Step-by-step explanation:

= √(5 + 2 - 2√10 )

= √{(√5)² +(√2)² - 2.√5.√2}

= √(√5 - √2)² (by identity a² + b² -2ab = ( a-b)²)

= √5 - √2

Answer 2

2 doctors is what percent of 25 doctors

Answers

To find that answer, you have to divide 2 by 25.

That is .08 or 8%

If you have the percent and want to find the nonpercent like 2 of 25, then you multiply .08 by 25 and you get 2.

Hope I helped!!!

A line has a slop of 2 and passes through the point -12,8

Answers

The function of the line would be best represented by y=mx+b where m = slope and b = y intercept.
To find this we can put it into the slope-intercept form of y-y1=m(x-x1)

Which is:
y-8=2(x+12)
y=2x+24+8
y=2x+32
Hope that helps!
y=mx+b
m=slope
b=y intercept

slope=2
y=2x+b
solve for b by inputing
(-12,8)
(x,y)
x=-12 and y=8 is one solution
input -12 for x and 8 for y

8=2(-12)+b
8=-24+b
add 24 to both sides
32=b

y=2x+32
