Which equation represents a line that passes through the point ( 6 , − 3 ) and is parallel to the graph of y = 3 x + 1 ?

Ratling [72]

Answer:

y + 3= 3(x - 6) ← point-slope form

y = 3x - 21 ← slope-intercept form

3x - y = 21 ← standard form

Step-by-step explanation:

The point-slope form of the equation of line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂

{Two lines are parallel if their slopes are equal}

y = 3x + 1 ⇒ m₁ = 3 ⇒ m₂ = 3

(6, -3) ⇒ x₁ = 6, y₁ = -3

point-slope form:

y - (-3) = 3(x - 6)

y + 3 = 3(x - 6)

y + 3 = 3x - 18 {subtact 3 from both sides}

y = 3x - 21 ← slope-intercept form

-3x + y = -21 {multiply both sides by (-1)}

3x - y = 21 ← standard form

What is z equal to ? Please help

MakcuM [25]

The sum of the interior angles of a triangle (half the rhombus in this case) is 180. Because of the properties of a rhombus, z and x will be equal to each other. Therefore, $124 + z + z = 180$ .
$124 + z + z = 180$
$124 + 2z = 180$
$2z = 56$
$z = 28$
Thus, z is equal to 28.

Jose makes $10000 a month plus some money by commission rates. He gets 6% of everything he sells. If Jose sold $59000 worth of i

IgorC [24]

Answer:

$13540

Step-by-step explanation:

Divide 100 from $59000 in which you get 1% of that worth. If he gets 6% of that commission rate then he would get $3540 since 1% is $590 and you multiply by 6 to get that number. Since he makes $10000 a month as stated, you would then add the amount $3540 for his salary to get $13540.
