True!
For example:
can also represented as
, and the answer will still be 4.
Answer:
C
Step-by-step explanation:
Since the sign is not
, and it is <, then you'd choose the option with the dotted line showing it isn't inclusive.
Answer:

Step-by-step explanation:
$40+$16(that is, 8+8)=56 and 50+6=56
When minusing a negative, the two negative/minus signs become a positive, so it would be a positive add another positive, giving a positive number
Answer:
3x +4 = -2x -1
Step-by-step explanation:
The line that goes up to the right has a y-intercept of +4. This is where it crosses the y-axis. It's slope (rise/run) is 3/1 = 3, so its equation in slope-intercept form is ...
y = mx +b . . . . where m is the slope, b is the y-intercept
<u>y = 3x +4</u>
The other line has a negative slope and a y-intercept of -1. The slope of that line is rise/run = -2/1 = -2, so its equation is ...
<u>y = -2x -1</u>
__
The solution point will have the x-coordinate that is the solution of the equation ...
y = y
3x +4 = -2x -1 . . . . . . substituting the above expressions for y.
