Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3
Answer:
2
Step-by-step explanation:
You solve this through error and trial.
The is to get two matching numbers at both sides.
<u>X 2x + 3 = 3 (x + 1) - x </u><u> </u><u> </u><u> </u><u>Answer</u>
0 2(0) + 3 = 3 (0 + 1) - 0 3 = 3
1 2(1) + 3 = 3 (1 + 1) - 1 5 = 5
You do this all the way to ten. So far, we know x = 0 and x = 1 is correct
Answer:
![-\frac{x-4}{9}](https://tex.z-dn.net/?f=-%5Cfrac%7Bx-4%7D%7B9%7D)
Step-by-step explanation:
Replace x with f(x)
solve for f(x)
Answer:
(D)56.4
Step-by-step explanation:
According to the question, Let AB=10, AC=12 and m∠B=90°.
Thus, from ΔABC, using trigonometry, we have
![\frac{AB}{AC}=sinx](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAC%7D%3Dsinx)
![\frac{10}{12}=sinx](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B12%7D%3Dsinx)
![\frac{5}{6}=sinx](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%3Dsinx)
![sinx=0.83](https://tex.z-dn.net/?f=sinx%3D0.83)
![x=sin^{-1}(0.83)](https://tex.z-dn.net/?f=x%3Dsin%5E%7B-1%7D%280.83%29)
![x=56.4](https://tex.z-dn.net/?f=x%3D56.4)
Therefore, at
the wire meet the ground.
