Answer is B. Just plug them in and it works! :)
I remember doing this question. The question went like:
<span>1.25x + 1.49 = 100
What error did Barbara make in writing the equation?
And the answer would be that Barbaras equation did not consider the number of ice tea drinks. Hence, </span>She put the correct price in the equation but she didn't put the (x) number of iced tea drinks. In other words,This is because she has added 1.25 X the number of water bottles sold to 1.49, the cost of one iced tea.
So, the correct equation would be:
1.25x +1.49y = 100
Would really appreciate if you would put me as Brainliest answer.
Answer: Choice A) 45 + k*90
===================================
Work Shown:
2*tan(x) = 2*cot(x)
2*tan(x) = 2*(1/tan(x))
2*y = 2*(1/y) .... let y = tan(x)
2y = 2/y
2y^2 = 2
2y^2 - 2 = 0
2(y^2 - 1) = 0
y^2 - 1 = 0
(y+1)(y-1) = 0
y+1 = 0 or y-1 = 0
y = -1 or y = 1
tan(x) = -1 or tan(x) = 1
-------------
If tan(x) = -1 then x = 135 or x = 315
If tan(x) = 1, then x = 45 or x = 225
This is for 
In more general terms,
x = 45 + k*90
where k is an integer.
Answer:
Step-by-step explanation:
Answer:
(25, 20 ) represents that the dimension of the coral is 25 feet long and 20 feet wide.
Step-by-step explanation:
The general representation P(x,y) represents the Cartesian Representation of a point in a 2 Dimension.
Here, x represents the distance of the point P from y axis to the x axis.
and y represents the distance of the point P from x axis to the y axis.
(x, y) together gives the 2 dimensional representation of the point P.
Now here, the given coordinates are (25, 20)
So, here x = 25 and y = 20
So, (25, 20 ) represents that the dimension of the coral is 25 feet long and 20 feet wide.
Hence, option 3 is the most appropriate.
