Answer:
131.25
Step-by-step explanation:
25r²-10r+10r-4=0
25r²-4=0 (Since -10 and 10 cancel each other out)
25r²=4
Divide both sides by 4 to get r² = 6.25
Square both sides to get r = 2.5
Plug 2.5 back into the equation to get the answer of 131.25

Answer:
b = 4/3
m = -5/3
Step-by-step explanation:
3=-m+b
-2=2m+b
Subtract the second equation from the first
3=-m+b
-( -2=2m+b)
------------------------
3=-m+b
+ 2=-2m-b
------------------------
5= -3m +0b
Divide by -3
5/-3 = -3m/-3
-5/3 = m
Now we can find b
3=-m+b
3 = - (-5/3) +b
3 = 5/3 +b
Subtract 5/3 from each side
3 -5/3 = b
9/3 - 5/3 = b
4/3 =b
