6 0

Answer:

(0, -4)

Step-by-step explanation:

I don't quite know how to explain it, but I was taught that the number in the equation that doesn't have a variable, in this case -4, is the y-intercept. The order pair is (0, -4) because a y-intercept is where the line crosses the y-axis and the y-axis is located on the 0 of the x-axis.

A binomial distribution
Alina [70]

Answer:

0.324

Step-by-step explanation:

Given that :

Success rate = 30%

p = 30% = 0.3

q = 1 - p = 1 - 0.3 = 0.7

Number of trials, n = 6

Probability of having exactly 2 successes ; x = 2

P(x = 2)

Usibgbtge binomial probability relation :

P(x = x) = nCx * p^x * q^(n-x)

P(x = 2) = 6C2 * 0.3^2 * 0.7^4

P(x = 2) = 15 * 0.3^2 * 0.7^4

P(x = 2). = 0.324135

P(x = 2) = 0.324

3x-4y=-5 y=4x-2 Is (1,2) a solution of the system?
Orlov [11]
If you want to check if (1,2) is a solution to the system, you have to plug the x and y values back into both equations. If they work for one equation, but not the other, than the coordinates are not a solution to the system.

3(1) - 4(2) = -5
3 - 8 = -5
-5 = -5 

2 = 4(1) - 2
2 = 4 - 2 
2 = 2

Since both of these checks are true, then (1,2) is a solution to the system.

A line contains the point ( 3, 4). If the slope of the line is -2/3write the equation of the line using slope-intercept form.
mina [271]
You use point-slope form, which is y-y1=m(x-x1) , so it becomes 
y-4=(-2/3)(x-3). 
You can make it 3y-12=-2x+6.
Add 12 to both sides to make it 3y=-2x+18.
Lastly, divide everything by 3, so it becomes y=-2/3x+6.
