Answer:

Step-by-step explanation:

In the equation y = -x - 4, the gradient is -1.

While in the second equation,

5x + 5y = 20

y = -x + 4

So the gradient is -1 too

Both sides are not perpendicular to each other because if you apply the formula, m1m2 = -1, and if substitute both gradient, (-1)(-1) = 1 ≠ -1

Therefore, no they are not perpendicular but parallel instead.

The formula for the area of any triangle is as followed:

$A_{triangle}=\frac{bh}{2}$

-------------------------------------------------------------------------------------------------------------

Let Statements:

Let the variable...

→ $b$ represent the length of the base of the triangle

→ $h$ represent the length of the height of the triangle

-------------------------------------------------------------------------------------------------------------

Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

$10=\frac{(4)(x+3)}{2}$

Distribute the parenthesis (The Distributive Property) :

$10=\frac{((4)(x)+(4)(3))}{2}$

$10=\frac{4x+12}{2}$

Reduce the fraction to lowest terms:

$10=2x+6$

Add -6 to both sides of the equation:

$(10)+(-6)=(2x+6)+(-6)$

$4=2x$

Divide both sides of the equation by 2:

$\frac{4}{2}=\frac{2x}{2}$

$2=x$

-------------------------------------------------------------------------------------------------------------

The Answer to this Problem is:

$\boxed{x=2}$

I hope this helped!

What is the sum of the n terms of the series 4 + 12 + 36 + 108 + . . . ?

arlik [135]

Sum of n terms of a geometric series is
Sn = a1 (r^n-1)/(r-1)
a1 = 1st term = 4
r = common ratio = 12/4 = 3
so, the sum is
Sn = 4 (3^n-1)/(3-1) = 2(3^n-1)

Answer:

439.6 inches

Step-by-step explanation:

The distance apart cna be obtained using the formular :

Number of revolutions = 7

Diameter, d = 20 inches

π * number of revolutions * diameter

3.14 * 7 * 20

= 439.6 inches
