Ax + by = c......a > 0, b < 0, c < 0...this means a is positive and b and c are negative
ax - by = -c

to find the x int, sub in 0 for y and solve for x
ax - b(0) = -c
ax = -c
x = -c/a <== ur x int

ax - by = -c
-by = -ax - c
y = a/bx + c/b.....slope = a/b , y int = c/b <==

Oksanka [162]

The denominator( s ) we are given are x^2 + 4x + 4, and . The first thing we want to do is factor the expressions, to make this easier -

x^2 + 4x + 4

This expression is a perfect square, as ( x )^2 = x^2, ( 2 )^2 = 4, 2 * ( x ) * ( 2 ) = 4x. Thus, the simplified expression should be the following -

( x + 2 )^2

The other expression is, on the other hand, not a perfect square so we must break this expression into groups and attempt factorization -

x^2 + 5x + 6,\\\left(x^2+2x\right)+\left(3x+6\right),\\x\left(x+2\right)+3\left(x+2\right),\\\left(x+2\right)\left(x+3\right)\\\\Factored Expression = \left(x+2\right)\left(x+3\right)

Combining ( x + 2 )^2 and ( x + 2 )( x + 3 ), the expression that contains factors of each is ( x + 2 )^2 * ( x + 3 ), or in other words the LCM.

<u><em>Solution = </em></u>\left(x+2\right)^2\left(x+3\right)<u><em /></u>

Help needed I need the answer with work shown for the graphs
andreyandreev [35.5K]

top left: speed = 2.7 miles per hour  = 2.7 MPH

top right: speed = 0 miles per hour  = 0 MPH

bottom left: speed = 4 miles per hour  = 4 mi/h

bottom right: speed = 2 miles per hour  = 2 mi/h

and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!

Step-by-step explanation:

key: speed= distance/time

distance= speedxtime

time=distance/speed

top left: 8/3= 2.66667 MPH= 2.7 MPH

top right: 0/8= 0 MPH= 0 MPH

bottom left: 8/2= 4 MPH= 4 MPH

bottom right: 8/4= 2 MPH= 2 MPH
