Answer:
x=4/14
Step-by-step explanation:
step one:
3x^2+8x-4=0 turns into -
6x+8x-4=0
Step two:
6x+8x-4=0 turns into -
14x-4=0 because you have to combine like terms
Step three:
14x-4= 0 turns into
14x=4 to get x by itself
Step four:
14x=4 turns into -
x=4/14
The hull speed of the Santa Monica in terms of the length, ln of the Nina Pinta is given as a√b where a = 1.34 and b = ln - 10
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that:
v = 1.34√l
where l is the hull length in feet and v is the hull speed in knots.
Santa Monica has a hull length that is 10 ft shorter than that of the Nina Pinta and ln is the length of Nina. Hence:
v = 1.34√(ln - 10) = a√b
The hull speed of the Santa Monica in terms of the length, ln of the Nina Pinta is given as a√b where a = 1.34 and b = ln - 10

Answer:
-2< x< 8
Step-by-step explanation:
|x-3|<5 <=> -5<x-3<5 <=> -2<x<8
..
y = - 4x +3 when slope is -4
NOTE: Parallel lines have same slope.
For the line passing through point (-5, -6) the slope (m) = -4
Equation of that line:
(y - y1) = m (x -x1)
(y --6) = -4(x --5)
(y + 6) = -4(x + 5)
y + 6 = -4x -20
y = -4x -20 -6
y = -4x - 26
