5r^2 = 80 \ \ /:5\\ \\r^2=\frac{80}{5}\\ \\r^2=16\\ \\r^2-16=0\\ \\ r^2 - 4^2 =0 \\ \\(r-4)(r+4)=0

r-4=0 \ \ \vee \ \ r+4 =0 \\ \\r=4 \ \ \vee \ \ r = -4 \\ \\ \\ a^2-b^2 = (a- b)(a+b)

The line represented by the equation y=-3/2x is translated up 3 units.
kati45 [8]

Answer:

(0, 3)

Step-by-step explanation:

     In slope intercept form, the y-intercept is the "b" or, in an example:

           y = mx + b

     - m is the slope

     - b is the y-intercept

     In our first equation, the b is 0 (y=-3/2x, there is no +/- b, so it is 0). If we add positive 3 (up 3 units) then the y-intercept will be 3. This, in a point, is shown with (0, 3) because the y-intercept is where the line hits the y-axis when x is 0.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

umka2103 [35]

10+25+15=50

25/50

I can be simplified.

The greatest common factor is 25.

25/25=1

50/25=2

So the answer is 1/2.
