Y=2x-1 and y=x-8 using substitution

Vitek1552 [10]

Answer:

Step-by-step explanation:

y = 2x - 1

y = x - 8 ------ (i)

substitute y = 2x - 1 in equation (i)

2x - 1 = x - 8

2x = x - 8 + 1

2x = x - 7

2x - x = -7

x = -7

Substitute x value in equation (i)

y = -7 - 8

y = -15

Write the expression as either the sine, cosine, or tangent of a single angle. tan5x - tan2y / 1 + tan5x tan2y

Kryger [21]

$\bf \textit{Sum and Difference Identities}
\\\\
tan(\alpha + \beta) = \cfrac{tan(\alpha)+ tan(\beta)}{1- tan(\alpha)tan(\beta)}
\qquad
tan(\alpha - \beta) = \cfrac{tan(\alpha)- tan(\beta)}{1+ tan(\alpha)tan(\beta)}\\\\
-------------------------------\\\\
\cfrac{tan(5x)-tan(2y)}{1+tan(5x)tan(2y)}\implies tan(5x-2y)$
