What is the slope of the line through (-10,1)(−10,1)left parenthesis, minus, 10, comma, 1, right parenthesis and (0,-4)(0,−4)
1 answer:
Answer:
Step-by-step explanation:
We have to find the slope of the line through the points (-10,1) and (0,-4).
We know the formula of slope of a straight line when two different points on the line are known to be () and (
) is given by
.
Therefore, in our case () ≡ (-10,1) and (
) ≡ (0,-4)
Therefore, the slope is (Answer)

Answer :
Explanation:
Since we have given that
n(U) = 120, where U denotes universal set ,
n(F) = 45, where F denotes who speak French,
n(S) = 42 , where S denotes who speak Spanish,
n(F∪S)' = 50
n(F∪S) = n(U)-n(F∪S) = 120-50 = 70
Now, we know the formula, i.e.
n(F∪s) = n(F)+n(S)-n(F∩S)
⇒ 70 = 45+42-n(F∩S)
⇒ 70 = 87- n(F∩S)
⇒ 70-87 = -n(F∩S)
⇒ -17 = -n( F∩S)
⇒ 17 = n(F∩S)
