Write an equation of the line that passes through the given point and is parallel to the given line.
saveliy_v [14]

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9

Step-by-step explanation:

Given equation of line is:

y = -2x+7

As the given line is in slope intercept form, the coefficient of x is the slope

Let m1 be the slope of given line

m_1 = -2

Let m2 be the slope of second line then

m_2= -2

The equation of line is given by:

y= m_2x+b

Putting the value of slope

y = -2x+b

Putting the point (4,1) in the equation

y = -2x+b\\1 = -2(4)+b\\1= -8+b\\b = 1+8\\b = 9

Putting the value of b in the equation

y = -2x+9

Hence,

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9

Angles A and B are complementary angles in a right triange. The value of cos(A) is 12/13. What is the value of Tan(A)
Orlov [11]
Using the pythagorean identity, we can find the value of sin(A)

cos^2(A) + sin^2(A) = 1
(12/13)^2 + sin^2(A) = 1
144/169 + sin^2(A) = 1
sin^2(A) = 1 - 144/169
sin^2(A) = 169/169 - 144/169
sin^2(A) = (169 - 144)/169
sin^2(A) = 25/169
sin(A) = sqrt(25/169)
sin(A) = 5/13

Which is then used to find tan(A)

tan(A) = sin(A)/cos(A)
tan(A) = (5/13) divided by (12/13)
tan(A) = (5/13)*(13/12)
tan(A) = (5*13)/(13*12)
tan(A) = 5/12

The final answer is 5/12
