(d): y=2-4x
P(0;y) belongs to (d)
=> y=2-4*0
= 2
So P(0;2)
Q(x;0) belongs to (d)
=> 0=2-4*x
<=> x=1/2
So Q(1/2;0)
The answer is D. Because, for every 50 emails dent he received 30 back in response. So, let 5 represent the emails he sent and let 3 represent the emails received... so your answer should be D: 5:3.
I hope this helps!!! Have a good day!!! :D
Answer:
Price of advance ticket: 15$
Price of same-day ticket: $40
Step-by-step explanation:
Let
be the price of one advance ticket and
the cost of one same day ticket.
We know that the combined cost of one advance ticket and one same-day ticket is $55, so
equation (1)
We also know that 20 advance tickets and 35 same-day tickets cost $1700, so
equation (2)
Now, let's solve our system of equations step-by-step:
step 1. Solve for
in equation (1)

equation (3)
step 2. Replace equation (3) in equation (2)





equation (4)
step 3. Replace equation (4) in equation (3)



We can conclude that the price of one advance ticket is $15 and the price of one same-day ticket is $40.
Solution
Step 1
Two distinct lines intersecting each other at 90° or at right angles are perpendicular to each other.
Hence apply this to question 8 the type of lines shown in the figure is perpendicular lines. Option C
Step 2
To explain this as stated above line A and line B intersect each other at a right angle hence line A and B are perpendicular lines. The line segments are seen below.
