Answer:
you dont, just make a vertical line where you plotted your point
Step-by-step explanation:
I am going to explain this as best as i can because i dont really remember how to do this
My teacher taught it to me as:
y is fly
so when you get an equation like this but with a y you will plot the dot on the y axis and make a horizontal line
x is dive
when you get an equation like this one you will plot the dot (exactly how you did it) and make a vertical line on that dot
i dont really know how to explain so sorry if you dont understand, hope it helps
Answer:
Therefore A = (0.4338) = 64.29°
Step-by-step explanation:
i) Law of cosines: = + – 2bccos(A)
ii) XZ = a = 16 , YZ = b = 12, XY = 17, ∠Y = ∠A
iii) = + - (2 12 17 cos(A))
⇒ 256 = 144 + 289 - 408cos(A)
⇒ 256 - 144 - 289 = -408cos(A)
⇒ -177 = -408cos(A)
⇒ cos A = = 0.4338
Therefore A = (0.4338) = 64.29°
Answer:
7/8
Step-by-step explanation:
Because he has three brothers, and it also depends on how many times the spinner turns on each turn
The correct answer is 16.8
Answer: One POSSIBLE answer is (0,9)
Step-by-step explanation: This may look hard but it's actually super easy. All you have to do is substitute a value for x and see what you get as the y value. The first thing I would do is rearrange the equation so that the equation is in the format y = something. So the first thing you should do is subtract 6x from both sides of the equation and you should get -y=-6x+9. Right now, the y is being multiplied by -1, and to undo multiplication, you have to divide. So divide both sides of the equation by -1 (remember, what you do on one side of the equation, YOU HAVE TO DO THE SAME THING ON THE OTHER SIDE). So your new equation would be y=6x-9. Then, all you have to do is substitute a value for x and see what you get for y (x is basically the input and whatever you get for y is the output). S for example, let's say that x=0. So substitute a 0 in the equation wherever you see an x. So in this case, you would get y=(6x0)+9. Then you just simplify. So 6x0 is 0 and 0+9=9 So y=9
TO RECAP: Rearrange the equation so that the equation is in the format y = something. Then, input any number for x, and whatever you get for y is what you put in the brackets as your y value for your final answer.
Hope this helps!
