Answer:
y = -2 when x = 0
Step-by-step explanation:
We are given points on the line such as ( 2, 2) and (6, 10) so we can find the equation of the line then find point (x=0, y=?).
General equation of the line is y = mx +b, where m is the slope and
b is y-intercept (where the line crosses the y-axis)
The slope m = (y2-y1)/ (x2-x1) = (10-2)/(6-2) = 8/4 = 2
Now the equation is y = 2x +b
To find b we substitute any of the points that are on the line, for example
(x=2, y=2) in the equation 2=2*2+b; 2-4 =b; -2 = b
The equation is y=2x -2
If x= 0 then y=2*0 -2; y = -2
If N is a positive integer, it must be either even or odd.
If N is odd, then N-1 will be even.
If N is even, then N-1 will be odd.
Either way, when you multiply n and n-1, one of those expressions is going to be an even number, and any number multiplied by an even number is an even number.
Hope this helps! :)
She receives 21. 1/5 of 30 is 6, or the number of picture messages Lilly receives. 7/8 of 24, the number of remaining messages, is equal to 21.
Answer:
