Use the rule of <em>SINE(A+B)= SINACOSB+COSASINB</em>
:. SIN(23pi/4+11pi/6)
-add both fractions
:. SIN(138pi/24+44pi/24)
-Simplify
:.SIN(182pi/24)
And simplify again the fraction
:.SIN(91pi/12) ---------Final answer
Answer:
X=10
Step-by-step explanation:
20/2=10
An expression equivalent is 1/3 x 10
3x + 4y = 5
2x - 5y = 8
To answer this question, we need to put both of these equations into Slope-Intercept form, or in other words, solve for y.
3x + 4y = 5 Subtract 3x from both sides
4y = -3x + 5 Divide both sides by 4
y =
+
2x - 5y = 8 Subtract 2x from both sides
-5y = -2x + 8 Divide both sides by -5
y =
-
When you look at the two equations, you can see that their slopes are completely different, so they aren't parallel, or inconsistent. Since

, they aren't the same line, or dependent. So, the only option left is that they are
consistent and independent.</span>
