X - y < 0....so sub in ur answer choices to see which one makes the inequality true
subbing in (-2,0)
-2 - 0 < 0
-2 < 0 (true)
so ur answer is (-2,0)
Mass = density x volume
Mass = 3.5 x 20 = 70 grams
Answer:
Cannot be determined
Step-by-step explanation:
The scores are not independent
The midpoint formula is

Therefore,


Answer: (7,2)
You could also plot the points and fold the paper so the points are on top of each other. Make a crease in the paper and when you open it the point where the crease intersects the segment is the midpoint.
Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5
