Answer: c. -4 degrees Celsius
Step-by-step explanation:
If it rises by 17°C, then add it to the -21°C in the thermometer:
-21 + 17 = -4°C
Hope this helps!
Answer:
8 units
Step-by-step explanation:
find the distance of the lines through coordinates given
distance formula: 
i) CD=
CD=
CD=4 units
ii) DE=

DE=
DE= 2 units
iii) ED=
ED=
ED=
ED= 2 units
perimeter of polygon= 2 units+ 2 units+ 4 units
=8 units
Answer:
The answer is 1/4
Step-by-step explanation:
When you split something into fourths, you each get 1/4 of it.
Answer: Y=-1/4x
Step-by-step explanation:
A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).
The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).
Putting these two values together we get:
m (slope) = rise / run
m = -1 / 4
Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:
y = (-1/4)x
