50 would be the slope since each ride would cost that much.

5.25+2.5x=c (cost) x is how many rides

Step-by-step explanation:

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?

Answers

Answer:

Mei descends faster

Mei's height decreases 5ft every second

Victor's height decreases 3.33 ft every second

Step-by-step explanation:

Given

Mel

[tex](x_1,y_1) = (2,50)[/tex]

[tex](x_2,y_2) = (5,35)[/tex]

Victor

[tex](x_1,y_1) = (1,60)[/tex]

[tex](x_2,y_2) = (4,50)[/tex]

Required

Who descend faster?

To do this, we simply calculate the slope/rate of both individuals

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For Mei:

[tex]m_1 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex](x_1,y_1) = (2,50)[/tex]

[tex](x_2,y_2) = (5,35)[/tex]

[tex]m_1 = \frac{35 -50}{5 - 2}[/tex]

[tex]m_1 = \frac{-15}{3}[/tex]

[tex]m_1 = -5[/tex]

Mei descends at 5ft per second

For Victor:

[tex]m_2 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex](x_1,y_1) = (1,60)[/tex]

[tex](x_2,y_2) = (4,50)[/tex]

[tex]m_2 = \frac{50-60}{4 - 1}[/tex]

[tex]m_2 = \frac{-10}{3}[/tex]

[tex]m_2 = -3.33[/tex]

Victor descends at 3.33ft per second

By comparison:

Mei descends faster

Mel: -5, 5

If the point (8,-5) is 6 units above the point P(x, y) and 3 units to the right of it, then what are the coordinates of
the point P(x, y)?

Answers

Answer:

(5, -11)

Step-by-step explanation:

We know that (8, -5) is 6 units above and 3 units to the right of point P. Knowing this, let's work backwards by starting from (8,-5) and counting 6 units down and 3 units to the left on the graph.

If you counted correctly, this should place you at the (5, -11). (You can also check your work by counting 6 units up and 3 units to the right from (5, -11) and seeing if you end up at (8, -5).)

Answers

Answer: y=-1/3x+5

Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!
