Mathematics
1 answer:
ASHA 777 [7]3 years ago
3 0

Answer:

see the attached graph

Step-by-step explanation:

When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).

  x +3y = -3

Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:

  x/(-3) +y/(-1) = 1

The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.

Why is the grid in Example 1 a good way to<br> represent a percent?
Tems11 [23]

Answer:

percent means  <u>per hundred </u>

Between the 100 squares, 60 of them are shaded

so you do 60/100

it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100

when you calculate percentage, you do the fraction x 100

so it's 60/100 = 0.6 x100 = 60%

hope that answers your question

1. If you were to describe a TRANSLATION of triangle ABC, what information would you need to include in your description?
cluponka [151]
A translation is when a triangle moves from one location to another while staying the same size/position.

A rotation is when it changes positions, like it can turn upside down or to the side.

A reflection is when it translates over the x or y axis.
