The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)
Answer:
-1/2x
Step-by-step explanation:
-1/2x represents the slope because it shows that the line is going down 1/2 every x. 1/4 would be where the line started or the y-intercept.
40-4x=2/3x-10
50=14/3x
150/14=x
75/7=x
Answer:
A
Step-by-step explanation:
Cause 4 times 4divide by 4 is is 1 so 1/4
Answer:
The probability that a student takes Spanish given that the student is taking Computer Programming = 0.375
Step-by-step explanation:
Given -
Let event A = student takes Spanish
Event B = student takes Computer Programming
= student takes Computer Programming and Spanish
P(B) = 0.4 ,
= 0.15
What is the probability that a student takes Spanish given that the student is taking Computer Programming =
(Probability of an event occuring given that another event has already occured , we use condition probability )

= 
= 0.375
