y = -1 + 3/8x
2x - 5y = 6
Substitute the first equation into the second equation, since y is already by itself.
2x - 5(-1 + 3/8x) = 6
2x + 5 - 15/8x = 6
2x - 15/8x = 1
16/8x - 15/8x = 1
1/8x = 1 Multiply 8 on both sides to get x by itself
x = 8
Plug x into either of the equations.
y = -1 + 3/8(8)
y = -1 + 3
y = 2
2(8) - 5y = 6
16 - 5y = 6
-5y = -10
y = 2
(8,2)
Answer:
x = 22√2
Step-by-step explanation:
In a triangle,
AB = 22
B = 90
C = 45
Now,
<em>sin </em><em>C </em><em>=</em><em> </em><em>opp/</em><em>h</em><em>y</em><em>p</em>
<em>sin </em><em>4</em><em>5</em><em> </em><em>=</em><em> </em><em>AB/</em><em>A</em><em>C</em>
<em>1</em><em>/</em><em>√</em><em>2</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>x</em>
<em><u>x = 22√2</u></em>
