8n+3=5
8n=2
N=.25
The number is .25 or 1/4
(3,59)(5,87)
slope = (87 - 59) / (5 - 3) = 28/2 = 14 <== ur slope
y = mx + b
slope(m) = 14
use either of ur points...(3,59)...x = 3 and y = 59
now we sub and find b, the y int
59 = 14(3) + b
59 = 42 + b
59 - 42 = b
17 = b <=== ur y int (0,17)
Answer:
x=1/3 or x=−3/2
Step-by-step explanation:
7x2+10x−3=x2+3x
Step 1: Subtract x^2+3x from both sides.
7x2+10x−3−(x2+3x)=x2+3x−(x2+3x)
6x2+7x−3=0
Step 2: (3x−1)(2x+3)=0
Step 3: Set factors equal to 0.
3x−1=0 or 2x+3=0
x=1/3 or x= −3/2
f(x)=9x²+24x+1
f(x)=(3x)²+ 2×3x× 4 + 1
= (3x)²+2×3x×4 +16 -16 +1
=. ( 3x+4)² -15. -------(1)
then (3x+4)² ≥0
least value of (3x+4)² is 0
putting in equation 1
= 0-15 =-15
- 15 is the least value
