Answer:
c
Step-by-step explanation:
because it makes the most sense
12x + 24y < = 240
** because 2 hrs and 120 minutes = 240 minutes
Put the negative exponent as the denominator in a fraction, so you'd get -7/1
Answer:
-2 + 7x - 3x is your answer
Step-by-step explanation:
In order to prove the triangle is a right angled triangle we need to prove that the slope of the lines CA and BC and AB have any negative reciprocals.Lets find the slopes .
AB=(-1,3), (1,2) slope of AB = 2-3/1-(-1)= -1/2 slope of AB is -1/2
BC = (1,2), (-3,1) slope of BC is 1-2/-3-1= -1/-4 slope of BC is 1/4
Slope of CA =(-3,1)(-1,3) slope of 3-1/-1-(-3)=-2/-2=1
Since the slopes do not have any negative reciprocals so the triangle is not a right angled triangle
