Answer:

3(3y-1)

Step-by-step explanation:

use distributive property to check you work. #1 for example, when you multiply 3 by y and 3 by 1, you get 3y-3, which is incorrect.

B on the other hand, when you multiply 3 by 1, you get 9y-3

3(3y - 1) because 3x3y = 9y and 3x-1 = -3 so in total it is 9y-3

If on the unit circle C , the distance from P (1, 0) to the point T ( 5/13, 12/13 ) is x , determine the coordinates of the poin
Lorico [155]

Answer:

T' (\frac{5}{13},- \frac{12}{13})

Step-by-step explanation:

See the diagram attached.

This is a unit circle having a radius (r) = 1 unit.

So, the length of the circumference of the circle will be 2πr = 2π units.

Now, the point on the circle at a distance of x along the arc from P is T(\frac{5}{13},\frac{12}{13}).

Therefore, the point on the circle at a distance of 2π - x along the arc from P will be T' (\frac{5}{13},- \frac{12}{13}), where, T' is the image of point T, when reflected over the x-axis. (Answer)

What are the slope and y-intercept -3x-8y=10
choli [55]
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
