(5x^2-21x-20)/(5x^2-16x-16)
((x-5)(5x+4))/((x-4)(5x+4))
(x-5)/(x-4)
5.
y=mx+b
y=1/2x+3
6.
y=mx+b
y=-2x+5
(Just plug in the numbers)
Answer:
17/5
3.4
Step-by-step explanation:
there could be multiple so theres a fraction and a decimal
|2x+3|-1<4
|2x+3|<5
1) when 2x +3 is positive
2x+3<5
2x<2
x<1 (-∞, 1)
2) when 2x+3 is negative
-(2x+3)<5
-2x-3<5
-2x<8
x>-4 (-4, ∞)
(-∞, 1)∩(-4, ∞)=(-4,1)
Answer:
54
Step-by-step explanation:
x is half the difference of the two arcs:
x = (136 -28)/2 = 54
The value of x is 54.
