Answer:

x = $25.8^{o}$ and y = $51.4^{o}$

Step-by-step explanation:

Known that he sum of angles on a straight line is $180^{o}$ . From the diagram;

2y + x + y = $180^{o}$

x + 3y = $180^{o}$ ................ 1

Also,

2x + x + 2y = $180^{o}$

3x + 2y = $180^{o}$ .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = $180^{o}$ ............. 4

7y = 360

y = $\frac{360}{7}$

y = $51.4^{o}$

substitute the value of y in equation 1,

x + 3y = $180^{o}$

x + 3(51.4) = $180^{o}$

x + 154.2 = $180^{o}$

x = $180^{o}$ - 154.2

x = $25.8^{o}$

Thus, x = $25.8^{o}$ and y = $51.4^{o}$

If f(x)=|3x-4|+2 find f(-10)

Nat2105 [25]

Answer:

$f(-10)=36$

Step-by-step explanation:

$f(x)=|3x-4|+2\\f(-10)=|3(-10)-4|+2\\f(-10)=|-30-4|+2\\f(-10)=|-34|+2\\f(-10)=34+2\\f(-10)=36$

How do you condense 2ln6 - ln3?

Ugo [173]

Ln(6)=ln(3^2)=2*ln(3)
so 2*ln(6) = 4*ln(3)

so 2*ln(6) - ln(3) = 3*ln(3)
