Answer:
17 1/2
Step-by-step explanation:
1/2 +7 1/2 + 9 1/2
8 + 9 1/2
= 17 1/2
<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5

there is the answer

Step-by-step explanation:
<u><em>uirhgurhehgu5rhginiurogherughre hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii</em></u>
Working:
7y + 42 = -14x
7y = -14x - 42
y = ((-14x - 42) ÷ 7)
Expand and Simplify:
y = -2x - 6
Factorise:
y = -2(x +3)
x = -3
Substitute x=-3 into equation.
7y + 42 = -14(-3)
7y + 42 = 42
7y = 0
Divide 7, on both sides, to get rid of the coefficient (7), thus, making y the subject.
y = 0 [anything divide or times to zero, will always remain zero]
Following model: (x,y)
