what is an equation of the line that passes through the point (-3,1) and is parallel to the line 4x+3y=15?

guajiro [1.7K]

$equation \: of \: required \: line \implies$

$4x + 3y + k = 0-----(1)$

$since \: it \: passes \: through \: ( - 3,1),$

$- 12 + 3 + k = 0$

$k = 9$

$substituting \: in \: k = 9 \: in \: (1),$

we get,

$4x + 3y + 9 = 0$

$hence \: the \: equation \: of \: the \: line \implies$

$\red{ \boxed{ \bold{4x + 3y + 9 = 0}}}$

3. The sum of the measures of a complement and a supplement of an angle is 200. What is the measure of the angle?

klasskru [66]

Hi there!

Let th' required angle = X

Then,

• Complement of th' angle = 90 - X
• Supplement of th' angle is = 180 - X

According to th' question,
Sum of Complement and Supplement :-

(90 - X) + (180 - X) = 200

⇒ 90 - X + 180 - X = 200

⇒ 270 - 2X = 200

⇒ 2X = 270 - 200

⇒ 2X = 70

⇒ X = $\dfrac {70}{2}$ = 35

Hence,
Th' measure of the angle is 35°
