Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
<span>The answer is:
T : (x, y) (x + 4, y + 3)
</span>T⁻¹<span>: (x, y) (x - 4, y - 3)
</span><span>The basic principle is to find the inverse function of F, such that T*</span>T⁻¹ = T⁻¹ * T = I.
Answer:
Option B
Step-by-step explanation:
We are given the following system of equations -

Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -
,

Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -

Now solve through Cramer's Rule -
x = Dx / D = - 6,
y = Dy / D = - 1,
z = Dz / D = 1
<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>
Answer:
x=5.35
Step-by-step explanation:
2x - 1.7 = 9
2x - 1.7 + 1.7 = 9 + 1.7
2x = 10.7
2x/2 = 10.7/2
x=5.35
Hope this Helps :)
