Lines a and b in the figure above are parallel. What is the value of p?
elena-s [515]
It will be c- 20:
4q and 2(q+30) have to equal the same therefore q=30 which makes both these equations equal.
3p + 4q then have to equal 180 as they are on a straight line so you know q=30 so 4x30=120 so 180-120=60
Then 60/3=20 and that is your answer.
Hope this helps :)

Evaluate the following<br><br> (1.6 x 10 12) ÷ (8.01 x 10 23)
devlian [24]
To evaluate the given expression, we must follow the rules of PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) in solving.

Therefore, first calculate what's inside the parentheses:

(1619.2) / (8194.23)

 Then perform the operation in between the parentheses:

<span>(1619.2) / (8194.23) = 0.20
</span>
Therefore the answer after evaluating the expression is 0.20.


I hope my answer has come to your help. Thank you for posting your question here in Brainly.

The graph of y = f(x) has a maximum point at (-2, 4).
solmaris [256]

Answer:

(2,4).

Step-by-step explanation:

Graph of y = f(-x).

The values of x in f(-x) assume the values of -x in f(x).

For example, f(-2) in f(x) is f(2) in f(-x), and f(2) in f(x) is f(-2) in f(-x).

b) Write down the coordinates of the maximum point of the graph of y = f(-x).

In f(x), we have that x = -2. So in f(-x), it will be x = 2. y remains unchanged. So

(2,4).
