K×4-7=k/2/3
4k-7=k×3/2
4k-7=1.5k
4k-7-4k=1.5k-4k
-7=-2.5k
-7/-2.5=-2.5k/-2.5
2.8=k
Answer:
(66.50) is the answer. Choose that one.
Answer:$18.20
Step-by-step explanation: deposit means to put in, so you would subtract -$3.20 by $15 to get $18.20, which is his new balance.
We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.
distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A
_____
There is no question 17.
_____
15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.
Answer:
Step-by-step explanation:
Sec²A-cosec²A=(tanA+cotA)(tanA-cotA)
Tan^2A+1-cot^2A-1=(tan^2A-cot^2A)
tan^2A-cot^2A=tan^2A-cot^2A
L.H.S=R.H.S
Hence proved.
