To solve for a variable, you must isolate it onto 1 side of the equal sign.
4 + y = -3
Simply subtract 4 on both sides to get:
y = -3 -4
-3-4 is -7 so:
y = -7

4 + y = -3
y = -3 - 4
y = -7 <==

Add 16+12 to get 28.
Add 9+12 to get 21.

Think of these as the sides of a triangle.
a^2+b^2=c^2
28^2+21^2=1225
√1225=35

PLS HELP I DONT UNDERSTAND!! What type of circle would you use when graphing x≥5

inna [77]

How to:

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

For this problem:

For the number line, we would place a solid dot at −5 because the value is both greater than and equal too (≥) and then continue a line on the number line to the right of that point incorporating all values greater than −5

Answer:

(image attached) 

Look at the one showing your problem, the first one.

It's reverse of that since X is greater meaning the line goes the other way instead as shown in the second image.
