Answer:

The points (2,0), (4,0), and (0,0) are on the line which is parallel to the x-axis.

Step-by-step explanation:

If a line is parallel to the x-axis then, the x-coordinate changes but the y-coordinate remain constant.

Now, in the points (2,0), (4,0), and (0,0) the y-coordinate remains the same but is equal to 0.

Since x-axis itself is a parallel to the x-axis with distance fro the x-axis equal to zero.

Therefore, the points (2,0), (4,0), and (0,0) are on the line which is parallel to the x-axis. (Answer)

Having to do with the $1200 per month & $35 for every phone you sell

docker41 [41]

Since her base amount is 1200, we have 1200+<number>=<number>. Since she gets 35 dollars for every phone, if the number of phones she sells is x, we have 1200+35*x=the total amount of money in a month =4000 . Subtracting 1200 from both sides, we get 2800=35*x and by dividing both sides by 35 we get x=80

An experiment is broken up into two parts. In the first part of the experiment a penny is tossed in the air. If the coin lands o

-BARSIC- [3]

There are two chances of getting one tails: if the first toss is heads and the second toss is tails OR if the first toss is tails.
The probability of the first toss to be head AND the second toss to be tails is 1/2 × 1/2, which equals 1/4.
The probability of getting a tails on the first toss is 1/2.

When dealing with probabilities, AND means multiply and OR means add. Therefore, this problem is: (heads AND tails) OR (tails). The probability of a coin landing on heads is 1/2 and the probability of a coin landing on tails is 1/2. Therefore, the equation is (1/2 × 1/2) + (1/2), which is 3/4.
