Okay well first let's find out the answer for the equation as given here;

4p^2 = 12p - 5

4p^2 - 12p + 5 = 0

4p^2 - 2p - 10p + 5 = 0

2p(2p - 1) - 5(2p - 1) = 0

(2p - 5)(2p - 1) = 0

p = 5/2, 1/2

now the question is asking what type of numbers are the solutions.

your answer is D) 2 rational solutions.

hope this helped (:

Pls help! URGENT ONLY DO QUESTION 21 PLS
Alekssandra [29.7K]

Answer:

y = x - 8

Step-by-step explanation:

There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!

Looking at inputs 20 and 21, the outputs are 8 less than the inputs.  Check the other inputs and notice that the same pattern holds up.

Why do scientist collect data
julsineya [31]

As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research.

2) Line segment MK has endpoints at (2, 3) and (5, ?4). Segment M'K' is the reflection of MK over the y-axis. Which statement de
Marianna [84]

Answer:

Option C -M'K' is the same length as MK

Step-by-step explanation:

Given : Line segment MK has endpoints at (2, 3) and (5,4)

               M'K' is the reflection of MK over the y-axis

By definition of reflection: reflection of point (x,y) across the the y-axis is the point (-x,y)

which implies M'K' has end points (-2,3) and (-5,4)

Now, we find the length of MK

let (x_1,y_1)=(2,3)\\\\(x_2,y_2)=(5,4)

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒ d=\sqrt{(2-5)^2+(4-3)^2}

⇒d=\sqrt{9+1}

⇒d=\sqrt{10}   ....(1)

Now, we find the length of M'K'

let (x_1^{'},y_1^{'})=(-2,3)\\\\(x_2^{'},y_2^{'})=(-5,4)

d^{'}=\sqrt{(x_2^{'}-x_1^{'})^2+(y_2^{'}-y_1^{'})^2}

⇒ d^{'}=\sqrt{(-2+5)^2+(3-4)^2}

⇒d^{'}=\sqrt{9+1}

⇒d^{'}=\sqrt{10} .....(2)

from (1) and (2) we simply show that the length of MK and M'K' is equal

we can also refer the figure attached for reflection of MK and M'K'

therefore, Option C is correct

What is the answer to 6= a/4 + 2
Zina [86]
Solve for a.

6 = a / 4 + 2

Subtract 2 from both sides.

4 = a / 4

Multiply both sides by 4.

16 = a
