Answer:the domain is every “x” coordinate and the range is the “y” coordinate
Step-by-step explanation:
If you have to tell whether it’s a function or not, all of the x values in the domain will be different for a function, and 2 or more of the same x value won’t be a function
3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
Answer:
the system has a unique solution
Step-by-step explanation:
Start with an equation of a line in standard form,

Solve it for y to put it into the slope-intercept form:


The slope is -a/b.
Now look at your system of equations. The slope of the first equation is -a/b = -2/3. The slope of the second equation is -a/b = -6/5.
You have a system of two linear equations with two lines with different slopes, so the lines must intersect at a single point.
