y = mx+b y=17-8x just switch the 8 over and change the sign

The equation 8 x + y = 17 converted to slope-intercept form is y = − 8 x + 17 . In this form, the slope is − 8 and the y-intercept is 17 .

Langkah 1:Gunakan identitas:cos(α + β) = cos α cos β − sin α sin βDiketahui:sin α · sin β = 1/3α − β = π/2Langkah 2:Gunakan identitas:cos(α − β) = cos α cos β + sin α sin βKarena α − β = π/2, maka:cos(α − β) = cos(π/2) = 0Substitusi ke rumus:0 = cos α cos β + sin α sin β→ cos α cos β = − sin α sin β→ cos α cos β = −1/3Langkah 3:Substitusi ke rumus awal:cos(α + β) = cos α cos β − sin α sin β= (−1/3) − (1/3) = −2/3Jawaban akhir:cos(α + β) = −2/3
