3x - 3 = 13

The next step will be to add 3 to both sides:
3x - 3 + 3 = 13 + 3

⇒ 3x = 16

Answer: 3x = 16

3x = 16 you need to get 3x by itself so you can divide so add the 3 to the other side

Find the equation of the line using exact numbers

Katen [24]

Answer:

y = - $\frac{1}{3}$ x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2-y_{1} } }{x_{2-x_{1} } }$

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = $\frac{4-5}{3-0}$ = $\frac{-1}{3}$ = - $\frac{1}{3}$

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = - $\frac{1}{3}$ x + 5 ← equation of line

How to find the area of composite polygon that have a base of 16 meters height of 18 meters and a height of 11 meters.

LenaWriter [7]

The area of the composite polygon is:

$\boxed{A_{T}=376 \ m^2}$

<h2>Explanation:</h2><h2 />

Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll choose the figure below in order to illustrate this problem. A composite polygon is a polygon that can be divided into two or more basic shapes. So here we have a composite polygon formed by a triangle and a rectangle. So:

$A_{total}=A_{T} \\ \\ A_{triangle}=A_{tr} \\ \\ A_{rectangulo}=A_{r} \\ \\ \\ A_{tr}=\frac{b\times h}{2} \\ \\ b:Base \ of \ the \ triangle \\ \\ h:height \ of \ the \ triangle \\ \\ \\ A_{r}=B\times H \\ \\ B:base \ of \ the \ rectangle \\ \\ H:height \ of \ the \ rectangle$
