there is a line that includes two point (-1,0) and has a slope of 19. What is its equation in slope-intercept form?

shusha [124]

Answer:

Step-by-step explanation:

m = 19 ; (-1,0)

y - y₁ = m (x - x₁)

y - 0 = 19 (x - [-1] )

y = 19 ( x + 1 )

y = 19x + 19

Figure A is a scale image of figure B What is the value of X

vazorg [7]

Answer:

x = 5.4

Step-by-step explanation:

Since A is the scale image of B,

4/3 = 7.2/x

Cross multiplying,

4x = 3*7.2

Dividing by4,

x = 3*7.2 / 4

x = 5.4

How do I verify the identity: sec(t)+1/tan(t)=tan(t)/sec(t)-1

kompoz [17]

$\bf \textit{Pythagorean Identities}
\\ \quad \\
sin^2(\theta)+cos^2(\theta)=1
\\ \quad \\
1+cot^2(\theta)=csc^2(\theta)
\\ \quad \\
\boxed{1+tan^2(\theta)=sec^2(\theta)}\implies tan^2(\theta)=sec^2(\theta)-1\\\\
-----------------------------\\\\
\cfrac{sec(x)+1}{tan(x)}=\cfrac{tan(x)}{sec(x)-1}\\\\
-----------------------------\\\\$

$\bf \cfrac{sec(x)+1}{tan(x)}\cdot \cfrac{sec(x)-1}{sec(x)-1}\impliedby \textit{using the conjugate}\\\\
-----------------------------\\\\
recall\qquad \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-----------------------------\\\\
thus\qquad \cfrac{sec^2(x)-1^2}{tan(x)sec(x)-1}\implies \cfrac{sec^2(x)-1}{tan(x)sec(x)-1}
\\\\\\
\cfrac{\underline{tan^2(x)}}{\underline{tan(x)} sec(x)-1}\implies \cfrac{tan(x)}{sec(x)-1}$
