Answer:
slope-intercept form equation: y = x + 5
Step-by-step explanation:
you take the 2 y's, 18 and -13, then you subtract them: 18 - (-13) = 31
then you take the 2 x's, 13 and -18, subtract them too: 13 - (-18) = 31
divide those 2 sums: 31/31 = 1
so the slope is 1
then when you graph it you get an y-intercept of 5
so the equation is y = x + 5
hope this helps :)
Hi there!
Answer:
The temperature at lunchtime is 0 degrees Celsius.
Step-by-step explanation:
This is because we started at -2 and when we add 2 that brings us back at 0 (or neutral).

A kilometer is 1000 meters.
1000 time 750 equals 750000
So the answer is yes, 7500000 is greater than 750000
A ) cos² x · 1 / sin x - 1 / sin x = - sin x
cos² x - 1 / sin x = - sin x
- sin² x / sin x = - sin x
- sin x = - sin x ( correct )
B ) sin x ( cos x / sin x + sin x / cos x ) = 1 / cos x
sin x · ( cos² x + sin²x ) / sin x cos x = 1 / cos x
sin x · 1 / sin x cos x = 1 / cos x
1 / cos x = 1 / cos x ( correct )
C ) cos² x - sin² x = 1 - 2 sin² x
1 - sin² x - sin² x = 1 - 2 sin² x
1 - 2 sin² x = 1 - 2 sin² x ( correct )
D ) 1/sin²x + 1/ cos²x = 1
cos²x + sin² x / sin² x cos² x = 1
1 / cos² x sin² x = 1
cos²x sin² x ≠ 1
Answer: D ) is not an identity.
