Answer:
fully simplified answer: x^2-2x+8
Step-by-step explanation:
Answer:
(y1-y2)/(x1-x2)
Step-by-step explanation:
if you have two points from the graph then you can use them to find the slope, for example:
(2,3) and (0,5)
you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:
3/2 and 5/0
Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):
3-5/2-0
Then you solve:
-2/2
-1
which means that -1 is the slope for this
(the "/" is a fraction bar, in case you didn't already know that)
Answer:
is this the whole assignment because choose a question
Answer:
72 : 18
Step-by-step explanation:
The ratio of the two complementary angles is 4 : 1
4x + 1x = 90
5x = 90
x =18
4x = 4(18) = 72
x = 18
Therefore the ratio is 72 : 18
Answer: 72 : 18
