Which equation shows y = 3/4x - 5/2 in standard form?

Mathematics

ElenaW [278]4 years ago

The format for a standard form is ax+by=c.
So, we need to get rid of fractions in the equation first.
To do this, multiply both sides by the "LCM" of the fraction denominators..
The LCM of 4 and 2 is 4. So, multiply both sides by 4:
4y = 3x - 10
Now, change it to standard form by subtracting 3x from both sides:
-3x + 4y = -10
This doesn't match any of the choices. Am I wrong or is the choices wrong? idk

Point C is located at (1, 2), and point D is located at (−4, −2). Find the x value for the point that is 1 over 4 the distance f
lutik1710 [3]

Answer:

Point C occurs on the line x = 1

Point D occurs on the line y = -2

The intersection of both lines occurs at the point E = (1,-2)

The difference between the x coordinates of points D and E is 1 + 1/4 units

The difference between the y coordinates of points C and E is 1 unit

Let point F be the point that is 1/4 the distance from point C to point D

To find the x-coordinate F subtract the difference between the x coordinate of points C and E from the x-coordinate of C:

1 - (1 + 1/4) = -1/4

To find the y-coordinate of F subtract the difference between the y-coordinates of D and E from the y-coordinate of C

2 - 1 = 1

The coordinates of point F are (-1/4, 1)

Therefore, the y value of the point that is 1/4th the

A credit card contains 16 digits between 0 and 9. However, only 100 million numbers are valid. If a number is entered randomly,
marusya05 [52]

Answer:

P(valid) = 1 * 10^{-8}

Step-by-step explanation:

Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.

We want to form a 16 digit number out of 10 digits, so, we have:

N = 10^{16}

There are 10^{16} numbers that can be formed.

There are only 100 million valid numbers (100 * 10^6 = 10^8). Let the number of valid numbers be n.

Therefore, the probability of picking a number that is valid is:

P(valid) = n / N

P(valid) = 10^{8} / 10^{16}\\\\P(valid) = 1 * 10^{-8}
