Answer: distributing

2(6x + 6) <em>is</em> 12x + 12

16x - 8 <em>is</em> 8(2x - 1)

3(x - 2) <em>is</em> 3x - 6

3(4x + 4) <em>is</em> 12x + 12

2x + 6 <em>is</em> 2(x + 3)

4(x + 3)<em> is</em> 12x + 12

Step-by-step explanation:

Distribute the number in front of the parenthesis to the numbers inside the parenthesis .

for example: 3(x-2)

3 times x = 3x

3 times -2= -6

answer: 3x - 6

Step-by-step explanation:

36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm

36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm

36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm

36D) area of ∆ABC = ½×6.9×4= 13.8 cm²

36E) sin A = sin 30° = 0.5

What's the slope-intercept form that passes through the points (0, -1) and (1, 5)?
Rzqust [24]

Answer:

<h2>         y = 6x - 1</h2>

Step-by-step explanation:

\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}

(0, -1)    ⇒     x₁ = 0,  y₁ = -1

(1, 5)     ⇒     x₂ = 1,  y₂ = 5

So the slope:

                     \bold{m=\dfrac{5+1}{1-0}=\dfrac{6}{1}=6}

The slope-intercept form of the equation of line is y = mx + b, where m is the slope and b is the y-intercept of the line.

(0, -1)    ⇒     x₀ = 0,  y₀ = -1      ⇒   b = -1

Therefore:

                 y = 6x - 1          ←  the slope-intercept form of the equation

The measure of an angle is seventeen times the measure of a supplementary angle. What is the measure of each angle?
blagie [28]
Supplementary angles are two angles that when add equal 180 degrees.
The supplement of an angle is 180 - n.

n = 17(180 - n)
n = 3060 - 17n
n + 17n = 3060
18n = 3060
n = 3060/18
n = 170

so the unknown angle (n) = 170 degrees and its supplement = (180 - 170 = 10)......= 10 degrees.
