Is the ordered pair (5,2) a solution to the equation x+2y=9. Explain.

Yes.

Step-by-step explanation:

You are going to put the y coordinate where the y is in the problem.

Ex. x+2(2)=9

Now you will have x+4=9

The you'll put the x coordinate where the x is in the problem.

Ex. 5+4=9

5+4=9 is correct, so yes it is the solution to the equation.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
