Solve by substitution. Check the solution. y=3x+1
2x+y=-4

solution (_,_)

check in 1st eq:

check in 2nd eq:

( x, y ) = ( -1, -2 )

Step-by-step explanation:

y = 3x + 1 eqn ( I )

And, 2x + y = -4 eqn ( ii )

So,

in eqn ( ii ) putting the value of y.

2x + 3x + 1 = -4

=> 5x = -4 - 1

=> 5x = -5

=> x = -1

Again,

y= 3x+1

so, y= 3 X (-1) + 1

y= -3 + 1

y= -2

So, (x,y) = (-1,-2)

ab will be equal to

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
