The value you should get is 34. I'm assuming n is variable we should use. "the square of a number increased by 9" = "n^2+9" in an algebraic expression. then you plug in. 5^2+9 and then solve. 5^2=25. 25+9=34

Answer:

d:n+9=34

Find the value of y
Rainbow [258]
You'll apply the geometric mean formula. The idea is to multiply the two pieces of the hypotenuse: 5*11 = 55

Then apply the square root to get sqrt(55)

The exact answer in terms of radicals or square roots is sqrt(55)

Using a calculator, the approximate answer is sqrt(55) = 7.416198

If your teacher wants you to use a proportion, then one way to do it is to have
11/y = y/5
11*5 = y*y
55 = y^2
y^2 = 55
y = sqrt(55)
y = 7.416198 approximately

Okay i am begging all of the math wizards on brainly to help me. it is end of the semester for me and im trying so hard not to f
Travka [436]

Answer:

Ok its pretty straight forward

So for every x its 1

And every y its 4/5

To make life simpler lets just make 4/5 into a whole number

So we can make it into 20/5 which equals 4

To get to 20/5 we multiply 4/5 by 5

So we multiply the x by 5 too

We’d get (5,5)

So you can plot that

And the lines should automatically plug in a different point

You can plug it into negatives

-5, -5

so something between those lines

Like i dontt get how lines work here it Make sure its on the 5,5

I can’t think of an equation but I guess

5=m5

In the Format  Y=mx (yes no y intercept because its a direct proportion formula)

Or you can use the format

y/x=m

5/5=m

Or if they suggest it in a y intercept formula

y-mx+b

just plug in like y with 5 and the x with 5.

You can also use the plot (10,8) still works :)

If I’m worng I’m sorry the question is weird and I’m assuming they asking you about Proportional/direct relationships
